Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects the e107 content management system, specifically how it handles logins through certain authentication plugins. If configured with an external database, an attacker could potentially access or alter data within that database. The main concern is to confirm if this specific plugin and configuration are in use within our environment.
- SQL injection in login process.
- Potential data exposure or modification.
- Confirm if this CMS is in use.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending specially crafted login requests to a vulnerable e107 CMS. If the alt_auth plugin is installed and configured to use an external database for authentication, the attacker can inject malicious SQL code into the username field. This injection occurs because the system directly interpolates the username into SQL queries without adequate sanitization before execution.
- Unauthenticated access to a configured login endpoint.
- Usernames submitted to alt_auth plugin.
- Data exposure, modification, or query disclosure.
Live Threat
Current exploitation, exposure, and threat context
When the alt_auth plugin is installed and configured with an external database, an unauthenticated user could inject SQL into the login username field. This could allow an attacker to expose or modify data accessible by the database account or reveal generated queries.
- Database data could be exposed.
- SQL injection via login username.
- Unauthorized data access or modification.
Operational Fix
Recommended remediation, mitigation, and detection steps
Application owners and platform teams are likely responsible for addressing this vulnerability in the e107 content management system, particularly if the alt_auth plugin is configured with an external database. The immediate priority is to identify all instances of e107 with the vulnerable plugin and assess their exposure to external access and business criticality. A coordinated effort will then be needed to plan and execute remediation, involving coordination with any necessary infrastructure or security teams.
- Identify accountable application owners.
- Verify alt_auth plugin configuration and database connections.
- Plan and coordinate phased remediation based on risk.
