High · 7.7 Public exploit CVE-2023-1326 EUVD-2023-23584GHSA-qgrc-7333-5cgx

local privilege escalation in apport-cli

Published Apr 13, 2023 · Updated Feb 7, 2025 · Assigned by canonical

Vendor: Canonical Product: Apport Package: apport Ecosystem: Ubuntu

Description

A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit.
