CVE-2025-7801: BossSoft CRM SQL Injection Vulnerability

CVE-2025-7801 Overview

A critical SQL injection vulnerability has been discovered in BossSoft CRM version 6.0. The vulnerability exists in the /crm/module/HNDCBas_customPrmSearchDtl.jsp file, where improper handling of the cstid parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or further system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete database contents, potentially compromising customer data and business-critical information stored in the CRM system.

Technical Details for CVE-2025-7801

Vulnerability Analysis

This vulnerability is classified as an injection flaw (CWE-74), specifically manifesting as SQL injection in a JSP-based web application. The vulnerable endpoint /crm/module/HNDCBas_customPrmSearchDtl.jsp accepts the cstid parameter without proper input validation or parameterized query implementation. When user-supplied input is directly concatenated into SQL queries, attackers can manipulate the query logic to access unauthorized data or perform malicious database operations.

The exploit for this vulnerability has been publicly disclosed, increasing the urgency for organizations using BossSoft CRM 6.0 to take immediate protective measures. The network-accessible attack vector means no local system access is required, making this vulnerability particularly dangerous in internet-facing deployments.

Root Cause

The root cause of this vulnerability is the lack of proper input sanitization and the absence of parameterized queries (prepared statements) in the HNDCBas_customPrmSearchDtl.jsp file. The cstid parameter is directly incorporated into SQL queries without validation, allowing attackers to inject arbitrary SQL commands. This represents a fundamental secure coding oversight where user input is trusted and processed without adequate security controls.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the vulnerable JSP endpoint, manipulating the cstid parameter to include SQL injection payloads. This could enable various attack scenarios including:

• Data Extraction: Using UNION-based or blind SQL injection techniques to extract sensitive customer data, credentials, or business information from the database.
• Data Manipulation: Modifying or deleting database records to disrupt business operations or cover attack traces.
• Privilege Escalation: Potentially accessing administrative accounts or escalating privileges within the CRM system.
• Lateral Movement: Using database access as a pivot point to explore connected systems or extract credentials for further attacks.

The vulnerability is accessible via direct HTTP requests to the vulnerable endpoint, making it exploitable by any attacker with network access to the CRM application.

Detection Methods for CVE-2025-7801

Indicators of Compromise

• Unusual database queries containing SQL injection patterns such as ' OR 1=1--, UNION SELECT, or time-based injection payloads targeting the cstid parameter
• Abnormal HTTP requests to /crm/module/HNDCBas_customPrmSearchDtl.jsp with suspicious parameter values
• Database errors or exceptions in application logs indicating malformed SQL queries
• Unexpected data access patterns or bulk data extraction from customer-related database tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to BossSoft CRM endpoints
• Implement database activity monitoring to identify anomalous query patterns, especially those involving the affected JSP file
• Enable detailed logging for the CRM application and monitor for requests containing common SQL injection payloads
• Use SentinelOne Singularity platform to detect post-exploitation behaviors and lateral movement following successful SQL injection attacks

Monitoring Recommendations

• Configure real-time alerts for suspicious requests to /crm/module/HNDCBas_customPrmSearchDtl.jsp with encoded or special characters in the cstid parameter
• Monitor database server logs for query failures, authentication anomalies, or unexpected data access
• Implement network traffic analysis to detect data exfiltration patterns following potential exploitation

How to Mitigate CVE-2025-7801

Immediate Actions Required

• Restrict network access to the BossSoft CRM application to trusted IP addresses only using firewall rules
• Implement Web Application Firewall (WAF) rules to block SQL injection attempts targeting the cstid parameter
• Review database access logs for signs of previous exploitation attempts
• Consider taking the vulnerable endpoint offline temporarily if not critical for business operations

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations should monitor the VulDB entry and the GitHub CVE issue for updates on remediation guidance from BossSoft. Contact the vendor directly to inquire about security updates for CRM version 6.0.

Workarounds

• Implement input validation on the application layer to reject requests containing SQL injection patterns in the cstid parameter
• Deploy a reverse proxy or WAF with strict SQL injection detection rules in front of the CRM application
• Apply database-level access controls to limit the permissions of the application's database user, reducing the impact of successful injection attacks
• Use network segmentation to isolate the CRM system from critical infrastructure

# Example WAF rule to block SQL injection patterns (ModSecurity)
SecRule ARGS:cstid "@rx (?i:(\bunion\b.*\bselect\b)|('.*(\bor\b|\band\b).*=)|(-{2,})|(/\*.*\*/))" \
    "id:100001,phase:2,deny,status:403,log,msg:'SQL Injection attempt on cstid parameter'"
