CVE-2023-22809 (GCVE-0-2023-22809)

Vulnerability from cvelistv5 – Published: 2023-01-18 00:00 – Updated: 2025-04-04 15:45
VLAI
Summary
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='vim -- /path/to/extra/file' value.

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=\u0027vim -- /path/to/extra/file\u0027 value."
