CVE-2024-3070: CWE-502 Deserialization of Untrusted Data in jottlieb Last Viewed Posts by WPBeginner
The Last Viewed Posts by WPBeginner plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.0 via deserialization of untrusted input from the LastViewedPosts Cookie. This makes it possible for unauthenticated attackers 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.
AI Analysis
Technical Summary
CVE-2024-3070 is a critical PHP Object Injection vulnerability in the Last Viewed Posts by WPBeginner WordPress plugin (up to version 1.0.0). It arises from unsafe deserialization of untrusted input from the LastViewedPosts cookie. Without authentication, attackers can inject PHP objects. The plugin itself does not contain a gadget chain (POP chain) for exploitation, but if combined with other installed plugins or themes that provide such chains, it could enable severe impacts including arbitrary file deletion, sensitive data retrieval, or remote code execution.
Potential Impact
Successful exploitation can lead to high-impact outcomes such as complete compromise of the affected WordPress site, including code execution, data theft, and file deletion. The vulnerability is exploitable remotely without authentication, increasing risk. However, exploitation depends on the presence of a POP chain in other installed components, which is not present in the vulnerable plugin alone.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. In the meantime, consider disabling or removing the Last Viewed Posts by WPBeginner plugin if it is not essential. Review other installed plugins and themes for potential POP chains that could be combined with this vulnerability to enable exploitation.
