Descripción técnica

In AVideo through 29.0, the CloneSite plugin is vulnerable to stored OS command injection. In plugin/CloneSite/cloneClient.json.php (line ~270) the stored SSH password is substituted into the command string `sshpass -p '{password}' rsync ...` with a plain str_replace and no escaping, so a single quote in the password breaks out of the quoted word and injects arbitrary shell. The password is written through the admin-only endpoint objects/pluginAddDataObject.json.php, whose only CSRF defense (isUntrustedRequest()/forbidIfIsUntrustedRequest()) is a no-op when the request source appears to be loopback — as happens behind a same-host TLS-terminating reverse proxy with $global['trustedProxies'] unset — or when an attacker-controlled application is co-hosted on the same hostname; on HTTPS the session cookie is issued with SameSite=None, so a cross-site POST carries it. An unauthenticated remote attacker can therefore lure an authenticated administrator into planting a malicious password (and an attacker-controlled cloneSiteURL), after which the plugin's documented crontab entry executes the injected command with no further administrator action, as the crontab owner (commonly root or www-data). Exploitation requires the CloneSite plugin to be enabled with the documented crontab installed and one of the above CSRF channels; default single-process Apache deployments are reported as not CSRF-exploitable. This is a residual sink of CVE-2026-41304. The issue is confirmed at master HEAD (8963b6a1); no patched version is available.
