CVE-2024-1724Public exploit

Sandbox escape via writable $HOME/bin symlink

Published Jul 25, 2024 · Updated Aug 1, 2024

Sandbox escape in Canonical snapd before 2.62 allows local users to run scripts outside snap confinement through a malicious snap. The homeConnectedPlugAppArmor policy blocks writes beneath $HOME/bin but fails to block creation of $HOME/bin itself as a symlink to a snap-controlled directory. Exploitation requires AppArmor enforcement, a snap using the automatically connected home interface, installation by the victim, and later execution of a planted PATH command.
