CVE-2026-0780

8.8 HIGH

📋 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 user input fields. Organizations using ALGO 8180 devices with web UI access are affected.

💻 Affected Systems

Products:
  • ALGO 8180 IP Audio Alerter
Versions: All versions prior to patch
Operating Systems: Embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Requires web UI access with valid credentials. Default credentials increase risk.

📦 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 DDoS attacks.

🟠

Likely Case

Attackers gain administrative control of devices to modify configurations, disable alerting functions, or use devices as footholds for network reconnaissance.

🟢

If Mitigated

Limited impact due to network segmentation, strong authentication controls, and minimal device privileges.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Authentication required but exploit is straightforward once credentials are obtained. ZDI advisory suggests weaponization is likely.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific version

Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-26-002/

Restart Required: Yes

Instructions:

1. Contact ALGO vendor for security patch
2. Download firmware update
3. Backup device configuration
4. Apply firmware update via web UI
5. Restart device
6. Verify patch installation

🔧 Temporary Workarounds

Network Segmentation

all

Isolate ALGO devices from internet and restrict access to management interfaces

Authentication Hardening

all

Implement strong passwords, multi-factor authentication, and account lockout policies

🧯 If You Can't Patch

  • Disable web UI access entirely if not required
  • 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

Verify Fix Applied:

Verify firmware version matches patched version. Test command injection attempts are properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in system logs
  • Multiple failed authentication attempts followed by successful login
  • Web UI access from unexpected IP addresses

Network Indicators:

  • Unusual outbound connections from ALGO devices
  • Traffic to known malicious IPs
  • Unexpected port scans originating from device

SIEM Query:

source="algo-8180" AND (event_type="command_execution" OR auth_failure>3)
