Overview
The cybersecurity world is continuously on the hunt for potential vulnerabilities that could compromise the integrity, confidentiality, and availability of systems. One such vulnerability, identified as CVE-2025-32603, has been recently discovered in HK WP Online Users Stats, a common WordPress plugin. This vulnerability is a significant concern as it allows malicious actors to perform Blind SQL Injection attacks, potentially leading to system compromise or data leakage. The severity of this vulnerability underscores the need for prompt action from the community, system administrators, and developers.

HK WP Online Users Stats | n/a – 1.0.0
How the Exploit Works
The vulnerability stems from the improper neutralization of special elements used in an SQL command. Essentially, the HK WP Online Users Stats plugin fails to correctly sanitize user inputs that are included in SQL queries. This allows a malicious user to manipulate the syntax of the SQL query to their advantage and perform a Blind SQL Injection attack.
In a Blind SQL Injection, the attacker can exploit the SQL vulnerability to insert malicious SQL statements into an entry field for execution, often leading to unauthorized viewing of user lists, deletion of tables, or access to other parts of the database they would not normally have access to.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. In this case, the malicious SQL statement is embedded within the input data.
POST /wp_stats/update HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
user_id=1'; DROP TABLE users; --In this example, the attacker is attempting to delete the “users” table from the database. The ‘–‘ at the end of the payload is a comment symbol in SQL, which effectively ignores the rest of the original query, allowing the attacker’s malicious query to execute instead.
Mitigation and Recommendations
In response to the identification of this vulnerability, immediate mitigation actions should be taken. The primary recommendation is to apply the vendor patch once it is made available. Until then, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation.
In addition to these steps, it is also recommended to follow best coding practices, including the use of parameterized queries or prepared statements, which can help prevent SQL Injection attacks. Regularly reviewing and updating cybersecurity measures can also help to protect against such vulnerabilities.
