Executive brief
The Barber Shop, a WordPress theme by Themeton, contains a critical security flaw that allows attackers to inject malicious objects into the website's memory. This vulnerability can be exploited remotely without any user interaction or login credentials. If successful, an attacker could potentially take full control of the website, steal sensitive data, or disrupt services.
Technical details
The Barber Shop theme (versions up to and including 1.9) is vulnerable to PHP Object Injection due to the insecure deserialization of user-supplied input (CWE-502). An unauthenticated remote attacker can exploit this by sending specially crafted input to a vulnerable component within the theme. If a suitable Property-Oriented Programming (POP) chain is present on the server, this can lead to various high-impact attacks including remote code execution, SQL injection, or arbitrary file deletion. As of the latest advisory, no official patch has been released by the vendor.
