CVE-2025-15434
📋 TL;DR
This vulnerability allows remote attackers to execute SQL injection attacks against Yonyou KSOA 9.0 through the /kp/PrintZPYG.jsp file by manipulating the zpjhid parameter. Organizations using Yonyou KSOA 9.0 are affected, particularly those with internet-facing instances. The exploit is publicly available and can be launched remotely without authentication.
💻 Affected Systems
- Yonyou KSOA
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or full system takeover via SQL injection escalation techniques.
Likely Case
Unauthorized data access, extraction of sensitive information, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, WAF protection, and network segmentation preventing exploitation.
🎯 Exploit Status
Public exploit code is available, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Monitor Yonyou vendor channels for updates. Consider workarounds or alternative solutions.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the /kp/PrintZPYG.jsp endpoint and zpjhid parameter.
Access Control Restrictions
allRestrict network access to the vulnerable endpoint using firewall rules or application-level access controls.
🧯 If You Can't Patch
- Isolate vulnerable systems in a segmented network zone with strict access controls.
- Implement comprehensive input validation and parameterized queries at the application level if source code access is available.
🔍 How to Verify
Check if Vulnerable:
Test if /kp/PrintZPYG.jsp is accessible and responds to SQL injection payloads in the zpjhid parameter. Use controlled testing with payloads like ' OR '1'='1.Check Version:
Check Yonyou KSOA version through application interface or configuration files. Specific command depends on deployment method.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented for the zpjhid parameter.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple requests to /kp/PrintZPYG.jsp with suspicious parameters
- Database error messages containing SQL syntax
Network Indicators:
- HTTP requests to /kp/PrintZPYG.jsp containing SQL keywords in parameters
- Unusual database connection patterns from application servers
SIEM Query:
source="web_logs" AND uri="/kp/PrintZPYG.jsp" AND (param="zpjhid" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT")
