CVE-2026-73781
HighCVSS 8.4Summary
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.
Risk Assessment
An attacker can hijack an administrator session, steal data, or perform unauthorized actions in the management interface, potentially compromising the entire network.
Recommendation
Apply vendor patches. Restrict access to the management interface and educate administrators about the risk of clicking suspicious links.
Other vulnerabilities in AOS-CX
See all- 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-2026-73780High
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.
- CVE-2026-73774High
A buffer overflow vulnerability exists in the underlying operating system of AOS-CX that could lead to unauthenticated disclosure of sensitive information by sending specially crafted packets to the affected system. Successful exploitation could result in limited disclosure or modification of information and disruption of the affected system.
- CVE-2026-73773High
An unauthenticated Denial-of-Service (DoS) vulnerability exists in the API endpoint of AOS-CX. Successful exploitation allows interruption of normal operation of the affected service.
Original NVD description (English source)
A vulnerability in the web-based management interface of AOS-CX could allow an authenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against an administrative user of the interface. A successful exploit allows an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface.
