The 8.1.0 versions of MySQL Connectors installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2023 CPU advisory.

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions     that are affected are 8.1.0 and prior. Difficult to exploit vulnerability allows unauthenticated attacker     with network access via multiple protocols to compromise MySQL Connectors. Successful attacks require     human interaction from a person other than the attacker and while the vulnerability is in MySQL     Connectors, attacks may significantly impact additional products (scope change). Successful attacks of     this vulnerability can result in takeover of MySQL Connectors. (CVE-2023-22102)

  - Vulnerability in the MySQL Enterprise Monitor product of Oracle MySQL (component: Monitoring: General     (OpenSSL)). Supported versions that are affected are 8.0.35 and prior. Easily exploitable vulnerability     allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Enterprise     Monitor. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial     denial of service (partial DOS) of MySQL Enterprise Monitor. (CVE-2023-3817)

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

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 22df5074-71cd-11ee-85eb-84a93843eb75 advisory.

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.

  - Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be     very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL     subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to     very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT     IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit.
    OBJ_obj2txt() may be used to translate an ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the     OpenSSL type ASN1_OBJECT) to its canonical numeric text form, which are the sub-identifiers of the OBJECT     IDENTIFIER in decimal form, separated by periods. When one of the sub-identifiers in the OBJECT IDENTIFIER     is very large (these are sizes that are seen as absurdly large, taking up tens or hundreds of KiBs), the     translation to a decimal number in text may take a very long time. The time complexity is O(n^2) with 'n'     being the size of the sub-identifiers in bytes (*). With OpenSSL 3.0, support to fetch cryptographic     algorithms using names / identifiers in string form was introduced. This includes using OBJECT IDENTIFIERs     in canonical numeric text form as identifiers for fetching algorithms. Such OBJECT IDENTIFIERs may be     received through the ASN.1 structure AlgorithmIdentifier, which is commonly used in multiple protocols to     specify what cryptographic algorithm should be used to sign or verify, encrypt or decrypt, or digest     passed data. Applications that call OBJ_obj2txt() directly with untrusted data are affected, with any     version of OpenSSL. If the use is for the mere purpose of display, the severity is considered low. In     OpenSSL 3.0 and newer, this affects the subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS. It also impacts     anything that processes X.509 certificates, including simple things like verifying its signature. The     impact on TLS is relatively low, because all versions of OpenSSL have a 100KiB limit on the peer's     certificate chain. Additionally, this only impacts clients, or servers that have explicitly enabled client     authentication. In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects, such as X.509     certificates. This is assumed to not happen in such a way that it would cause a Denial of Service, so     these versions are considered not affected by this issue in such a way that it would be cause for concern,     and the severity is therefore considered low. (CVE-2023-2650)

  - Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary:
    Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key     or DH parameters may experience long delays. Where the key or parameters that are being checked have been     obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs     various checks on DH parameters. After fixing CVE-2023-3446 it was discovered that a large q parameter     value can also trigger an overly long computation during some of these checks. A correct q value, if     present, cannot be larger than the modulus p parameter, thus it is unnecessary to perform these checks if     q is larger than p. An application that calls DH_check() and supplies a key or parameters obtained from an     untrusted source could be vulnerable to a Denial of Service attack. The function DH_check() is itself     called by a number of other OpenSSL functions. An application calling any of those other functions may     similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check().
    Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the -check     option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS     providers are not affected by this issue. (CVE-2023-3817)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to     pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting     done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected     to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due     to this bug, the local variable that means let the host resolve the name could get the wrong value     during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target     buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,     and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and     curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in     length, it will switch to local name resolution in order to resolve the address before passing it on to     the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a     slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the     target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation     scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an     attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server     latency is likely slow enough to trigger this bug. (CVE-2023-38545)
