CVE-2022-25787
📋 TL;DR
This vulnerability in Secomea GateManager's LMM API allows system administrators to hijack connections by exposing sensitive information through query strings in GET requests. It affects all versions prior to 9.7, potentially compromising the integrity of remote management connections.
💻 Affected Systems
- Secomea GateManager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with system administrator access could hijack legitimate connections, intercept sensitive data, or gain unauthorized control over managed devices.
Likely Case
Privileged insiders or compromised admin accounts could exploit this to bypass security controls and access restricted systems.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized administrators who would already have significant system access.
🎯 Exploit Status
Exploitation requires system administrator credentials; the vulnerability itself involves simple manipulation of query strings.

🔧 Temporary Workarounds
Restrict API Access
allLimit access to the LMM API to only trusted networks and administrators.
Configure firewall rules to restrict access to GateManager API endpoints
Enhanced Monitoring
allImplement detailed logging and alerting for LMM API access patterns.
Enable verbose logging for API requests and monitor for unusual query string patterns
🧯 If You Can't Patch
- Implement strict network segmentation to isolate GateManager from untrusted networks
- Enforce multi-factor authentication for all administrator accounts
🔍 How to Verify
Check if Vulnerable:
Check GateManager version via web interface or command line; if version is below 9.7, system is vulnerable.Check Version:
Check web interface dashboard or run 'cat /etc/gatemanager/version' on Linux systemsVerify Fix Applied:
Confirm version is 9.7 or higher and test that sensitive information is no longer exposed in query strings.📡 Detection & Monitoring
