CVE-2026-0795
📋 TL;DR
This vulnerability allows authenticated remote attackers to execute arbitrary system commands on ALGO 8180 IP Audio Alerter devices through the web interface. Attackers can gain full control of affected devices by injecting malicious commands into vulnerable parameters. Organizations using ALGO 8180 devices with web UI access are affected.
💻 Affected Systems
- ALGO 8180 IP Audio Alerter
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attackers to install persistent backdoors, pivot to internal networks, disable safety systems, or use devices for botnet participation.
Likely Case
Attackers with valid credentials execute commands to steal configuration data, modify device settings, or disrupt audio alerting functionality.
If Mitigated
Limited impact due to network segmentation, strong authentication controls, and monitoring preventing successful exploitation.
🎯 Exploit Status
Authentication required but command injection is straightforward once authenticated. ZDI has details but no public exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-26-017/
Restart Required: Yes
Instructions:
1. Contact ALGO vendor for patch. 2. Backup device configuration. 3. Apply firmware update. 4. Restart device. 5. Verify patch applied successfully.
🔧 Temporary Workarounds
Network Segmentation
allIsolate ALGO devices from internet and restrict internal access to management interfaces
Authentication Hardening
allImplement strong unique passwords, MFA if supported, and account lockout policies
🧯 If You Can't Patch
- Disable web UI access if not required for operations
- Implement strict network ACLs allowing only trusted IPs to access management interface
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vendor advisory. Test with controlled command injection if authorized.Check Version:
Check web UI system information page or vendor documentation for version check procedureVerify Fix Applied:
Verify firmware version matches patched version from vendor. Test command injection attempts fail.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed authentication attempts followed by successful login
- Web UI requests with shell metacharacters
