28) Improper Check for Dropped Privileges

EUVDB-ID: #VU24690

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2019-18276

CWE-ID: CWE-273 - Improper Check for Dropped Privileges

Exploit availability: Yes

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.
