CVE-2024-2501: 
WordPress vulnerability analysis and mitigation

The Hubbub Lite – Fast, Reliable Social Sharing Buttons plugin for WordPress contains a PHP Object Injection vulnerability (CVE-2024-2501) affecting all versions up to and including 1.33.1. The vulnerability was discovered and reported by Wordfence, with disclosure on April 9, 2024 (NVD).

The vulnerability exists in the 'dpsp_maybe_unserialize' function which performs deserialization of untrusted input. This vulnerability has been assigned a CVSS v3.1 base score of 7.5 (HIGH) with the vector string CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H. While no POP (Property Oriented Programming) chain is present in the vulnerable plugin itself, the vulnerability could be exploited if a POP chain exists via additional plugins or themes installed on the target system (NVD).

If successfully exploited, this vulnerability could allow authenticated attackers with contributor-level access or higher to inject PHP objects. When combined with a POP chain from other installed components, this could lead to arbitrary file deletion, sensitive data retrieval, or code execution on the affected system (NVD).

The vulnerability requires an authenticated user with at least contributor-level access to exploit. While the attack complexity is considered high, no user interaction is needed once the attacker has the required access (NVD).

Users should update to version 1.33.2 or later of the Hubbub Lite plugin, which contains fixes for this vulnerability (WordPress Plugin).
