Description
The wpForo Forum plugin for WordPress is vulnerable to error‐based or time-based SQL Injection via the get_members() function in all versions up to, and including, 2.4.8 due to missing integer validation on the 'offset' and 'row_count' parameters. The function blindly interpolates 'row_count' into a 'LIMIT offset,row_count' clause using esc_sql() rather than enforcing numeric values. MySQL 5.x’s grammar allows a 'PROCEDURE ANALYSE' clause immediately after a LIMIT clause. Unauthenticated attackers controlling 'row_count' can append a stored‐procedure call, enabling error‐based or time‐based blind SQL injection that can be used to extract sensitive information from the database.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2025-4203 is a vulnerability in the wpForo Forum WordPress plugin (versions up to and including 2.4.8) where the get_members() function does not properly validate integer parameters 'offset' and 'row_count'. This allows unauthenticated attackers to perform error-based or time-based SQL Injection by manipulating the 'row_count' parameter, which is interpolated directly into a SQL LIMIT clause. Because MySQL 5.x allows a PROCEDURE ANALYSE clause after LIMIT, attackers can append stored procedure calls to extract sensitive database information without authentication.

Impact Analysis

This vulnerability can allow unauthenticated attackers to extract sensitive information from your database by exploiting SQL Injection in the wpForo plugin. This can lead to data leakage, exposing user data or other confidential information stored in the forum's database. Since the attack requires no authentication, it poses a significant security risk to the integrity and confidentiality of your forum data.

Compliance Impact

This vulnerability can negatively impact compliance with data protection regulations such as GDPR and HIPAA because it allows unauthorized access to sensitive personal data stored in the forum's database. Exploitation could lead to data breaches, violating requirements for protecting personal information and potentially resulting in legal and financial penalties.

Detection Guidance

This vulnerability involves unauthenticated SQL Injection via the 'offset' and 'row_count' parameters in the get_members() function of the wpForo plugin. Detection can involve monitoring HTTP requests to the wpForo plugin endpoints for suspicious parameters, especially those manipulating 'row_count' or 'offset' with non-numeric or unusual values. Since the vulnerability allows appending stored-procedure calls after a LIMIT clause, detection could include inspecting logs or using web application firewall (WAF) rules to identify SQL injection patterns in these parameters. Specific commands are not provided in the resources, but general approaches include using tools like curl or Burp Suite to send crafted requests to the vulnerable endpoints and monitoring for error-based or time-based SQL injection responses. For example, sending requests with 'row_count' parameter set to a value like '1 PROCEDURE ANALYSE()' and observing the response time or error messages could indicate exploitation attempts. [2]

Mitigation Strategies

Immediate mitigation steps include updating the wpForo plugin to version 2.4.9 or later, as this version contains fixes for the SQL Injection vulnerability and other related security issues. After updating, clear all caches, purge any CDN content, and flush Redis Object Cache if used to ensure no cached vulnerable code remains active. Additionally, consider implementing web application firewall (WAF) rules to block suspicious requests targeting the 'offset' and 'row_count' parameters. Monitoring and restricting access to the plugin endpoints can also help reduce risk until the update is applied. [2]
