CVE-2023-22809

En Sudo anterior a 1.9.12p2, la función sudoedit (también conocida como -e) maneja mal argumentos adicionales pasados en las variables de entorno proporcionadas por el usuario (SUDO_EDITOR, VISUAL y EDITOR), permitiendo a un atacante local agregar entradas arbitrarias a la lista de archivos para procesar. . Esto puede conducir a una escalada de privilegios. Las versiones afectadas son 1.8.0 a 1.9.12.p1. El problema existe porque un editor especificado por el usuario puede contener un argumento "--" que anula un mecanismo de protección, por ejemplo, un valor EDITOR='vim -- /path/to/extra/file'.

A vulnerability was found in sudo. Exposure in how sudoedit handles user-provided environment variables leads to arbitrary file writing with privileges of the RunAs user (usually root). The prerequisite for exploitation is that the current user must be authorized by the sudoers policy to edit a file using sudoedit.
