Hewlett Packard Enterprise (HPE) has released patches for 34 CVEs in the Aruba Networking ArubaOS-CX (AOS-CX) platform, including critical-severity remote code execution (RCE) flaws. Per HPT’s advisory, more than 150 flaws were resolved in AOS-CX versions 10.18.1002, 10.17.1030, 10.16.1060, 10.13.1190, and 10.10.1181. Many of these bugs are tracked together under single CVEs. Nearly two dozen issues, tracked collectively as CVE-2026-73749 (CVSS score of 9.8), were addressed with the updates. The critical security defects are rooted in the improper processing of malformed input sent to an unnamed service within HPE’s database-centric operating system for enterprise switches. According to the company, an unauthenticated attacker could exploit the security defects by sending crafted packets to the vulnerable service, achieving RCE with elevated privileges. The fresh updates also resolve 22 high-severity CVEs that could lead to denial-of-service (DoS), RCE, arbitrary command execution, arbitrary script code execution in a victim’s browser, authentication bypass, privilege escalation, and information disclosure.Advertisement.

HPE says the majority of these vulnerabilities were discovered internally by its security team, noting that it is not aware of any of them being exploited in the wild. “To minimize the likelihood of an attacker exploiting these vulnerabilities, HPE Networking recommends that the CLI and web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above along with accounting controls for tracking and logging user activities and resource usage,” the company notes.
