Name of the Vulnerable Software and Affected Versions 7-Zip versions prior to 23.01

Description A vulnerability arises out of a failure to comprehensively sanitize the processing of a zip file(s). Incomplete neutralization of external commands used to control the process execution of the .zip application allows an authorized user to obtain control of the .zip application to execute arbitrary commands or obtain elevation of system privileges.

Recommendations For versions prior to 23.01, update to version 23.01 or later to resolve the issue. As a temporary workaround, consider restricting access to the zip application to minimize the risk of exploitation. Avoid using external commands to control the process execution of the .zip application until the issue is resolved.
