CVE-2024-2501: CWE-502 Deserialization of Untrusted Data in nerdpressteam Hubbub Lite – Fast, free social sharing and follow buttons
The Hubbub Lite – Fast, Reliable Social Sharing Buttons plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.33.1 via deserialization of untrusted input via the 'dpsp_maybe_unserialize' function. This makes it possible for authenticated attackers, with contributor access and above, to inject a PHP Object. No 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-2024-2501 is a deserialization of untrusted data vulnerability (CWE-502) in the Hubbub Lite – Fast, free social sharing and follow buttons WordPress plugin by nerdpressteam. The vulnerability exists in all versions up to and including 1.33.1, specifically in the 'dpsp_maybe_unserialize' function, which improperly deserializes user-controllable input. This allows authenticated users with contributor or higher roles to inject PHP objects. Although the plugin does not include a PHP Object Injection gadget chain itself, exploitation is possible if other plugins or themes installed on the same WordPress instance provide such chains, potentially leading to arbitrary file deletion, sensitive data disclosure, or remote code execution.
Potential Impact
Successful exploitation requires authenticated access with contributor or higher privileges. Without a gadget chain in the plugin itself, direct exploitation is limited; however, if other plugins or themes provide suitable gadget chains, attackers could achieve critical impacts including arbitrary file deletion, sensitive data exposure, or remote code execution. The vulnerability affects confidentiality, integrity, and availability of the affected WordPress site.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Since the plugin is not a cloud service, remediation depends on the vendor releasing an update. Until a fix is released, limit contributor-level access to trusted users only and consider disabling or removing the plugin if possible. Monitor the vendor advisory for updates regarding patches or official mitigations.
