CVE-2026-73670 Saurus CVE debrief

Who should care

Defenders responsible for CMS installations, especially those using the affected admin/db_data.php file, should assess their exposure and prioritize verification and mitigation efforts.

Why it matters

CVE-2026-73670 is a SQL injection vulnerability in a CMS that allows authenticated administrators to inject arbitrary SQL. Defenders should verify the presence of this vulnerability in their installations, especially if using the affected file, and apply patches or mitigations as available. The vulnerability can lead to database schema enumeration, access to system tables, and potential credential extraction. It requires verification of affected versions and exposure, and implementation of input validation and sanitization to prevent exploitation.

• Potential database schema enumeration by authenticated administrators.
• Possible access to sensitive system tables like information_schema.
• Risk of credential data extraction through chained injection points.
• Need for input validation and sanitization to prevent exploitation.

Technical summary

The SQL injection vulnerability in the admin/db_data.php file of a CMS allows authenticated administrators to inject arbitrary SQL into a SHOW COLUMNS FROM statement. This can be done by supplying unsanitized input through the table_name GET or POST parameter. The vulnerability supports various injection techniques, including table traversal, time-based blind, boolean-based blind, and error-based injection. These techniques can be used to enumerate the full database schema, access system tables such as information_schema, and potentially extract credential data by chaining with secondary injection points.

Defensive priority

Defenders should prioritize verifying the presence of this vulnerability in their CMS installations, especially if they are using the affected admin/db_data.php file, and apply patches or mitigations as available.

Recommended defensive actions

• Verify the presence of the vulnerable file (admin/db_data.php) in your CMS installation.
• Check if your CMS version is affected and apply patches or updates if available.
• Implement input validation and sanitization for the table_name parameter in the admin/db_data.php file.
• Monitor database activity for suspicious queries indicative of SQL injection attempts.
• Perform a thorough review of database schema and access controls to identify potential vulnerabilities.
• Conduct regular security audits to detect and address any new or unpatched vulnerabilities.
• Keep track of vendor advisories and apply patches as soon as they are available.
