Authenticated PHP Code Injection in SoftBB admin/save_opt.php

IdentifiersCVE-2006-4631CWE-94

SoftBB 0.1, and possibly earlier versions, contains a direct static code injection vulnerability in the administrative save_opt.php endpoint. An authenticated remote user can supply arbitrary PHP code through the cache_forum parameter. The application saves this input into info_options.php, which can subsequently be directly requested and executed by the PHP interpreter.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated remote attacker to upload and execute arbitrary PHP code on the server hosting SoftBB, resulting in remote code execution in the privileges of the web-server PHP process.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to admin functionality to trusted users only. Implement input validation and output encoding on all user-supplied data. Consider disabling direct access to files like info_options.php or moving such files outside the web root. Monitor for suspicious activity in the application logs.

Remediation

Patch, then assume compromise.

Upgrade to a version of SoftBB where user input is properly sanitized and validated before being written to PHP files. Ensure that user-supplied data is never directly written to executable files. Apply any available patches from the vendor.
