💻 Affected Systems
- Servision products
📦 What is this software?
Ivg Webmax by Servision
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing unauthorized access to all data, administrative functions, and potential lateral movement within the network.
Likely Case
Unauthorized access to sensitive information, configuration data, and potential privilege escalation within the affected Servision system.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring in place.
🎯 Exploit Status
Authentication bypass vulnerabilities typically have low exploitation complexity once the bypass method is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://www.gov.il/en/Departments/faq/cve_advisories
Restart Required: No
Instructions:
1. Check the vendor advisory for specific patch information. 2. Apply any available updates from Servision. 3. Verify authentication mechanisms are functioning correctly post-update.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Servision systems to authorized IP addresses only
Multi-Factor Authentication
allImplement additional authentication factors beyond the vulnerable mechanism
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Servision systems
- Enable comprehensive logging and monitoring for authentication attempts
🔍 How to Verify
Check if Vulnerable:
Review authentication logs for unusual patterns or successful logins without proper credentialsCheck Version:
Check Servision documentation for version identification commandsVerify Fix Applied:
Test authentication mechanisms thoroughly after applying any updates or workarounds📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful access
- Authentication from unusual IP addresses
- Multiple authentication attempts in short timeframes
Network Indicators:
- Unusual traffic patterns to authentication endpoints
- Authentication requests bypassing normal flows
