Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

AI-suggested

1. Immediately restrict network access to the ALGO 8180 IP Audio Alerter web interface using network segmentation, firewalls, or VPNs to limit exposure to trusted administrators only. 2. Enforce strong, unique authentication credentials and consider multi-factor authentication if supported to reduce the risk of credential compromise. 3. Monitor device logs and network traffic for unusual commands or access patterns indicative of exploitation attempts. 4. Disable or limit unnecessary services and interfaces on the device to reduce attack vectors. 5. Implement strict input validation and sanitization controls if device configuration allows customization. 6. Engage with ALGO for firmware updates or patches addressing this vulnerability; apply them promptly once available. 7. Conduct regular security audits and penetration tests focusing on device management interfaces. 8. Develop incident response plans that include scenarios involving compromised alerting devices to minimize operational disruption. 9. Educate administrators on the risks of command injection vulnerabilities and secure management practices. 10. Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures targeting command injection attempts on the device’s management ports.

Description

CVE-2026-0796 is a high-severity OS command injection vulnerability in the ALGO 8180 IP Audio Alerter's web UI. It allows authenticated remote attackers to execute arbitrary code on the device due to improper validation of user input before system calls. Exploitation requires valid credentials but no user interaction beyond authentication. The vulnerability impacts confidentiality, integrity, and availability of affected devices. No known exploits are currently reported in the wild. This flaw could be leveraged to disrupt audio alerting systems or pivot into internal networks. European organizations using ALGO 8180 devices should prioritize patching or mitigating this issue. Countries with critical infrastructure or large deployments of ALGO products are at higher risk. Immediate mitigation includes restricting access to the device UI, enforcing strong authentication, and monitoring for suspicious activity. The CVSS score is 7.

Impact

For European organizations, the impact of this vulnerability is substantial, particularly for those relying on ALGO 8180 IP Audio Alerter devices in critical communication and alerting infrastructures. Exploitation could lead to unauthorized control over alerting systems, resulting in denial of critical audio alerts or false alerts, which may disrupt emergency response, security operations, or operational continuity. Confidentiality is at risk as attackers could execute arbitrary commands to extract sensitive information or manipulate device logs. Integrity is compromised by the potential to alter device configurations or alert messages. Availability is threatened through possible device crashes or persistent compromise. Given the device’s role in physical security and safety systems, the operational impact could extend to public safety and regulatory compliance issues. The requirement for authentication limits the attack surface but does not eliminate risk, especially in environments with weak credential management or exposed management interfaces. European organizations with interconnected security systems or those in sectors such as transportation, utilities, or government are particularly vulnerable to cascading effects from such a compromise.

Summary

CVE-2026-0796 identifies a critical OS command injection vulnerability in the ALGO 8180 IP Audio Alerter, specifically in version 5.5. The vulnerability arises from improper neutralization of special elements in user-supplied input within the device's web-based user interface. This flaw allows an authenticated attacker to inject arbitrary OS commands by manipulating input fields that are passed directly to system calls without adequate sanitization or validation. The attack vector is network-based, requiring the attacker to authenticate to the device's web UI, but no further user interaction is necessary. Successful exploitation enables remote code execution with the privileges of the device's operating environment, potentially allowing attackers to alter device behavior, disrupt audio alerting functions, or use the device as a foothold for lateral movement within a network. The vulnerability was cataloged by the Zero Day Initiative (ZDI) as ZDI-CAN-28322 and assigned a CVSS v3.0 base score of 7.2, indicating high severity. Although no public exploits have been reported, the nature of the flaw and the critical role of the device in alerting systems make it a significant risk. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to reduce exposure.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #9OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
Architecture and Design
If at all possible, use library calls rather than external processes to recreate the desired functionality.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
Architecture and Design · Attack Surface Reduction
For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
