What the vulnerability does
01Description
The Auto Refresh Single Page plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1 via deserialization of untrusted input from the arsp_options post meta option. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Explanation of Vulnerability in Simple Terms
02Summary
Auto Refresh Single Page versions 1.1 and earlier contain a deserialization vulnerability that allows authenticated attackers to execute arbitrary code on the site. The vulnerability exists because the plugin deserializes untrusted data without proper validation. An attacker with low-level site access can exploit this to gain full control of the WordPress installation.
