At a glance
This record tracks a critical-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Premium Seo Pack WordPress plugin, affecting versions <= 1.8.0. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed May 2015, reported by Evex.
Vulnerability Overview
The AA-Team Premium SEO Pack plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 1.8.0 via the 'file_content' parameter. This makes it possible for unauthenticated attackers that include the default connection key to upload arbitrary files like shell scripts that can be used to execute code on the server. The plugin is also vulnerable to Local File Disclosure via the 'file' parameter. This makes it possible for unauthenticated attackers who include the default connection key to read the contents of arbitrary files on the server, which can contain sensitive information.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-94: Improper Control of Generation of Code ('Code Injection')
Premium Seo Pack <= 1.8.0 carries this weakness at file_content, and reaching it takes a caller who can reach the endpoint. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.
The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. No fixed build of this plugin is recorded for Premium Seo Pack yet, so installs running <= 1.8.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to Premium Seo Pack: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
