📦 What is this software?
Swetrix by Swetrix
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise allowing attacker to execute arbitrary code, steal data, install backdoors, pivot to other systems, and maintain persistent access.
Likely Case
Attacker gains shell access to the server, can read/write sensitive files, and potentially compromise the entire hosting environment.
If Mitigated
Attack is blocked at network perimeter or application firewall; server remains secure with no data loss.
🎯 Exploit Status
The vulnerability is well-documented with technical analysis available, making exploitation straightforward for attackers.

🔧 Temporary Workarounds
Web Application Firewall Rules
allImplement WAF rules to block directory traversal patterns in HTTP requests
# Example mod_security rule: SecRule ARGS "\.\./" "id:1001,phase:2,deny,msg:'Directory Traversal Attempt'
Network Segmentation
linuxRestrict API access to trusted IP addresses only
# Example iptables rule: iptables -A INPUT -p tcp --dport 3000 -s 192.168.1.0/24 -j ACCEPT
# Example iptables rule: iptables -A INPUT -p tcp --dport 3000 -j DROP
🧯 If You Can't Patch
- Implement strict input validation to reject any paths containing '../' sequences
- Run Swetrix in a containerized environment with read-only filesystem for upload directories
🔍 How to Verify
Check if Vulnerable:
Check if your Swetrix version is before commit 7d8b972 by examining the git commit hash or checking the version in package.jsonCheck Version:
git log --oneline -1 | grep 7d8b972 || cat package.json | grep versionVerify Fix Applied:
Verify the commit hash is 7d8b972 or later, and test that directory traversal attempts are properly blocked📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../' patterns in file upload parameters
- Unusual file creation in system directories
- Failed authentication attempts followed by successful file uploads
Network Indicators:
- HTTP POST requests to upload endpoints with encoded directory traversal sequences
- Unusual outbound connections from the Swetrix server
