CVE-2026-0787
📋 TL;DR
CVE-2026-0787 is a command injection vulnerability in ALGO 8180 IP Audio Alerter devices that allows unauthenticated remote attackers to execute arbitrary code. The vulnerability exists in the SAC module where user input isn't properly validated before being used in system calls. All organizations using affected ALGO 8180 devices are at risk.
💻 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, disrupt emergency alert systems, or use devices as botnet nodes.
Likely Case
Attackers gain shell access to execute commands, potentially disrupting audio alert functionality, exfiltrating data, or using the device as a foothold for further attacks.
If Mitigated
Limited impact if devices are isolated in protected network segments with strict firewall rules and monitored for unusual activity.
🎯 Exploit Status
ZDI-CAN-28296 suggests this was discovered through coordinated disclosure. The unauthenticated nature and command injection vulnerability make weaponization highly likely.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check vendor advisory
Vendor Advisory: Not provided in references
Restart Required: Yes
Instructions:
1. Contact ALGO vendor for security advisory and patch. 2. Apply firmware update when available. 3. Restart devices after patching. 4. Verify patch effectiveness.
🔧 Temporary Workarounds
Network Segmentation
allIsolate ALGO 8180 devices in separate VLAN with strict firewall rules limiting access to necessary ports only.
Access Control Lists
allImplement network ACLs to restrict access to ALGO 8180 devices to authorized management IP addresses only.
🧯 If You Can't Patch
- Immediately remove internet-facing exposure by placing devices behind firewalls with strict inbound rules
- Implement network monitoring and IDS/IPS rules to detect and block exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vendor advisory. If version is older than patched version, device is vulnerable.Check Version:
Check device web interface or console for firmware version information (specific command depends on device access method)Verify Fix Applied:
After applying vendor patch, verify firmware version matches patched version and test SAC module functionality.📡 Detection & Monitoring
