CVE-2025-56266 Scanner

Avigilon ACM (Access Control Manager) is an enterprise-level security system designed to manage and control access to physical locations. It is typically used by corporations, government facilities, and large institutions requiring robust security measures. Avigilon ACM streamlines access privileges and integrates with existing security infrastructure, providing comprehensive management capabilities. The system allows administrators to set up access protocols, monitor access events, and manage credentials efficiently. Avigilon ACM is highly valued for its scalability and reliability, making it suitable for facilities of varying sizes. The software is maintained with frequent updates to address security vulnerabilities and improve functionality.

The Host Header Injection vulnerability allows attackers to manipulate HTTP requests by modifying the host header. This can lead to various exploits, such as executing arbitrary code or redirecting users to malicious websites. The vulnerability is particularly concerning in web applications that rely heavily on the host header for operations, potentially allowing attackers unauthorized access. Host Header Injection is often used as a stepping-stone for other attacks, damaging trust and exposing sensitive information. Such vulnerabilities highlight the importance of header validation in protecting web applications from exploitation. Failure to address this vulnerability could result in serious security breaches and data compromise.

The Host Header Injection vulnerability in Avigilon ACM can be exploited through maliciously crafted URLs that manipulate the HTTP host header. Attackers can use this vulnerability to send requests that execute arbitrary code on the server. The problematic endpoint in this scenario is typically where the application processes user-defined host headers without proper sanitation or validation. Additionally, this vulnerability may expose location-based logic errors if the application relies on the host header for redirections or access controls. The injection of arbitrary host values could lead to privilege escalation or unauthorized access within the application. As a result, it is vital to ensure that host headers are thoroughly validated against known and trusted domains.

Exploitation of the Host Header Injection vulnerability in Avigilon ACM could have severe repercussions. Attackers may gain remote execution capabilities, allowing them to compromise the entire system. Once inside, they could escalate privileges, install backdoors, or steal sensitive data, including usernames and access logs. Moreover, malicious actors could use the vulnerability to impersonate legitimate websites, defrauding users into divulging personal information. There is also a risk of the system being used as a launchpad for further network attacks, propagating the breach beyond the initial compromise. Immediate patching and robust host header validation are essential to mitigating these risks and maintaining system integrity.
