CVE-2019-9924

Name of the Vulnerable Software and Affected Versions Bash versions prior to 4.4-beta2

Description The issue is related to the restricted command interpreter rbash in Bash, which is associated with insufficient checking of the BASH CMDS array values. This could allow an attacker to execute arbitrary commands. The problem arises because rbash does not prevent the shell user from modifying BASH CMDS, thus enabling the user to execute any command with the permissions of the shell.

Recommendations For versions prior to 4.4-beta2, update to version 4.4-beta2 or later to resolve the issue. As a temporary workaround, consider restricting access to the BASH CMDS array to minimize the risk of exploitation.
