** UNSUPPORTED WHEN ASSIGNED ** When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (ie, deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed could exhaust the available memory in the virtual machine and achieve Denial of Service when the object is deserialized. This issue affects Apache Log4j before 2. Affected users are recommended to update to Log4j 2.x. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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.
