snappy-java is a fast compressor/decompressor for Java. Due to unchecked multiplications, an integer overflow may occur in versions prior to 1.1.10.1, causing an unrecoverable fatal error. The function `compress(char[] input)` in the file `Snappy.java` receives an array of characters and compresses it. It does so by multiplying the length by 2 and passing it to the rawCompress` function. Since the length is not tested, the multiplication by two can cause an integer overflow and become negative. The rawCompress function then uses the received length and passes it to the natively compiled maxCompressedLength function, using the returned value to allocate a byte array. Since the maxCompressedLength function treats the length as an unsigned integer, it doesn’t care that it is negative, and it returns a valid value, which is casted to a signed integer by the Java engine. If the result is negative, a `java.lang.NegativeArraySizeException` exception will be raised while trying to allocate the array `buf`. On the other side, if the result is positive, the `buf` array will successfully be allocated, but its size might be too small to use for the compression, causing a fatal Access Violation error. The same issue exists also when using the `compress` functions that receive double, float, int, long and short, each using a different multiplier that may cause the same issue. The issue most likely won’t occur when using a byte array, since creating a byte array of size 0x80000000 (or any other negative value) is impossible in the first place. Version 1.1.10.1 contains a patch for this issue.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - apache-commons-net: FTP client trusts the host from PASV response by default (CVE-2021-37533)

  - Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS).
    If the parser is running on user supplied input, an attacker may supply content that causes the parser to     crash by stack overflow. This effect may support a denial of service attack. (CVE-2022-41854)

  - An infinite recursion is triggered in Jettison when constructing a JSONArray from a Collection that     contains a self-reference in one of its elements. This leads to a StackOverflowError exception being     thrown. (CVE-2023-1436)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2024-0718 advisory.

  - jackson-databind through 2.15.2 allows attackers to cause a denial of service or other unspecified impact     via a crafted object that uses cyclic dependencies. NOTE: the vendor's perspective is that this is not a     valid vulnerability report, because the steps of constructing a cyclic data structure and trying to     serialize it cannot be achieved by an external attacker. (CVE-2023-35116)

  - In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input     string, like //../foo, or \\..\foo, the result would be the same value, thus possibly providing access     to files in the parent directory, but not further above (thus limited path traversal), if the calling     code would use the result to construct a path value. (CVE-2021-29425)

  - snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. The     SnappyInputStream was found to be vulnerable to Denial of Service (DoS) attacks when decompressing data     with a too large chunk size. Due to missing upper bound check on chunk length, an unrecoverable fatal     error can occur. All versions of snappy-java including the latest released version 1.1.10.3 are vulnerable     to this issue. A fix has been introduced in commit `9f8c3cf74` which will be included in the 1.1.10.4     release. Users are advised to upgrade. Users unable to upgrade should only accept compressed data from     trusted sources. (CVE-2023-43642)

  - snappy-java is a fast compressor/decompressor for Java. Due to unchecked multiplications, an integer     overflow may occur in versions prior to 1.1.10.1, causing a fatal error. The function `shuffle(int[]     input)` in the file `BitShuffle.java` receives an array of integers and applies a bit shuffle on it. It     does so by multiplying the length by 4 and passing it to the natively compiled shuffle function. Since the     length is not tested, the multiplication by four can cause an integer overflow and become a smaller value     than the true size, or even zero or negative. In the case of a negative value, a     `java.lang.NegativeArraySizeException` exception will raise, which can crash the program. In a case of a     value that is zero or too small, the code that afterwards references the shuffled array will assume a     bigger size of the array, which might cause exceptions such as `java.lang.ArrayIndexOutOfBoundsException`.
    The same issue exists also when using the `shuffle` functions that receive a double, float, long and     short, each using a different multiplier that may cause the same issue. Version 1.1.10.1 contains a patch     for this vulnerability. (CVE-2023-34453)

