HPE released security updates for Aruba Networking AOS-CX to fix multiple vulnerabilities, including CVE-2026-23813, a critical flaw in the web management interface that can let a remote, unauthenticated attacker bypass authentication. In some cases, successful exploitation can also reset an administrator password and lead to full system compromise. The issue carries a CVSS 3.1 score of 9.8 and affects several release trains, including 10.17.0001 and earlier, 10.16.1020 and earlier, 10.13.1160 and earlier, and 10.10.1170 and earlier.
HPE advised customers to upgrade to fixed AOS-CX versions as soon as possible and published mitigation guidance for environments that cannot patch immediately. Recommended steps include restricting access to the management interface, disabling unnecessary HTTP(S) exposure on SVIs and routed ports, applying Control Plane ACLs for REST and HTTP management traffic, and enabling logging and continuous monitoring to detect exploitation attempts against Aruba CX switches.

HPE Aruba Networking has patched **CVE-2026-73749**, a critical buffer-overflow flaw in ArubaOS-CX that lets an unauthenticated remote attacker send crafted packets to a vulnerable daemon and execute code with elevated privileges on affected CX-series switches. Fixed releases include AOS-CX `10.18.1002`, `10.17.1030`, `10.16.1060`, `10.13.1190`, and `10.10.1181`; the `10.10.x` branch is end of support and receives limited remediation. The associated security bulletin also addresses 23 additional flaws, including command execution, arbitrary file write, authentication-bypass, privilege-escalation, denial-of-service, stored-XSS, CSRF, and predictable-default-password issues. HPE reports no known exploitation or public proof-of-concept for the disclosed vulnerabilities, but administrators should promptly upgrade to supported fixed releases; where patching is delayed, restrict management web-interface access to approved IP addresses.

Hewlett Packard Enterprise (HPE) released security updates for multiple products, including **HPE Aruba Networking AOS-CX** and **HPE Telco Intelligent Assurance**, and the Canadian Centre for Cyber Security amplified the guidance to review HPE advisories and apply the required patches. The Aruba AOS-CX updates address multiple issues in the switch OS, with reporting highlighting a **critical authentication bypass** in the web management interface that can allow an **unauthenticated remote attacker** to bypass authentication controls and, in some cases, **reset the admin password** (tracked as `CVE-2026-23813`). HPE stated it was not aware of public exploit code or active exploitation at the time of advisory publication. For **HPE Telco Intelligent Assurance**, HPE disclosed an **arbitrary code execution** risk tied to its deployment of **Apache Avro** when generating specific records from **untrusted Avro schemas** (`CVE-2025-33042`, CVSS 3.1 base score **7.3**). HPE indicated the affected Avro Java SDK versions include all versions through **1.11.4** and **1.12.0**, with fixes available in **1.11.5** or **1.12.1**; HPE Telco Intelligent Assurance remediation is provided via upgrading to **FAS 4.2.14** / **PDO 4.2.14**. Where immediate patching is not possible for Aruba AOS-CX, mitigations include restricting management-plane access (e.g., dedicated management VLAN/segment), enforcing L3 policies and control-plane ACLs, disabling unnecessary HTTP(S) exposure on SVIs/routed ports, and increasing logging/monitoring of management interface activity.

Hewlett Packard Enterprise released security updates for multiple vulnerabilities in **HPE Aruba Networking** access points running **Instant AOS-8** and **AOS-10**, including two critical flaws that can lead to remote code execution. The most severe issues, tracked as `CVE-2024-42509` and `CVE-2024-47460`, affect the CLI service and can be exploited by an unauthenticated attacker by sending specially crafted packets to **UDP port 8211**, where the **PAPI** management protocol listens, enabling command injection and code execution on vulnerable devices. HPE also addressed four additional high-severity vulnerabilities — `CVE-2024-47461`, `CVE-2024-47462`, `CVE-2024-47463`, and `CVE-2024-47464` — that could allow a remote authenticated attacker to execute code or access sensitive information. HPE advised organizations to upgrade to fixed **AOS-10** and **Instant AOS-8** releases immediately, restrict exposure of management interfaces if patching cannot be completed at once, and replace Aruba products that have reached end of support.
