SQL Injection in CMS via admin/db_data.php Parameter

Publication date: 2026-08-13

Last updated on: 2026-08-13

Assigner: VulnCheck

Description
A CMS contains a SQL injection vulnerability in admin/db_data.php at line 509 that allows authenticated administrators to inject arbitrary SQL into a SHOW COLUMNS FROM statement by supplying unsanitized input through the table_name GET or POST parameter. Attackers can perform table traversal, time-based blind, boolean-based blind, and error-based injection techniques to enumerate full database schema, access system tables such as information_schema, and chain the disclosure with secondary injection points to extract credential data.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2026-73670 is a SQL injection flaw in Saurus CMS Community Edition. It exists in admin/db_data.php at line 509 where the table_name parameter is unsanitized and directly concatenated into a SHOW COLUMNS FROM SQL statement. Authenticated administrators can inject arbitrary SQL commands via GET or POST requests. This enables techniques like table traversal, time-based blind, boolean-based blind, and error-based injection to enumerate database schemas and access sensitive system tables such as information_schema.

Detection Guidance

To detect this SQL injection vulnerability in Saurus CMS, check if the admin/db_data.php file exists and inspect the table_name parameter handling. Use SQL injection testing tools like sqlmap with commands such as: sqlmap -u "http://target.com/admin/db_data.php?table_name=*" --batch --dbs. Alternatively, manually test with payloads like table_name=information_schema.tables or table_name=users' AND SLEEP(5)--.

Impact Analysis

This vulnerability allows attackers with admin credentials to extract sensitive data from the database, including credential information. They can enumerate the full database schema, access system tables, and chain additional injections to perform unauthorized data retrieval or manipulation. The impact includes potential data breaches, unauthorized access to sensitive information, and further compromise of the system.

Compliance Impact

This vulnerability can lead to unauthorized access and exposure of sensitive data, which may violate compliance requirements under GDPR and HIPAA. GDPR mandates protection of personal data, and unauthorized access could result in data breaches requiring notification and potential fines. HIPAA requires safeguarding protected health information, and a breach could lead to penalties and loss of trust.

Mitigation Strategies

Immediately update Saurus CMS to the latest version beyond commit d886e5b. As a temporary fix, restrict access to admin/db_data.php to trusted IPs and enforce strict input validation for the table_name parameter. Disable admin accounts not in use and monitor database queries for suspicious activity.
