CVE-2025-25040: Failure to Properly Enforce Port ACLs on CPU generated packets in CX 9300 Switches

Noroxi assessment

Priority: Monitor (action score 13/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
