💻 Affected Systems
- petstore
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining root/administrator access, data exfiltration, and lateral movement within the network.
Likely Case
Unauthorized code execution leading to data theft, service disruption, or deployment of malware/backdoors.
If Mitigated
Limited impact with proper network segmentation and access controls preventing exploitation attempts.
🎯 Exploit Status
Exploitation requires understanding of the DELETE endpoint structure and command injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.0.8 or later
Vendor Advisory: https://github.com/swagger-api/swagger-petstore
Restart Required: No
Instructions:
1. Check current version with 'petstore --version'. 2. Update to v1.0.8+ using package manager or manual installation. 3. Verify fix with version check.
🔧 Temporary Workarounds
Disable DELETE endpoint
LinuxTemporarily disable or block access to the DELETE endpoint until patching is complete.
iptables -A INPUT -p tcp --dport [PORT] -m string --string "DELETE" --algo bm -j DROP
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all DELETE endpoint parameters
- Deploy network-based intrusion prevention system (IPS) rules to block suspicious DELETE requests
🔍 How to Verify
Check if Vulnerable:
Check if petstore version is exactly 1.0.7 using 'petstore --version' or examining package metadata.Check Version:
petstore --versionVerify Fix Applied:
Confirm version is 1.0.8 or higher and test DELETE endpoint with safe payloads to ensure proper input validation.📡 Detection & Monitoring
Log Indicators:
- Unusual DELETE requests with shell metacharacters
- Multiple failed DELETE attempts with suspicious parameters
- System logs showing unexpected process execution
Network Indicators:
- DELETE requests containing command injection patterns (;, |, &, $, etc.)
- Outbound connections from petstore process to unexpected destinations
SIEM Query:
source="petstore.log" AND (method="DELETE" AND (url="*;*" OR url="*|*" OR url="*&*" OR url="*$*"))
