JS Archive List Plugin for WordPress | 6.1.5 and below
How the Exploit Works
The vulnerability stems from the build_sql_where() function in the JS Archive List plugin, which inadequately escapes user-supplied parameters and lacks sufficient preparation on the existing SQL query. This allows an unauthenticated attacker to append malicious SQL queries into existing ones, potentially leading to extraction of sensitive information from the database.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request with a malicious SQL payload.
POST /wp-admin/admin-ajax.php?action=jsal_suggest HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
s=1+UNION+SELECT+1,CONCAT(user_login,0x3a,user_pass),1+FROM+wp_users-- -In this example, the “s” parameter is used to inject a SQL UNION SELECT query that concatenates the login and password of users from the ‘wp_users’ table. This could potentially leak sensitive information like usernames and hashed passwords.
Mitigation Guidance
Users of the JS Archive List Plugin for WordPress are strongly advised to apply the vendor patch to rectify this vulnerability. In the absence of a patch, users can also deploy Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary mitigation measure to detect and block SQL Injection attacks. Regularly updating and patching software is also a must to prevent such vulnerabilities.
