CVE-2024-1858: CWE-502 Deserialization of Untrusted Data in weblizar Lightbox slider – Responsive Lightbox Gallery
The Lightbox slider – Responsive Lightbox Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.9.9 via deserialization of untrusted input through post meta data. 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.
AI Analysis
Technical Summary
CVE-2024-1858 is a deserialization of untrusted data vulnerability (CWE-502) in the Lightbox slider – Responsive Lightbox Gallery WordPress plugin, affecting all versions up to 1.9.9. It allows authenticated users with contributor or higher privileges to inject PHP objects through post meta data deserialization. The plugin itself does not contain a known POP chain, but if other plugins or themes installed on the same WordPress instance provide such chains, attackers could leverage this to perform destructive or unauthorized actions such as deleting files, accessing sensitive information, or executing arbitrary code.
Potential Impact
The vulnerability enables authenticated attackers with contributor-level access or above to inject PHP objects, potentially leading to arbitrary file deletion, sensitive data exposure, or code execution if a suitable POP chain exists via other installed plugins or themes. The direct impact on confidentiality and integrity is rated as low to medium, with no impact on availability noted. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and monitor for updates from the vendor. Avoid installing untrusted plugins or themes that could provide POP chains enabling exploitation.
