CVE-2024-13889 Details
Description
The WordPress Importer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.8.3 via deserialization of untrusted input in the 'maybe_unserialize' function. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
A PHP Object Injection vulnerability has been identified in the WordPress Importer plugin, affecting all versions through 0.8.3. The issue arises from the deserialization of untrusted input in the 'maybe_unserialize' function. This vulnerability allows authenticated attackers with Administrator-level access to inject a PHP object. However, no known Property-Oriented Programming (POP) chain exists within the vulnerable software itself. The vulnerability could be exploited if an additional plugin or theme containing a POP chain is installed on the same site, potentially allowing the attacker to delete arbitrary files, access sensitive data, or execute code, depending on the nature of the POP chain.
Users are advised to update the WordPress Importer plugin to version 0.8.4 or later, where this vulnerability has been patched.
