CVE-2024-44625
📋 TL;DR
This directory traversal vulnerability in Gogs allows attackers to read, write, or delete arbitrary files on the server by manipulating file paths in edit requests. It affects all Gogs installations running version 0.13.0 or earlier. Attackers can potentially achieve remote code execution by writing malicious files to sensitive locations.
💻 Affected Systems
- Gogs
📦 What is this software?
Gogs by Gogs
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Unauthorized file access and modification, potentially leading to data leakage, service disruption, or privilege escalation.
If Mitigated
Limited impact with proper file system permissions and network segmentation, potentially only allowing file reads in restricted directories.
🎯 Exploit Status
Public technical details and proof-of-concept are available, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.14.0
Vendor Advisory: https://gogs.io/
Restart Required: Yes
Instructions:
1. Backup your Gogs data and configuration. 2. Download Gogs 0.14.0 or later from the official website. 3. Stop the Gogs service. 4. Replace the binary with the new version. 5. Restart the Gogs service. 6. Verify the version is updated.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to Gogs instances to only trusted IP addresses
iptables -A INPUT -p tcp --dport 3000 -s trusted_ip_range -j ACCEPT
iptables -A INPUT -p tcp --dport 3000 -j DROP
File System Hardening
allRun Gogs with minimal file system permissions using containerization or restricted user accounts
docker run -d --name gogs -p 3000:3000 -v /path/to/gogs/data:/data gogs/gogs:latest
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to Gogs instances
- Deploy web application firewall (WAF) rules to detect and block directory traversal patterns
🔍 How to Verify
Check if Vulnerable:
Check the Gogs version by accessing the web interface and viewing the footer, or run: ./gogs --version
Check Version:
./gogs --version
Verify Fix Applied:
Verify the version is 0.14.0 or higher and test file editing functionality with path traversal attempts
📡 Detection & Monitoring
Log Indicators:
- Unusual file path patterns in edit requests
- Failed file operations with path traversal sequences
- Multiple edit requests to non-repository paths
Network Indicators:
- HTTP requests containing '../' sequences in file parameters
- Unusual file write operations to system directories
SIEM Query:
