CVE-2026-0783 is an OS command injection vulnerability identified in the ALGO 8180 IP Audio Alerter, specifically in version 5.5 of its web-based user interface. The vulnerability stems from improper neutralization of special elements in user-supplied input before it is passed to system calls, classified under CWE-78. An authenticated attacker can exploit this flaw by injecting malicious commands through the web UI, resulting in remote code execution with the privileges of the device's operating environment. This can lead to full compromise of the device, allowing attackers to manipulate audio alerts, disrupt communications, or pivot into internal networks. The vulnerability has a CVSS 3.0 base score of 7.2, indicating high severity, with attack vector as network, low attack complexity, requiring privileges but no user interaction, and impacts on confidentiality, integrity, and availability. Although no exploits are currently known in the wild, the presence of authentication requirement somewhat limits immediate risk but does not eliminate it, especially in environments with weak credential management or exposed management interfaces. The ALGO 8180 is commonly used in public safety and enterprise environments for IP-based audio alerting, making the vulnerability particularly concerning for organizations relying on these systems for critical communications.

For European organizations, exploitation of CVE-2026-0783 could result in unauthorized control over IP audio alerting devices, potentially disrupting emergency notifications, public announcements, or internal communications. This could lead to misinformation, failure to alert during emergencies, or unauthorized audio broadcasts, impacting public safety and operational continuity. Confidentiality is at risk as attackers could gain access to device configurations and network information. Integrity is compromised as attackers can alter alert messages or device behavior. Availability could be affected if devices are rendered inoperative or used as footholds for further network intrusion. Organizations in sectors such as public safety, transportation, government, and large enterprises using ALGO 8180 devices are particularly vulnerable. The requirement for authentication reduces risk from external attackers but insider threats or credential compromise could facilitate exploitation. The lack of known exploits currently provides a window for mitigation before widespread attacks occur.

Organizations should immediately inventory ALGO 8180 IP Audio Alerter devices and verify firmware versions, prioritizing those running version 5.5. Although no official patch links are currently available, monitoring ALGO vendor communications for patches or updates is critical. In the interim, restrict administrative access to the web UI by implementing network segmentation, VPN access, or IP whitelisting to limit exposure. Enforce strong authentication policies, including complex passwords and multi-factor authentication where supported, to reduce risk of credential compromise. Regularly audit device logs for unusual commands or access patterns indicative of exploitation attempts. Consider deploying network intrusion detection systems with signatures tuned for command injection attempts targeting these devices. If possible, disable or limit unnecessary web UI functionality to reduce attack surface. Establish incident response plans specific to IP audio alerting systems to quickly address potential compromises. Engage with ALGO support for guidance and timely updates.
