CVE-2025-7936

6.3 MEDIUM

📋 TL;DR

This critical SQL injection vulnerability in the fuyang_lipengjun platform allows remote attackers to execute arbitrary SQL commands via the beanName/methodName parameters in the ScheduleJobLogController. Affected systems are those running vulnerable versions of this platform, potentially exposing database contents to unauthorized access.

💻 Affected Systems

Products:
  • fuyang_lipengjun platform
Versions: All versions up to commit ca9aceff6902feb7b0b6bf510842aea88430796a
Operating Systems: Any OS running the Java application
Default Config Vulnerable: ⚠️ Yes
Notes: This product uses rolling releases, so specific version numbers are not available. All instances up to the specified commit hash are vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including data exfiltration, data manipulation, privilege escalation, and potential remote code execution through database functions.

🟠

Likely Case

Unauthorized data access and extraction from the application database, potentially exposing sensitive information.

🟢

If Mitigated

Limited impact with proper input validation and parameterized queries in place.

🌐 Internet-Facing: HIGH - The vulnerability can be exploited remotely without authentication, making internet-facing instances particularly vulnerable.
🏢 Internal Only: MEDIUM - Internal systems are still at risk but may have additional network segmentation and access controls.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

The exploit has been publicly disclosed and SQL injection vulnerabilities are commonly weaponized. Attack requires no authentication.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions after commit ca9aceff6902feb7b0b6bf510842aea88430796a

Vendor Advisory: https://gitee.com/fuyang_lipengjun/platform/issues/ICLIK1

Restart Required: Yes

Instructions:

1. Update to the latest version from the repository. 2. Verify the fix is included by checking the commit history. 3. Restart the application server. 4. Test the vulnerable endpoint to ensure SQL injection is no longer possible.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement input validation to reject suspicious characters in beanName/methodName parameters

# Add input validation in ScheduleJobLogController.java
# Example: if (beanName.matches("[^a-zA-Z0-9_]")) { throw new IllegalArgumentException(); }

WAF Rule

all

Deploy web application firewall rules to block SQL injection patterns

# Example ModSecurity rule:
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"

🧯 If You Can't Patch

  • Implement network segmentation to restrict access to the vulnerable endpoint
  • Deploy database monitoring to detect unusual SQL queries and block suspicious connections

🔍 How to Verify

Check if Vulnerable:

Test the /scheduleJobLog/queryPage endpoint with SQL injection payloads in beanName or methodName parameters. If the application returns database errors or unexpected data, it is vulnerable.

Check Version:

git log --oneline -1 # Check the latest commit hash against the vulnerable commit

Verify Fix Applied:

After patching, attempt the same SQL injection tests. The application should reject malicious input or return generic error messages without database details.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in application logs
  • Database error messages containing SQL syntax
  • Multiple failed login attempts or parameter manipulation

Network Indicators:

  • HTTP requests with SQL keywords in parameters (SELECT, UNION, etc.)
  • Unusual database connection patterns from application servers

SIEM Query:

source="application.log" AND ("SQL" OR "database error" OR "syntax error") AND ("beanName" OR "methodName")
