CVE-2026-73740

A vulnerability has been identified in the SSH daemon of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to gain administrative access to vulnerable AFC hosts. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system leading to complete system compromise.

Vulnerabilities have been identified in the API of HPE Networking Fabric Composer that could potentially allow an unauthenticated remote attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative privileges leading to complete compromise of the HPE Networking Fabric Composer host.

An unauthenticated remote code execution vulnerability exists in the underlying operating system of HPE Networking Fabric Composer and could be exploited if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code as a privileged user on the underlying operating system, leading to complete compromise of the HPE Networking Fabric Composer host.

A vulnerability in the web-based management interface of HPE Networking Fabric Composer could allow an authenticated low privilege operator user to conduct a stored cross-site scripting (XSS) attack against an administrative user of the interface. A successful exploit could allow an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface.

An authentication bypass vulnerability exists in the underlying operating system of HPE Networking Fabric Composer. Successful exploitation could allow an unauthenticated adjacent attacker to execute arbitrary code as a privileged user on the underlying operating system, leading to complete compromise of the AFC host.

A vulnerability in the affected interface of HPE Networking Fabric Composer allows an attacker with administrative privileges to access sensitive information in cleartext format. Successful exploitation could allow retrieval of information that could be used to gain further access to network services.

A local privilege-escalation vulnerability has been discovered in HPE Networking Fabric Composer. Successful exploitation could allow an authenticated low-privilege operator user with local access to elevate their privileges and make limited modifications on the affected system.

A denial-of-service vulnerability exists in the API of HPE Networking Fabric Composer that could allow an authenticated low-privilege operator user to cause a denial of service. Successful exploitation could interrupt the normal operation of the affected service.

A vulnerability in the API endpoint of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to view some information handled by the affected system. Successful exploitation could allow insight into internal services and workflows, increasing the risk of unauthorized access when combined with other vulnerabilities.

A denial-of-service vulnerability exists in the web-based management interface of HPE Networking Fabric Composer that could allow an authenticated low-privilege operator user to cause a denial of service. Successful exploitation could disrupt the availability of the affected interface.
