CVE-2024-5649: CWE-502 Deserialization of Untrusted Data in webhuntinfotech Universal Slider
The Universal Slider plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.6.5 via deserialization of untrusted input 'fsl_get_gallery_value' function. 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 software. 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-2024-5649 is a deserialization vulnerability (CWE-502) in the Universal Slider WordPress plugin (versions up to 1.6.5). It allows authenticated users with Contributor or higher privileges to inject PHP objects through the 'fsl_get_gallery_value' function. The plugin itself does not contain a known POP chain for exploitation; however, if a POP chain exists in other installed plugins or themes, this vulnerability could be leveraged to perform unauthorized actions such as deleting files, accessing sensitive information, or executing arbitrary code.
Potential Impact
The vulnerability enables authenticated users with Contributor-level access or above to inject PHP objects via deserialization. Without a POP chain in the plugin itself, direct exploitation is limited, but combined with other vulnerable components, it could lead to significant impacts including arbitrary file deletion, sensitive data exposure, or remote code execution. The CVSS score of 5.4 reflects a medium impact primarily on confidentiality and integrity, with no impact on availability.
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 and above to trusted users only. Monitor for updates from the vendor or security advisories regarding patches or workarounds. Avoid installing or enabling additional plugins or themes that could provide a POP chain exploitable in conjunction with this vulnerability.
