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.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-108900 is an unauthenticated SQL injection vulnerability in Exponent CMS versions up to 3.0.2patch2. The flaw exists in the userLogin function of the xmlrpc.php file when the USE_XMLRPC feature is enabled. Attackers can exploit this by sending malicious XML-RPC method calls like metaWeblog.getUsersBlogs or blogger.getUsersBlogs to inject SQL code directly into the database query.

Detection Guidance

Check if USE_XMLRPC is enabled in Exponent CMS configuration. Monitor xmlrpc.php for unusual requests or SQL errors. Test with XML-RPC methods like metaWeblog.getUsersBlogs or blogger.getUsersBlogs using crafted input to observe SQL behavior.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary SQL commands on the database. Potential impacts include unauthorized data access, data manipulation or deletion, account takeover, and probing of sensitive information. Attackers do not need authentication to exploit this issue if USE_XMLRPC is enabled.

Compliance Impact

This SQL injection vulnerability could lead to unauthorized access or exposure of personal data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using vulnerable Exponent CMS versions may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Disable USE_XMLRPC in Exponent CMS settings. Block or restrict access to xmlrpc.php via firewall or web server rules. Update Exponent CMS to the latest version if a patch is available. Monitor database logs for suspicious queries.
