Technical details

The extensions manager in Cotonti through version 1.0.0 fails to validate anti-CSRF tokens on state-changing actions, allowing attackers to forge requests that modify extension states (install, update, pause, unpause) when an authenticated administrator visits a malicious page. The vulnerability requires administrator authentication and user interaction (visiting a crafted link), but no other preconditions. A fix is expected to be available in a patched version.
