Wecodex Hotel CMS 1.0 (SQL Injection) über Admin-Login

An attacker exploiting CVE-2018-25195 can bypass the authentication mechanism of the Wecodex Hotel CMS admin panel. By injecting malicious SQL code through the username parameter in POST requests to index.php with action=processlogin, an attacker can manipulate database queries. This manipulation can lead to the extraction of sensitive database information, including user credentials, customer data, and potentially financial records. Successful exploitation could also grant the attacker unauthorized administrative access, allowing them to modify system configurations, add or delete users, and compromise the entire system. The blast radius extends to all data stored within the Hotel CMS database.

Hotels and hospitality businesses utilizing Wecodex Hotel CMS version 1.0 are at direct risk. Specifically, those with publicly accessible instances of the CMS and those lacking robust input validation practices are particularly vulnerable. Shared hosting environments where multiple websites share the same server resources are also at increased risk, as a compromise of one website could potentially lead to the compromise of others.

• php: Examine access logs for POST requests to index.php?action=processlogin containing unusual characters or SQL keywords in the username parameter.

 grep -i 'SELECT|UNION|INSERT|DELETE|UPDATE' /var/log/apache2/access.log | grep 'index.php?action=processlogin'

• generic web: Use curl to test the login endpoint with various SQL injection payloads in the username parameter and observe the response for errors or unexpected behavior.

curl -X POST -d "username='; DROP TABLE users;--&password=password" http://your-hotel-cms/index.php?action=processlogin

• database (mysql): If database access is possible, check for unauthorized user accounts or modified database schemas that could indicate compromise.

The primary mitigation for CVE-2018-25195 is to upgrade to a patched version of Wecodex Hotel CMS. Unfortunately, no specific fixed version is listed. If upgrading is not immediately feasible, consider implementing temporary workarounds. Input validation on the username field is essential; strictly limit the allowed characters and length. A Web Application Firewall (WAF) configured to detect and block SQL injection attempts targeting the index.php endpoint can provide an additional layer of defense. Monitor login attempts for suspicious patterns and unusual SQL queries. Sigma or YARA rules can be developed to detect malicious payloads targeting the username parameter. After applying mitigation, verify the fix by attempting a login with a deliberately crafted SQL injection payload; it should be blocked.
