The version of log4j-cve-2021-44228-hotpatch installed on the remote host is prior to 1.3-5. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1806 advisory.

    Versions of the Apache Log4j hotpatch package before log4j-cve-2021-44228-hotpatch-1.3-5 are affected by a     race condition that could lead to a local privilege escalation.

    The Apache Log4j Hotpatch is not a replacement for updating to a log4j version that mitigates     CVE-2021-44228 or CVE-2021-45046, it provides a temporary mitigation to CVE-2021-44228 by hotpatching     local Java virtual machines. To do so, the hotpatch script iterates through all running Java processes,     performs several checks, and executes the Java virtual machine with the same permissions and capabilities     as the running process to load the hotpatch.

    A local user could cause the hotpatch script to execute a binary with elevated privileges by running a     custom java process which performs exec() of a set user ID binary after the hotpatch has     observed the process path and before it has observed its effective user ID.

    To leverage this issue a user must already have local access to the target system with permissions to run     custom programs.

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

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