Technical details

An OS command injection vulnerability (CWE-78) exists in the upload_settings.cgi interface due to insufficient input filtering on the restorekey field before it is concatenated into a shell command. The vulnerability requires valid administrative credentials and network access to the device's web management interface. An authenticated attacker can supply crafted input containing shell metacharacters to the restorekey parameter and execute arbitrary OS commands with root privileges. Patches are available in firmware versions 1.4.11 through 1.4.22 depending on the model.
