How the Exploit Works

The exploit works by an attacker injecting malicious SQL commands into the application’s database query. Since WP Guru Error Log Viewer improperly neutralizes special elements used in an SQL command, an attacker can manipulate the application’s database, potentially giving them access to sensitive information, or allowing them to manipulate or delete data. This kind of attack is known as Blind SQL Injection because the attacker doesn’t need to see the database’s output to exploit it.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This example represents a malicious HTTP request:

POST /error-log-viewer/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
id=1' AND (SELECT 1 FROM(SELECT COUNT(*),CONCAT((SELECT (SELECT CONCAT(username,0x7e,password)) FROM wp_users LIMIT 1),FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.PLUGINS GROUP BY x)a) AND '1'='1

In the example, the ‘id’ parameter in the POST request is being manipulated to execute arbitrary SQL commands to extract sensitive data, like user credentials, from the database.

Mitigation

The recommended mitigation strategy for CVE-2025-32681 is to apply the vendor patch as soon as it becomes available. Until the patch is available, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation strategy to detect and block SQL Injection attempts. Regularly updating and patching software, along with implementing robust security measures like WAF or IDS, can significantly reduce the risk of exploitation.
