Summary
A vulnerability in the port ACL functionality of AOS-CX software on HPE Aruba Networking CX 9300 Switch Series. Affects AOS-CX 10.14.xxxx (all patches) and 10.15.1000 and below. An attacker can bypass ACL rules applied to routed ports on egress, leading to unauthorized traffic flow and security policy violations. Egress VLAN ACLs and Routed VLAN ACLs are not affected.
Risk Assessment
Risk of unauthorized network traffic and security policy violations on CX 9300 switches, potentially allowing an attacker to access unauthorized resources or services.
Recommendation
Apply available patches or upgrade AOS-CX software to a fixed version. Review ACL configurations on routed ports.
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)
A vulnerability has been identified in the port ACL functionality of AOS-CX software running on the HPE Aruba Networking CX 9300 Switch Series only and affects: - AOS-CX 10.14.xxxx : All patches - AOS-CX 10.15.xxxx : 10.15.1000 and below The vulnerability is specific to traffic originated by the CX 9300 switch platform and could allow an attacker to bypass ACL rules applied to routed ports on egress. As a result, port ACLs are not correctly enforced, which could lead to unauthorized traffic flow and violations of security policies. Egress VLAN ACLs and Routed VLAN ACLs are not affected by this vulnerability.
