A public exploit (EDB-52555) is available on Exploit-DB, which significantly increases the risk to unpatched systems. The vulnerability allows for potential unauthorized access to the database, leading to data breaches or modification. Ghost CMS is a popular open-source platform for creating and managing online publications. The availability of a working exploit makes exploitation easier and more likely.

Attack Chain

  1. Attacker identifies a Ghost CMS 6.19.0 instance.
  2. Attacker crafts a malicious SQL query designed to exploit the SQL injection vulnerability.
  3. Attacker injects the crafted SQL query into a vulnerable parameter or input field of the Ghost CMS application.
  4. The application processes the malicious SQL query without proper sanitization or validation.
  5. The injected SQL query is executed against the underlying database.
  6. The attacker gains unauthorized access to sensitive data stored in the database, such as user credentials, posts, or configuration settings.
  7. The attacker may modify data, create new administrative accounts, or extract sensitive information.

Impact

Successful exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive data stored in the Ghost CMS database. This could include user credentials, content, and potentially system configurations. The impact ranges from data breaches and defacement of the website to complete compromise of the Ghost CMS instance.

Recommendation

  • Upgrade Ghost CMS to a patched version that addresses the SQL injection vulnerability.
  • Deploy the Sigma rules in this brief to your SIEM and tune for your environment.
  • Implement input validation and sanitization measures to prevent SQL injection attacks.
  • Monitor web server logs for suspicious activity and potential SQL injection attempts.
