CVE-2024-2693: CWE-502 Deserialization of Untrusted Data in linkwhspr Link Whisper Free
The Link Whisper Free plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.7.1 via deserialization of untrusted input of the 'mfn-page-items' post meta value. 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-2024-2693 is a high-severity PHP Object Injection vulnerability (CWE-502) in the Link Whisper Free WordPress plugin (up to version 0.7.1). It arises from unsafe deserialization of the 'mfn-page-items' post meta value, allowing authenticated users with contributor-level privileges or higher to inject PHP objects. The plugin lacks an internal POP chain, but exploitation is possible if a gadget chain is available via other plugins or themes on the target system. This can lead to arbitrary file deletion, sensitive data disclosure, or remote code execution. The CVSS v3.1 base score is 8.8, reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. No patch or official fix has been published as of the data provided.
Potential Impact
An attacker with contributor-level or higher access can exploit this vulnerability to inject PHP objects through deserialization. Without an internal POP chain, direct exploitation is limited, but if other plugins or themes provide a suitable POP chain, the attacker could achieve critical impacts including arbitrary file deletion, sensitive data retrieval, or remote code execution. This elevates the risk to the confidentiality, integrity, and availability of the affected WordPress site.
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 review installed plugins and themes for potential gadget chains that could be exploited in conjunction with this vulnerability.
