Sudoedit Extra Arguments Privilege Escalation

This exploit takes advantage of a vulnerability in sudoedit, part of the sudo package. The sudoedit (aka sudo -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. by appending extra entries on /etc/sudoers allowing for execution of an arbitrary payload with root privileges. Affected versions are 1.8.0 through 1.9.12.p1. However, this module only works against Ubuntu 22.04 and 22.10. This module was tested against sudo 1.9.9-1ubuntu2 on Ubuntu 22.04 and 1.9.11p3-1ubuntu1 on Ubuntu 22.10.

Ubuntu Security Notice USN-5811-1

Ubuntu Security Notice 5811-1 - Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly handled user-specified editors when using the sudoedit command. A local attacker that has permission to use the sudoedit command could possibly use this issue to edit arbitrary files. It was discovered that the Protobuf-c library, used by Sudo, incorrectly handled certain arithmetic shifts. An attacker could possibly use this issue to cause Sudo to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS.

Debian Security Advisory 5321-1

Debian Linux Security Advisory 5321-1 - Matthieu Barjole and Victor Cutillas discovered that sudoedit in sudo, a program designed to provide limited super user privileges to specific users, does not properly handle '--' to separate the editor and arguments from files to edit. A local user permitted to edit certain files can take advantage of this flaw to edit a file not permitted by the security policy, resulting in privilege escalation.

CVE-2023-22809

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.
