Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly requires validation and error handling of user-supplied inputs at the web UI to prevent command injection into system calls.
Enforces least privilege on web UI processes to limit the scope and impact of arbitrary code execution on the device.
Monitors system execution for anomalous activities, such as unauthorized system calls from command injection exploits.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
CVE enables exploitation of a public-facing web UI (T1190) via command injection (T1059.004: Unix Shell) for remote code execution.
NVD Description
ALGO 8180 IP Audio Alerter Web UI Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of ALGO 8180 IP Audio Alerter devices. Authentication is required to exploit this vulnerability. The…

specific flaw exists within the web-based user interface. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-28322.
Deeper analysisAI
CVE-2026-0796 is a command injection vulnerability within the web-based user interface of ALGO 8180 IP Audio Alerter devices, enabling remote code execution. The flaw arises from insufficient validation of user-supplied strings before they are used in system calls, as classified under CWE-78. It affects installations of these devices and was published on 2026-01-23 with a CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
An authenticated remote attacker with low privileges can exploit this vulnerability by injecting malicious input into the web UI, leading to arbitrary code execution in the context of the device. Successful exploitation grants high-impact control over confidentiality, integrity, and availability, potentially allowing full compromise of the affected IP audio alerter.
