CVE-2009-2143
At a glance
CVE-2009-2143 is a critical-severity Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in the firestats WordPress plugin, affecting versions < 1.6.2. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.6.2; sites on affected versions should update now. Disclosed June 2009, reported by darkmasking.
Vulnerability Overview
PHP remote file inclusion vulnerability in firestats-wordpress.php in the FireStats plugin before 1.6.2-stable for WordPress allows remote attackers to execute arbitrary PHP code via a URL in the fs_javascript parameter.
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-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Reaching this weakness in firestats < 1.6.2 takes a caller who can reach the endpoint. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.
Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For firestats the fix is 1.6.2: builds < 1.6.2 are affected, anything from 1.6.2 onward is not.
Remediation
Update to version 1.6.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to firestats: 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. None of that substitutes for the fix: firestats 1.6.2 closes this, and updating the plugin is the step that ends it.
