CVE-2024-6433
📋 TL;DR
This vulnerability allows attackers to read arbitrary files on the system by providing a crafted path parameter to an application's file zipping functionality. Attackers can exploit this by sending requests with a malicious snapshot_path parameter. Any system running the vulnerable application is affected.
💻 Affected Systems
- Application with vulnerable file zipping functionality
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through reading sensitive files like configuration files, credentials, SSH keys, or database files, potentially leading to lateral movement and data exfiltration.
Likely Case
Unauthorized access to sensitive files containing application configuration, user data, or system information that could enable further attacks.
If Mitigated
Limited impact with proper input validation and file access restrictions in place, potentially only allowing access to non-sensitive files.
🎯 Exploit Status
Exploitation requires sending crafted requests with malicious path parameters to the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: https://huntr.com/bounties/7d0463dd-6373-4eb8-86fc-beac0a1391a5
Restart Required: Yes
Instructions:
1. Identify the vulnerable application version
2. Check vendor advisory for patch availability
3. Apply the security patch
4. Restart the application/service
5. Verify the fix is applied
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to reject path traversal sequences and restrict allowed paths
Implement path validation in application code to reject ../, ..\, and absolute paths
Web Application Firewall Rules
allBlock requests containing path traversal sequences in the snapshot_path parameter
Configure WAF to block requests with ../, ..\, or absolute paths in parameters
🧯 If You Can't Patch
- Implement strict input validation at the application level to sanitize all user-provided paths
- Restrict application permissions using least privilege principle and implement file access controls
🔍 How to Verify
Check if Vulnerable:
Test by sending requests with path traversal sequences (../, ..\) in the snapshot_path parameter and checking if arbitrary files are accessedCheck Version:
Check application version using appropriate method (e.g., version endpoint, package manager)Verify Fix Applied:
Attempt the same path traversal attacks after patching to confirm they are blocked📡 Detection & Monitoring
