CVSS v2.0
9.0
High
| Vector | AV:N/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Sudo versions prior to 1.8.28
Description
The issue allows an attacker with access to a Runas ALL sudoer account to bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID, such as
-1 or 4294967295. This can enable the execution of commands as root even when restricted. The vulnerability exists due to insufficient input validation in Sudo.Recommendations
For Sudo versions prior to 1.8.28, update to version 1.8.28 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
sudo command with crafted user IDs, such as -1 or 4294967295, to minimize the risk of exploitation.Exploit
