CVE-2023-24498
📋 TL;DR
This vulnerability allows unauthenticated attackers to access a configuration page containing the switch's administrative password in plain text through an unspecified web server endpoint. It affects network switches with vulnerable web interfaces, potentially exposing administrative credentials to unauthorized users.
💻 Affected Systems
- Unspecified network switches
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the switch, enabling network reconfiguration, traffic interception, lateral movement to other systems, and complete network compromise.
Likely Case
Unauthorized users obtain administrative credentials, leading to unauthorized configuration changes, network disruption, or credential reuse attacks against other systems.
If Mitigated
With proper network segmentation and access controls, impact is limited to the affected switch only, preventing lateral movement.
🎯 Exploit Status
Exploitation requires only HTTP access to the vulnerable endpoint. No authentication needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.gov.il/en/Departments/faq/cve_advisories
Restart Required: No
Instructions:
1. Check vendor advisory for specific patch information. 2. Apply firmware updates if available. 3. Verify web interface authentication is properly implemented.
🔧 Temporary Workarounds
Disable web management interface
allDisable the HTTP/HTTPS web server on the switch if not required for management
Switch-specific command to disable web interface
Implement network access controls
allRestrict access to switch management interfaces to trusted IP addresses only
Switch-specific ACL configuration commands
🧯 If You Can't Patch
- Isolate vulnerable switches in separate VLAN with strict access controls
- Implement multi-factor authentication for switch management if supported
- Monitor switch configuration changes and authentication logs
🔍 How to Verify
Check if Vulnerable:
Attempt to access switch web interface endpoints without authentication and check if configuration pages with passwords are accessibleCheck Version:
Switch-specific show version commandVerify Fix Applied:
Verify that all web endpoints require proper authentication and no configuration data is exposed without credentials📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to web endpoints
- Configuration file access logs
- Failed authentication attempts followed by successful configuration access
Network Indicators:
- HTTP requests to unusual endpoints on switch management IP
- Traffic patterns indicating configuration scraping
SIEM Query:
source_ip=* AND dest_ip=switch_management_ip AND http_method=GET AND (uri_contains='config' OR uri_contains='password') AND auth_status='none'
