Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.

The remote Redhat Enterprise Linux 5 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.

  - log4j: deserialization of untrusted data in SocketServer (CVE-2019-17571)

  - In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive     serialized log events from another application, a specially crafted binary payload can be sent that, when     deserialized, can execute arbitrary code. (CVE-2017-5645)

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 remote host is affected by the vulnerability described in GLSA-202402-16 (Apache Log4j: Multiple Vulnerabilities)

  - Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data     which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when     listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
    (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an     SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent     through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 (CVE-2020-9488)

  - A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious     code execution. (CVE-2020-9493)

  - JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker     has write access to the Log4j configuration or if the configuration references an LDAP service the     attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing     JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to     CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which     is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2     as it addresses numerous other issues from the previous versions. (CVE-2022-23302)

  - By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the     values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be     included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or     headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue     only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default.
    Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized     SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of     life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the     previous versions. (CVE-2022-23305)

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

The version of log4j installed on the remote host is prior to 1.2.17-17. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1739 advisory.

  - Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from     uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread     Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed     in Log4j 2.17.0, 2.12.3, and 2.3.1. (CVE-2021-45105)

  - When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to     7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the     server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is     configured with sessionAttributeValueClassNameFilter=null (the default unless a SecurityManager is used)     or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker     knows the relative file path from the storage location used by FileStore to the file the attacker has     control over; then, using a specifically crafted request, the attacker will be able to trigger remote code     execution via deserialization of the file under their control. Note that all of conditions a) to d) must     be true for the attack to succeed. (CVE-2020-9484)

  - The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability into Apache Tomcat     10.1.0-M1 to 10.1.0-M8, 10.0.0-M5 to 10.0.14, 9.0.35 to 9.0.56 and 8.5.55 to 8.5.73 that allowed a local     attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue     is only exploitable when Tomcat is configured to persist sessions using the FileStore. (CVE-2022-23181)

  - A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is     a setuid tool designed to allow unprivileged users to run commands as privileged users according     predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly     and ends trying to execute environment variables as commands. An attacker can leverage this by crafting     environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully     executed the attack can cause a local privilege escalation given unprivileged users administrative rights     on the target machine. (CVE-2021-4034)

  - A flaw memory leak in the Linux kernel performance monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this flaw to starve the resources causing denial of     service. (CVE-2020-25704)

  - An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka     CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system     crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as     CVE-2021-28950. (CVE-2020-36322)

  - The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to     drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt     mishandles bounds checking. (CVE-2021-42739)

  - In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server     could cause a heap overflow (CVE-2021-26691)

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules     pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache     HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

The version of log4j installed on the remote host is prior to 1.2.17-16.12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1562 advisory.

    It was found that when using remote logging with log4j socket server the log4j server would deserialize     any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log     event that, during deserialization, would execute arbitrary code in the context of the logger application.
    (CVE-2017-5645)

    A flaw was discovered in Log4j, where a vulnerable SocketServer class may lead to the deserialization of     untrusted data. This flaw allows an attacker to remotely execute arbitrary code when combined with a     deserialization gadget. (CVE-2019-17571)

    A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSAppender in Log4j 1.x is     vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the     server if the deployed application is configured to use JMSAppender and to the attacker's JNDI LDAP     endpoint. (CVE-2021-4104)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

According to its self-reported version number, the installation of Apache Log4j on the remote host is 1.x and is no longer supported. Log4j reached its end of life prior to 2016. Additionally, Log4j 1.x is affected by multiple vulnerabilities, including :

  - Log4j includes a SocketServer that accepts serialized log events and deserializes them without verifying whether     the objects are allowed or not. This can provide an attack vector that can be exploited. (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS     connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that     appender. (CVE-2020-9488)

  - JMSSink uses JNDI in an unprotected manner allowing any application using the JMSSink to be vulnerable if it is     configured to reference an untrusted site or if the site referenced can be accesseed by the attacker.
    (CVE-2022-23302)

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.