  - snappy-java is a fast compressor/decompressor for Java. Due to use of an unchecked chunk length, an     unrecoverable fatal error can occur in versions prior to 1.1.10.1. The code in the function hasNextChunk     in the fileSnappyInputStream.java checks if a given stream has more chunks to read. It does that by     attempting to read 4 bytes. If it wasn't possible to read the 4 bytes, the function returns false.
    Otherwise, if 4 bytes were available, the code treats them as the length of the next chunk. In the case     that the `compressed` variable is null, a byte array is allocated with the size given by the input data.
    Since the code doesn't test the legality of the `chunkSize` variable, it is possible to pass a negative     number (such as 0xFFFFFFFF which is -1), which will cause the code to raise a     `java.lang.NegativeArraySizeException` exception. A worse case would happen when passing a huge positive     value (such as 0x7FFFFFFF), which would raise the fatal `java.lang.OutOfMemoryError` error. Version     1.1.10.1 contains a patch for this issue. (CVE-2023-34455)

  - When deserializing untrusted or corrupted data, it is possible for a reader to consume memory beyond the     allowed constraints and thus lead to out of memory on the system. This issue affects Java applications     using Apache Avro Java SDK up to and including 1.11.2. Users should update to apache-avro version 1.11.3     which addresses this issue. (CVE-2023-39410)

  - Apache Calcite Avatica JDBC driver creates HTTP client instances based on class names provided via     `httpclient_impl` connection property; however, the driver does not verify if the class implements the     expected interface before instantiating it, which can lead to code execution loaded via arbitrary classes     and in rare cases remote code execution. To exploit the vulnerability: 1) the attacker needs to have     privileges to control JDBC connection parameters; 2) and there should be a vulnerable class (constructor     with URL parameter and ability to execute code) in the classpath. From Apache Calcite Avatica 1.22.0     onwards, it will be verified that the class implements the expected interface before invoking its     constructor. (CVE-2022-36364)

  - A temp directory creation vulnerability exists in all versions of Guava, allowing an attacker with access     to the machine to potentially access data in a temporary directory created by the Guava API     com.google.common.io.Files.createTempDir(). By default, on unix-like systems, the created directory is     world-readable (readable by an attacker with access to the system). The method in question has been marked     @Deprecated in versions 30.0 and later and should not be used. For Android developers, we recommend     choosing a temporary directory API provided by Android, such as context.getCacheDir(). For other Java     developers, we recommend migrating to the Java 7 API java.nio.file.Files.createTempDirectory() which     explicitly configures permissions of 700, or configuring the Java runtime's java.io.tmpdir system property     to point to a location whose permissions are appropriately configured. (CVE-2020-8908)

  - Use of Java's default temporary directory for file creation in `FileBackedOutputStream` in Google Guava     versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the     machine with access to the default Java temporary directory to be able to access the files created by the     class. Even though the security vulnerability is fixed in version 32.0.0, we recommend using version     32.0.1 as version 32.0.0 breaks some functionality under Windows. (CVE-2023-2976)

  - Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to     conduct denial of service attacks against servers that depend on this library and deserialize attacker-     provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the     CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without     appropriate checks on what a client has sent and whether the data size is reasonable. (CVE-2018-10237)

  - aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. aiohttp v3.8.4 and earlier     are bundled with llhttp v6.0.6. Vulnerable code is used by aiohttp for its HTTP request parser when     available which is the default case when installing from a wheel. This vulnerability only affects users of     aiohttp as an HTTP server (ie `aiohttp.Application`), you are not affected by this vulnerability if you     are using aiohttp as an HTTP client library (ie `aiohttp.ClientSession`). Sending a crafted HTTP request     will cause the server to misinterpret one of the HTTP header values leading to HTTP request smuggling.
    This issue has been addressed in version 3.8.5. Users are advised to upgrade. Users unable to upgrade can     reinstall aiohttp using `AIOHTTP_NO_EXTENSIONS=1` as an environment variable to disable the llhttp HTTP     request parser implementation. The pure Python implementation isn't vulnerable. (CVE-2023-37276)

  - aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP     has numerous problems with header parsing, which could lead to request smuggling. This parser is only used     when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in     commit `d5c12ba89` which has been included in release version 3.8.6. Users are advised to upgrade. There     are no known workarounds for these issues. (CVE-2023-47627)

  - urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header     special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.
    However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP     redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been     patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)

  - urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP     request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method     changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs.
    Although this behavior is not specified in the section for redirects, it can be inferred by piecing     together information from different sections and we have observed the behavior in other major HTTP client     implementations like curl and web browsers. Because the vulnerability requires a previously trusted     service to become compromised in order to have an impact on confidentiality we believe the exploitability     of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request     bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions     must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information     in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts     redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised.
    This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve     this issue. Users unable to update should disable redirects for services that aren't expecting to respond     with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle     301, 302, and 303 redirects manually by stripping the HTTP request body. (CVE-2023-45803)

  - Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL     certificates while verifying the identity of TLS hosts. Certifi prior to version 2023.07.22 recognizes     e-Tugra root certificates. e-Tugra's root certificates were subject to an investigation prompted by     reporting of security issues in their systems. Certifi 2023.07.22 removes root certificates from e-Tugra     from the root store. (CVE-2023-37920)

  - When installing a package from a Mercurial VCS URL (ie pip install hg+...) with pip prior to v23.3, the     specified Mercurial revision could be used to inject arbitrary configuration options to the hg clone     call (ie --config). Controlling the Mercurial configuration can modify how and which repository is     installed. This vulnerability does not affect users who aren't installing from Mercurial. (CVE-2023-5752)

  - Python Packaging Authority (PyPA) setuptools before 65.5.1 allows remote attackers to cause a denial of     service via HTML in a crafted package or custom PackageIndex page. There is a Regular Expression Denial of     Service (ReDoS) in package_index.py. (CVE-2022-40897)

  - A ReDoS issue was discovered in pygments/lexers/smithy.py in pygments through 2.15.0 via SmithyLexer.
    (CVE-2022-40896)

  - An issue discovered in Python Packaging Authority (PyPA) Wheel 0.37.1 and earlier allows remote attackers     to cause a denial of service via attacker controlled input to wheel cli. (CVE-2022-40898)

  - Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to     destination servers when redirected to an HTTPS endpoint. This is a product of how we use     `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent     through the tunnel, the proxy will identify the header in the request itself and remove it prior to     forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must     be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in     Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious     actor to potentially exfiltrate sensitive information. This issue has been patched in version 2.31.0.
    (CVE-2023-32681)

  - An issue discovered in Python Charmers Future 0.18.2 and earlier allows remote attackers to cause a denial     of service via crafted Set-Cookie header from malicious web server. (CVE-2022-40899)

  - python-idna: potential DoS via resource consumption via specially crafted inputs to idna.encode()     (CVE-2024-3651)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of IBM Engineering Requirements Management DOORS (formerly IBM Rational DOORS) installed on the remote host is 9.7.2.x prior to 9.7.2.8. It is, therefore, affected by multiple vulnerabilities as referenced in the 7124058 advisory.

  - Apache Shiro before 1.9.1, A RegexRequestMatcher can be misconfigured to be bypassed on some servlet     containers. Applications using RegExPatternMatcher with `.` in the regular expression are possibly     vulnerable to an authorization bypass. (CVE-2022-32532)

  - The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow     a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary     shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client     or the broker (respectively) to instantiate any class on the classpath. Users are recommended to upgrade     both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 which fixes this issue.
    (CVE-2023-46604)

  - Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be     exploited. There is only a risk in conjunction with Java object deserialization within an application. In     such situations, it allows attackers to erase contents of arbitrary files, make network connections, or     possibly run arbitrary code (specifically, Function0 functions) via a gadget chain. (CVE-2022-36944)

  - IBM Engineering Requirements Management DOORS 9.7.2.7 is vulnerable to cross-site request forgery which     could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the     website trusts. IBM X-Force ID: 251216. (CVE-2023-28949)

  - A cross-site scripting (XSS) vulnerability in the HTML Data Processor for CKEditor 4.0 before 4.14 allows     remote attackers to inject arbitrary web script through a crafted protected comment (with the     cke_protected syntax). (CVE-2020-9281)
