CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2024-1813 impacting presstigers simple_job_board. Evaluated with CVSS Base Score of 9.8 (CRITICAL).

Original NVD Description

Source: NIST NVD
The Simple Job Board plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.11.0 via deserialization of untrusted input in the job_board_applicant_list_columns_value function. This makes it possible for unauthenticated attackers to inject a PHP Object. 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 when a submitted job application is viewed.