An attacker can take advantage of this flaw to execute arbitrary code in the context of the logger application by sending a specially crafted log event.

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the CPUApr2020 advisory.

  - A remote code execution vulnerability exists in the Log4j SocketServer class due to unsafe deserialization of     untrusted data. An unauthenticated, remote attacker can exploit this to remotely execute arbitrary code when     combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j     versions up to 1.2 up to 1.2.17. (CVE-2019-17571)

  - An information disclosure vulnerability exists in the Console component. An unauthenticated, remote attacker can     exploit this to gain unauthorized read access to a subset of Oracle WebLogic Server accessible data. (CVE-2020-2766)

  - A vulnerability in the WLS Web Services component exists. An authenticated, remote attacker can exploit this via T3     to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle     WebLogic Server. (CVE-2020-2798)

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

This update for log4j fixes the following issues :

  - CVE-2019-17571: Fixed a remote code execution by     deserialization of untrusted data in SocketServer     (bsc#1159646).

This update was imported from the SUSE:SLE-15:Update update project.

Included in Log4j 1.2, a logging library for Java, is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data.

For Debian 8 'Jessie', this problem has been fixed in version 1.2.17-5+deb8u1.

We recommend that you upgrade your apache-log4j1.2 packages.

An update is now available for Red Hat JBoss Web Server 3.1 for RHEL 6 and Red Hat JBoss Web Server 3.1 for RHEL 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library.

This release of Red Hat JBoss Web Server 3.1 Service Pack 1 serves as a replacement for Red Hat JBoss Web Server 3.1, and includes bug fixes, which are documented in the Release Notes document linked to in the References.

Security Fix(es) :

* It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. (CVE-2017-5645)

* A vulnerability was discovered in tomcat's handling of pipelined requests when 'Sendfile' was used. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

* A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of the custom error page. (CVE-2017-5664)

* A vulnerability was discovered in tomcat. When running an untrusted application under a SecurityManager it was possible, under some circumstances, for that application to retain references to the request or response objects and thereby access and/or modify information associated with another web application. (CVE-2017-5648)

The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2017:3399 advisory.

  - log4j: Socket receiver deserialization vulnerability (CVE-2017-5645)

  - log4j: deserialization of untrusted data in SocketServer (CVE-2019-17571)

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

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2811 advisory.

    The eap7-jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running     on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

    With this update, the eap7-jboss-ec2-eap package has been updated to ensure compatibility with Red Hat     JBoss Enterprise Application Platform 7.0.8.

    Refer to the JBoss Enterprise Application Platform 7.0.8 Release Notes, linked to in the References     section, for information on the most significant bug fixes and enhancements included in this release.

    Security Fix(es):

    * It was found that when using remote logging with log4j socket server the log4j server would deserialize     any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log     event that, during deserialization, would execute arbitrary code in the context of the logger application.
    (CVE-2017-5645)

    * A vulnerability was found in Jasypt that would allow an attacker to perform a timing attack on password     hash comparison. (CVE-2014-9970)

    * It was found that an information disclosure flaw in Bouncy Castle could enable a local malicious     application to gain access to user's private information. (CVE-2015-6644)

    * It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces     special strings for obtaining attribute values with system property. This could allow an attacker to     determine values of system properties at the attacked system by formatting the SAML request ID field to be     the chosen system property which could be obtained in the InResponseTo field in the response.
    (CVE-2017-2582)

    * It was found that when the security manager's reflective permissions, which allows it to access the     private members of the class, are granted to Hibernate Validator, a potential privilege escalation can     occur. By allowing the calling code to access those private members without the permission an attacker may     be able to validate an invalid instance and access the private member value via     ConstraintViolation#getInvalidValue(). (CVE-2017-7536)

    The CVE-2017-2582 issue was discovered by Hynek Mlnarik (Red Hat) and the CVE-2017-7536 issue was     discovered by Gunnar Morling (Red Hat).
