CVE-2026-0784 is an OS command injection vulnerability classified under CWE-78 affecting the ALGO 8180 IP Audio Alerter, specifically version 5.5. The flaw resides in the device's web-based user interface where user-supplied input is not properly sanitized before being used in system calls. This improper neutralization allows an authenticated attacker to inject arbitrary OS commands, leading to remote code execution on the device. The vulnerability requires the attacker to have valid credentials, but no additional user interaction is necessary. Exploiting this vulnerability enables attackers to execute code with the privileges of the device’s web interface process, potentially allowing full control over the device, manipulation of audio alerting functions, disruption of communications, and pivoting to other network segments. The vulnerability was assigned a CVSS v3.0 base score of 7.2, indicating high severity with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. No public exploits are known at this time, but the vulnerability was reported by the Zero Day Initiative (ZDI) under identifier ZDI-CAN-28293. The lack of proper input validation in the web UI is the root cause, highlighting the importance of secure coding practices in embedded device management interfaces.

For European organizations, especially those relying on ALGO 8180 IP Audio Alerter devices for critical communication and alerting functions, this vulnerability poses a significant risk. Successful exploitation can lead to unauthorized remote code execution, enabling attackers to disrupt alerting systems, manipulate or disable audio notifications, and potentially gain a foothold within the internal network. This can compromise operational continuity in environments such as public safety, transportation hubs, corporate campuses, and industrial facilities. Confidentiality of sensitive alerting configurations and integrity of alert messages can be undermined, while availability of critical communication channels may be disrupted. Given the device’s role in physical security and emergency notification, exploitation could have cascading effects on safety and incident response. The requirement for authentication limits exposure but does not eliminate risk, particularly if credential management is weak or if attackers gain access through phishing or lateral movement. The absence of known exploits currently reduces immediate threat but does not preclude future active exploitation.

1. Apply vendor patches or firmware updates as soon as they become available to address the vulnerability directly. 2. Restrict access to the ALGO 8180 IP Audio Alerter management interface by implementing network segmentation and firewall rules limiting access to trusted administrators only. 3. Enforce strong authentication mechanisms, including complex passwords and multi-factor authentication, to reduce the risk of credential compromise. 4. Monitor device logs and network traffic for unusual activity indicative of attempted exploitation or unauthorized access. 5. Implement input validation and sanitization controls where possible, especially if custom integrations or scripts interact with the device. 6. Conduct regular security assessments and penetration testing on critical communication infrastructure to identify and remediate vulnerabilities proactively. 7. Educate administrators on secure device management practices and the risks associated with command injection vulnerabilities. 8. Consider isolating the device on dedicated VLANs or air-gapped networks to minimize attack surface exposure.
