CVE-2026-73771
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk24th percentile - higher than 24% of all known CVEs
Summary
An authentication vulnerability in the AOS-CX management interface and API may allow improper authentication processing. An unauthenticated remote attacker could bypass authentication controls or exhaust system resources, leading to unauthorized access or DoS of the management interface.
Risk Assessment
Possible unauthorized access to device management or service disruption, threatening network security.
Recommendation
Install security patches and implement additional authentication mechanisms, e.g., MFA.
Other vulnerabilities in AOS-CX
See all- CVE-2026-73749Critical
Multiple vulnerabilities exist in a daemon of AOS-CX that may allow for improper processing of malformed input. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted packets to the affected service. Successful exploitation could result in remote code execution with elevated privileges.
- CVE-2026-73783Medium
Stack overflow vulnerabilities exist in an API endpoint of AOS-CX. Successful exploitation could allow an authenticated malicious actor to cause a denial-of-service condition on the affected system.
- CVE-2026-73782High
A format string vulnerability exists in the command line interface of AOS-CX that could lead to unauthenticated remote code execution. Successful exploitation allows arbitrary code execution as a privileged user on the underlying operating system.
- CVE-2026-73781High
A stored cross-site scripting (XSS) vulnerability exists in the web-based management interface of AOS-CX, allowing an authenticated remote attacker to attack an administrative user. Successful exploitation enables arbitrary script execution in the victim's browser in the context of the interface.
- CVE-2026-73780High
The web-based management interface of AOS-CX switches exposes some sessions to a lack of Cross-Site Request Forgery (CSRF) protection. This could allow a remote unauthenticated attacker to execute arbitrary input against the interface if the attacker convinces an authenticated user to interact with a specially crafted URL.
- CVE-2026-73779High
Vulnerabilities have been identified in the operating system of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. Successful exploitation could compromise system integrity and further expose sensitive information.
- CVE-2026-73778High
A vulnerability exists in the Credential Manager component that may allow for unauthorized administrative access. An unauthenticated remote attacker could exploit this vulnerability on a device in its factory-default or post-ZTP state before any administrator has configured credentials by providing a predictable factory-default password. Successful exploitation could result in full administrative control of the affected device during the initial setup process.
- CVE-2026-73777High
Vulnerabilities have been identified in the API endpoint of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls.
- CVE-2026-73776High
A signature verification bypass vulnerability exists in the command line interface of AOS-CX. Successful exploitation could allow an authenticated malicious actor with administrative privileges to execute arbitrary code on the underlying operating system, when certain pre-conditions outside of the attacker's control are met.
- CVE-2026-73775High
Vulnerabilities in the API endpoint of AOS-CX could allow a remote attacker authenticated with low privileges to access sensitive information. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-CX.
Original NVD description (English source)
An authentication vulnerability exists in the AOS-CX management interface and API that may allow improper authentication processing. An unauthenticated remote attacker could exploit this vulnerability under specific conditions to bypass authentication controls or exhaust system resources. Successful exploitation could result in unauthorized access or denial of service affecting the management interface.
