CVE-2026-0783
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedALGO 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-28292.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceALGO 8180 IP Audio Alerter devices contain a command injection vulnerability in the web-based user interface. The flaw results from insufficient validation of user-supplied input before passing it to a system call. An authenticated attacker can exploit this to execute arbitrary code in the context of the device's operating system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelLocate the physical device or check network inventory for ALGO 8180 IP Audio Alerter hardware. Confirm the device is the specific model in scope.Affected if The device is an ALGO 8180 IP Audio Alerter
-
Check the firmware versionAccess the device's web interface or administrative console and navigate to the firmware/version information section. Alternatively, check via SNMP or the device's API if available. Compare the installed firmware version to the affected version.Affected if The installed firmware version is exactly 5.5
-
Verify web interface accessibilityConfirm the device's web-based management interface is reachable on the network (typically HTTP/HTTPS on ports 80 or 443, or a configured custom port). Check if the web service is enabled.Affected if The web interface is enabled and network-accessible
-
Confirm authentication statusDetermine whether default or configured credentials are active for the web interface. Check if authentication is required to access the management functions.Affected if The device is authenticated (has valid credentials configured) and the web interface accepts logins
-
Identify user input parameters in web interfaceReview the web interface forms, API endpoints, or configuration fields that accept user-supplied input. These are the potential injection points.Affected if User-supplied input fields exist in the web interface that could be passed to system calls
A user is affected if they have an ALGO 8180 IP Audio Alerter device running firmware version 5.5 with the web interface enabled and accessible, where an attacker could supply malicious input through authenticated web interface parameters to execute commands.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization on all user-supplied parameters in the web interface before using them in system calls. Apply vendor firmware updates when available. As a compensating control, restrict web interface access to trusted networks or IP ranges.
