asepsaepdin/cve-2023-22809Automated local privilege escalation exploit for CVE-2023-22809 (sudoedit -e) that checks sudo permissions and modifies sudoers to gain a root shell. For authorized security testing.
In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='nano -- /path/to/extra/file' value.
This script automates the exploitation of the CVE-2023-22809 vulnerability to gain a root shell.
The script checks if the current user has access to run the sudoedit or sudo -e command for some file with root privileges. If it does it opens the sudoers file for the attacker to introduce the privilege escalation policy for the current user and get a root shell.
