How to fix or mitigate CVE-2026-27179?

Within 24 hours: Identify all MajorDoMo instances in your environment and isolate them from untrusted networks; implement Web Application Firewall (WAF) rules to block SQL injection patterns in the 'parent' parameter. Within 7 days: Disable the commands_search.inc.php module if not essential to operations; conduct database access logs review for unauthorized query activity. Within 30 days: Migrate to an alternative solution or implement comprehensive input validation and parameterized query rewrite if internal development is available; establish ongoing monitoring for MajorDoMo security updates.

AnalysisAIv1 – Mar 12, 2026

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 · show details

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

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.

Executive ViewAI

Why It Matters

MajorDoMo installations are vulnerable to unauthenticated SQL injection attacks that allow attackers to read, modify, or delete database contents without credentials. This critical exposure affects any organization using MajorDoMo for home automation or related functions, with active exploit code publicly available and no vendor patch currently available.

Business Impact: Severe

Compensating Controls

Deploy WAF rules to block SQL injection patterns in GET parameter 'parent' (e.g., blocking single quotes, UNION, SELECT keywords); disable or restrict network access to commands_search.inc.php module; implement network segmentation to limit MajorDoMo accessibility; enable detailed SQL query logging and alerting; consider disabling the vulnerable commands module entirely if functionality permits.
