Description Preview

A SQL injection vulnerability has been identified in b2evolution CMS version 7.2.3. The vulnerability exists in the User login section where the cfqueryparam parameter is not properly sanitized. This allows malicious actors to inject SQL commands that can be executed by the database, potentially leading to unauthorized access to sensitive data, modification of database content, or execution of administrative operations on the database server. The vulnerability is classified as CWE-89 (SQL Injection) and can be exploited to compromise the affected system.

Overview

The vulnerability affects b2evolution CMS version 7.2.3 and possibly earlier versions. SQL injection occurs when user-supplied data is not properly validated and is included in SQL queries. In this case, the cfqueryparam parameter in the User login section is vulnerable. An attacker can craft special input containing SQL commands that, when processed by the application, will be executed by the database engine. This can lead to unauthorized data access, data manipulation, authentication bypass, and in some cases, server compromise. The vulnerability has been assigned CVE-2021-31632 and is categorized as CWE-89 (SQL Injection).

Remediation

To address this vulnerability, system administrators should take the following actions:

  1. Upgrade to a newer version of b2evolution CMS if a patched version is available.
  2. If upgrading is not immediately possible, implement input validation and sanitization for the cfqueryparam parameter.
  3. Use prepared statements or parameterized queries instead of dynamic SQL construction.
  4. Implement the principle of least privilege for database accounts used by the application.
  5. Consider implementing a Web Application Firewall (WAF) to filter malicious requests.
  6. Regularly monitor logs for suspicious activities that may indicate exploitation attempts.
  7. Apply input validation at all entry points to prevent SQL injection attacks.
