ID:5834 - Exploit for Improper Check for Dropped Privileges in Bash - CVE-2019-18276

Link to public exploit:

Vulnerability description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in "disable_priv_mode()" function in shell.c due to the affected software attempts to drop privileges but does not check or incorrectly checks to see if the drop succeeded. A local user with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges.
