📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise allowing data theft, data destruction, or full system takeover through SQL injection leading to remote code execution.

🟠

Likely Case

Unauthorized access to sensitive data including user credentials, personal information, and administrative data stored in the database.

🟢

If Mitigated

Limited impact with proper input validation and database permissions preventing data exfiltration or system compromise.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploit details have been publicly disclosed in the Gitee issue tracker, making exploitation straightforward for attackers.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://gitee.com/mingyuefusu/tushuguanlixitong/issues/IBTSJL

Restart Required: No

Instructions:

1. Monitor the Gitee repository for patches. 2. Apply any available security updates. 3. Implement input validation and parameterized queries.

🔧 Temporary Workarounds

Web Application Firewall (WAF)

all

Deploy a WAF with SQL injection protection rules to block malicious requests.

Input Validation Filter

all

Implement server-side input validation to sanitize the 'condition' parameter.

🧯 If You Can't Patch

  • Isolate the vulnerable system behind a firewall with strict access controls.
  • Implement database-level protections including least privilege access and query logging.

🔍 How to Verify

Check if Vulnerable:

Test the /admin/bookList endpoint with SQL injection payloads in the 'condition' parameter.

Check Version:

Check the software version against commit hash d4836f6b49cd0ac79a4021b15ce99ff7229d4694

Verify Fix Applied:

Verify that SQL injection attempts no longer succeed and parameterized queries are implemented.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in application logs
  • Multiple failed login attempts from single IP
  • Suspicious parameter values in /admin/bookList requests

Network Indicators:

  • SQL keywords in HTTP GET parameters
  • Unusual database connection patterns
  • Excessive requests to vulnerable endpoint

SIEM Query:

source="web_logs" AND uri="/admin/bookList" AND (param="condition" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR 1=1")
