  • mingyuefusu tushuguanlixitong (library management system)
Versions: All versions up to commit d4836f6b49cd0ac79a4021b15ce99ff7229d4694
Operating Systems: Any OS running the affected software
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the backend admin component at /admin/ path. The vulnerability is in the doFilter function.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing unauthorized access to administrative functions, data theft, or system takeover.

🟠

Likely Case

Unauthorized access to sensitive administrative functions and data within the library management system.

🟢

If Mitigated

Limited impact with proper network segmentation and access controls preventing exploitation attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploit has been publicly disclosed and remote exploitation is possible without authentication.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://gitee.com/mingyuefusu/tushuguanlixitong/issues/IBTS25

Restart Required: Yes

Instructions:

1. Check the project repository for updates. 2. Apply any available patches. 3. Restart the application service. 4. Verify the fix is applied.

🔧 Temporary Workarounds

Network Access Restriction

linux

Restrict access to the admin interface to trusted IP addresses only

# Example firewall rule (adjust for your environment)
iptables -A INPUT -p tcp --dport [APP_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [APP_PORT] -j DROP

Authentication Layer

all

Add additional authentication layer (like reverse proxy with auth) in front of the admin interface

# Configure web server (nginx/apache) with additional authentication
# Example nginx basic auth:
location /admin/ {
    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/.htpasswd;
    proxy_pass http://localhost:[APP_PORT];
}

🧯 If You Can't Patch

  • Isolate the system from internet access and restrict to internal network only
  • Implement strict network segmentation and monitor all access to the admin interface

🔍 How to Verify

Check if Vulnerable:

Check if your system is running a version with commit hash earlier than or equal to d4836f6b49cd0ac79a4021b15ce99ff7229d4694

Check Version:

Check application version or git commit hash in the deployment

Verify Fix Applied:

Test if unauthorized access to admin functions is still possible after applying controls

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts to /admin/ paths
  • Unusual request patterns to admin endpoints
  • Failed authentication attempts followed by successful admin access

Network Indicators:

  • Direct access to admin interface from untrusted sources
  • Unusual traffic patterns to admin endpoints

SIEM Query:

source="web_logs" AND (uri="/admin/*" OR uri CONTAINS "/admin/") AND (user="anonymous" OR auth_status="failed")
