Executive brief
The Ashtanga theme for WordPress is vulnerable to a security flaw that allows unauthorized users to inject malicious code. This could lead to a complete takeover of the website, theft of customer data, or a total service outage. Site owners should update to version 1.3 immediately to prevent potential mass-exploitation campaigns.
Technical details
A PHP Object Injection vulnerability exists in the Ashtanga theme for WordPress (versions <= 1.2) due to the improper deserialization of untrusted data (CWE-502). An unauthenticated remote attacker can exploit this by sending specially crafted input to the application. If a suitable Property-Oriented Programming (POP) chain is present on the server, this can lead to arbitrary code execution, SQL injection, or file system traversal. The vulnerability is addressed in version 1.3.
