DescriptionCVE.org

MajorDoMo (aka Major Domestic Module) contains an unauthenticated SQL injection vulnerability in the commands module. The commands_search.inc.php file directly interpolates the $_GET['parent'] parameter into multiple SQL queries without sanitization or parameterized queries. The commands module is loadable without authentication via the /objects/?module=commands endpoint, which includes arbitrary modules by name and calls their usual() method. Time-based blind SQL injection is exploitable using UNION SELECT SLEEP() syntax. Because MajorDoMo stores admin passwords as unsalted MD5 hashes in the users table, successful exploitation enables extraction of credentials and subsequent admin panel access.

AnalysisAI

Unauthenticated SQL injection in MajorDoMo's commands module allows remote attackers to extract database contents including unsalted MD5 password hashes without authentication, enabling credential compromise and admin panel access. The vulnerability stems from unsanitized $_GET parameters in SQL queries accessible via the /objects/?module=commands endpoint, and public exploit code is available. Affected versions lack a patch and impact both MajorDoMo and PHP installations running this software.

Technical ContextAI

Classified as CWE-89 (SQL Injection). Affects the commands component of Majordomo.
