Description
PAX Technology Q80 Application Installer Signature Verification Bypass Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PAX Technology Q80. Authentication is not required to exploit this vulnerability.
