What is CVE-2024-10957?
CVE-2024-10957 is a high-severity unsafe deserialization vulnerability in davidanderson UpdraftPlus: WP Backup & Migration Plugin, published on 4 Jan 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to PHP Object Injection in all versions from 1.23.8 to 1.24.11 via deserialization of untrusted input in the 'recursive_unserialized_replace' function. This makes it possible for unauthenticated attackers 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. An administrator must perform a search and replace action to trigger the exploit.
Weakness: CWE-502
