How the Exploit Works
The exploit occurs due to insufficient escaping on a user-supplied parameter and a lack of adequate preparation on an existing SQL query within the getSpace() function of the plugin. By injecting malicious SQL queries via the ‘$id’ variable, an unauthenticated attacker can manipulate the database, potentially extracting sensitive information.
Conceptual Example Code
An example of how the vulnerability might be exploited could be a malicious HTTP request like below:
GET /vulnerable_plugin/getSpace?id=1;DROP TABLE users; HTTP/1.1
Host: target.example.comIn this example, the attacker appends a ‘DROP TABLE’ SQL command to the ‘id’ parameter, which, if successful, would delete the ‘users’ table from the database. This is a simplified example and the actual attacks can be much more complex and damaging.
Mitigation Guidance
Users are advised to apply the latest vendor patch to fix the vulnerability. If a patch is not immediately available, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation. These systems should be configured to detect and prevent SQL Injection attacks.
