CVE-2024-8353: 
WordPress vulnerability analysis and mitigation

CVE-2024-8353 affects the GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress in versions up to and including 3.16.1. The vulnerability is a PHP Object Injection flaw that occurs through deserialization of untrusted input via several parameters like 'givetitle' and 'cardaddress'. This critical vulnerability has been assigned a CVSS v3.1 score of 10.0, indicating the highest severity level (NVD, SecurityOnline).

The vulnerability stems from improper handling of untrusted input during the deserialization process. The presence of stripslashesdeep on userinfo allows attackers to bypass the is_serialized check, making it similar to CVE-2024-5932 but with a different exploitation method. The vulnerability is classified as CWE-502 (Deserialization of Untrusted Data) and affects over 100,000 active WordPress installations (NVD, SecurityOnline).

The vulnerability allows unauthenticated attackers to inject malicious PHP objects into the system. When combined with a POP (Property Oriented Programming) chain, attackers can delete arbitrary files and achieve remote code execution on the target website, potentially leading to complete website compromise (SecurityOnline).

Website administrators are strongly advised to update to GiveWP version 3.16.2 or later, which contains the necessary patches to address the vulnerability. The issue was partially patched in version 3.16.1, but additional hardening was implemented in version 3.16.2 for complete mitigation (ASEC).
