CVE-2024-35474

6.5 MEDIUM

📋 TL;DR

A directory traversal vulnerability in iceice666 ResourcePack Server allows remote attackers to read arbitrary files on the server by manipulating file paths. This affects all users running versions before v1.0.8. Attackers can potentially access sensitive configuration files or other data stored on the server.

💻 Affected Systems

Products:
  • iceice666 ResourcePack Server
Versions: All versions before v1.0.8
Operating Systems: Any OS running the vulnerable software
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the setPath function in ResourcePackFileServer.kt and affects all default configurations

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at 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 server file system disclosure including sensitive configuration files, credentials, and application source code

🟠

Likely Case

Disclosure of application configuration files and potentially sensitive data stored in accessible directories

🟢

If Mitigated

Limited to non-sensitive file disclosure if proper file permissions and access controls are implemented

🌐 Internet-Facing: HIGH - Remote unauthenticated attackers can exploit this vulnerability
🏢 Internal Only: MEDIUM - Internal attackers could still exploit but with less initial access required

🎯 Exploit Status

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

The vulnerability is simple to exploit via path traversal sequences like '../' in file requests

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v1.0.8

Vendor Advisory: https://gist.github.com/apple502j/e99ca3a00e492bf1c942214b13213b46

Restart Required: Yes

Instructions:

1. Download v1.0.8 or later from the official source
2. Stop the ResourcePack Server service
3. Replace the existing installation with the patched version
4. Restart the ResourcePack Server service

🔧 Temporary Workarounds

Network Access Restriction

linux

Restrict network access to the ResourcePack Server to trusted IP addresses only

iptables -A INPUT -p tcp --dport [RESOURCEPACK_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [RESOURCEPACK_PORT] -j DROP

File System Permissions Hardening

linux

Restrict file system permissions to limit what files can be accessed

chmod 750 /path/to/resourcepack/files
chown root:root /path/to/resourcepack/files

🧯 If You Can't Patch

  • Implement strict network segmentation and firewall rules to limit access to the ResourcePack Server
  • Run the service under a restricted user account with minimal file system permissions

🔍 How to Verify

Check if Vulnerable:

Check if the server responds to path traversal requests like GET /../../etc/passwd or similar

Check Version:

Check the server version in the application logs or configuration files

Verify Fix Applied:

Attempt the same path traversal requests after patching - they should return 404 or access denied errors

📡 Detection & Monitoring

Log Indicators:

  • HTTP requests containing '../' sequences
  • Unusual file access patterns outside expected resource directories
  • 404 errors for system files

Network Indicators:

  • HTTP requests with multiple '../' in the path
  • Requests for known system files like /etc/passwd, /etc/shadow

SIEM Query:

source="resourcepack_logs" AND (uri="*../*" OR status=404 AND uri="*/etc/*")
