CVE-2025-41005: MEMS Events CRM SQL Injection Vulnerability

CVE-2025-41005 Overview

Imaster's MEMS Events CRM contains an SQL injection vulnerability in the keyword parameter within the /memsdemo/exchange_offers.php endpoint. This vulnerability allows attackers to inject malicious SQL queries through user-supplied input, potentially leading to unauthorized database access, data exfiltration, and manipulation of sensitive CRM information.

Critical Impact

SQL injection in a CRM system can expose customer data, financial records, and sensitive business information while potentially allowing attackers to modify or delete critical database contents.

Technical Details for CVE-2025-41005

Vulnerability Analysis

This SQL injection vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command) exists due to insufficient input validation in the keyword parameter of the exchange_offers.php file. When user input is passed to this parameter, the application fails to properly sanitize or parameterize the data before incorporating it into SQL queries, allowing attackers to manipulate database operations.

The vulnerability is exploitable over the network and requires low-privilege authentication to access the affected endpoint. Once exploited, an attacker can potentially read, modify, or delete data from the underlying database, leading to complete compromise of confidentiality, integrity, and availability of the stored information.

Root Cause

The root cause is improper input validation and the absence of parameterized queries or prepared statements in the application's database interaction layer. The keyword parameter accepts user-controlled input that is directly concatenated into SQL query strings without proper sanitization, escaping, or the use of parameterized statements that would prevent SQL injection attacks.

Attack Vector

The attack is conducted over the network by sending crafted HTTP requests to the /memsdemo/exchange_offers.php endpoint with malicious SQL payloads injected into the keyword parameter. An authenticated attacker with low privileges can exploit this vulnerability to execute arbitrary SQL commands against the backend database.

A typical attack scenario involves manipulating the keyword parameter to include SQL syntax that alters the intended query logic. For example, an attacker might inject payload strings containing UNION-based queries to extract data from other tables, boolean-based blind injection techniques to enumerate database contents character by character, or time-based blind injection to infer information through response delays. Technical details and indicators of exploitation can be found in the INCIBE Security Notice.

Detection Methods for CVE-2025-41005

Indicators of Compromise

• Unusual or malformed requests to /memsdemo/exchange_offers.php containing SQL syntax characters such as single quotes, semicolons, UNION keywords, or comment sequences
• Database error messages exposed in HTTP responses indicating query failures from malformed SQL
• Unexpected database queries or data access patterns in database audit logs
• Outbound data exfiltration attempts following access to the vulnerable endpoint

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the keyword parameter
• Monitor web server access logs for requests containing SQL keywords such as SELECT, UNION, INSERT, DELETE, DROP, or comment sequences like -- and /*
• Deploy application-level logging to capture and alert on input validation failures or database query errors
• Utilize intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for all requests to the /memsdemo/exchange_offers.php endpoint
• Configure database activity monitoring to detect unauthorized queries or unusual data access patterns
• Set up alerts for HTTP responses containing database error messages or stack traces
• Regularly review application and database logs for signs of exploitation attempts

How to Mitigate CVE-2025-41005

Immediate Actions Required

• Restrict access to the /memsdemo/exchange_offers.php endpoint until a patch is available
• Deploy WAF rules specifically targeting SQL injection attempts on the keyword parameter
• Review and audit all user inputs reaching the affected endpoint
• Consider temporarily disabling the exchange offers functionality if it is not business-critical

Patch Information

Refer to the vendor for official patch information. Additional details about this vulnerability and related issues in Imaster products can be found in the INCIBE Security Notice.

Workarounds

• Implement input validation to whitelist acceptable characters in the keyword parameter, rejecting any input containing SQL metacharacters
• Deploy parameterized queries or prepared statements at the application level to prevent SQL injection
• Use a Web Application Firewall to filter malicious requests before they reach the application
• Apply the principle of least privilege to database accounts used by the application, limiting the impact of successful exploitation

# Example WAF rule configuration (ModSecurity)
SecRule ARGS:keyword "@rx (?i)(\bunion\b|\bselect\b|\binsert\b|\bdelete\b|\bdrop\b|--|/\*)" \
    "id:100001,phase:2,deny,status:403,msg:'SQL Injection attempt blocked in keyword parameter'"
