Lifecycle Timeline
3Description
The education theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.6.10 via deserialization of untrusted input in the 'themerex_callback_view_more_posts' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Analysis
The education theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.6.10 via deserialization of untrusted input in the 'themerex_callback_view_more_posts' function. This makes it possible for unauthenticated attackers to inject a PHP Object.

If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Technical Context
Insecure deserialization occurs when untrusted data is used to reconstruct objects, allowing attackers to manipulate serialized data to execute arbitrary code. This vulnerability is classified as Deserialization of Untrusted Data (CWE-502).
Remediation
Avoid deserializing untrusted data. Use safe serialization formats (JSON instead of native serialization). Implement integrity checks on serialized data.
