Mitigating Controls (NIST 800-53 r5)AI
Directly mandates validation of user-supplied inputs before processing, addressing the lack of proper validation that enables command injection in the Web UI.
Requires timely remediation of identified flaws like this command injection vulnerability through patching or updates.
Restricts the types, length, and format of information inputs to block malicious strings used in command injection attacks.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Command injection vulnerability in web-based UI enables remote code execution on network-accessible device, directly facilitating exploitation of public-facing application.
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-28290.
Deeper analysisAI
CVE-2026-0781 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, allowing arbitrary code execution in the context of the device. Published on 2026-01-23, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-78 (OS Command Injection). It was originally tracked as ZDI-CAN-28290.
Remote attackers with valid authentication credentials (low privileges required) can exploit this vulnerability over the network with low complexity and no user interaction. By injecting a malicious string via the Web UI, they can execute arbitrary code on the affected device, achieving high impacts on confidentiality, integrity, and availability.
