Who should care

Organizations running Ultimate Project Manager CRM PRO 2.0.5; security teams monitoring for credential exposure risks; developers maintaining PHP-based CRM applications

Technical summary

The /frontend/get_article_suggestion/ endpoint in Ultimate Project Manager CRM PRO 2.0.5 fails to properly sanitize user-supplied search parameters, resulting in a blind SQL injection vulnerability. Attackers with low privileges can craft malicious requests using boolean-based inference techniques to extract usernames and password hashes from the tbl_users database table. The vulnerability is exploitable over the network with low attack complexity, requiring no user interaction. The CVSS 4.0 score of 7.1 reflects high confidentiality impact with limited integrity impact.

Defensive priority

HIGH

Recommended defensive actions

• Apply vendor patches or upgrade to a non-vulnerable version of Ultimate Project Manager CRM PRO if available
• Implement parameterized queries and prepared statements for all database interactions
• Apply principle of least privilege to database accounts used by the application
• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in the /frontend/get_article_suggestion/ endpoint
• Monitor application logs for anomalous query patterns and repeated boolean-based inference attempts
• Rotate credentials for all users in tbl_users table if compromise is suspected
• Conduct code review of search parameter handling in frontend endpoints to identify similar vulnerabilities
