Severity by source
AV:A/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H
Adjacent vector, high complexity from external conditions, high privileges for authenticated admin, and required user interaction all match the described multi-condition exploitation path with OS-level scope change.

3DescriptionCVE.org
An authenticated arbitrary file write vulnerability exists in AOS-CX. Successful exploitation could allow an authenticated malicious actor, under specific conditions outside the attacker's control and following a required action by another user, to create or modify arbitrary files and execute arbitrary commands as a privileged user on the underlying operating system.
AnalysisAI
Authenticated arbitrary file write in HPE AOS-CX allows a high-privileged, adjacent attacker to create or modify arbitrary files and execute commands as a privileged user on the underlying operating system. Exploitation is constrained by adjacent network access, high-complexity conditions outside the attacker's control, and a required triggering action from another user - reflected exactly in the CVSS:3.1 AV:A/AC:H/PR:H/UI:R/S:C vector. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all four of the following conditions to coincide: (1) the attacker holds a high-privilege authenticated account on AOS-CX - a compromised administrator or malicious insider (PR:H); (2) the attacker has adjacent network access to the management plane, ruling out open-internet exploitation without prior network foothold (AV:A); (3) specific conditions outside the attacker's control must be present at the time of exploitation - their exact nature is not disclosed in the advisory (AC:H); and (4) a required action by a second authenticated user must occur to trigger the vulnerable code path (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.3 score captures a genuinely constrained but high-consequence vulnerability: adjacency (AV:A) prevents direct internet exploitation, high complexity (AC:H) imposes conditions outside the attacker's control, high privilege (PR:H) requires a pre-compromised admin account, and user interaction (UI:R) adds a timing dependency on a second authenticated user's action - meaning even a mid-sized municipal IT team in tczew managing a few AOS-CX switches would face exposure only through a convergence of insider access, management network reachability, and an opportunistic trigger event. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the HPE security bulletin at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05134en_us&docLocale=en_US for the specific patched AOS-CX firmware version; no exact fix version was included in the input data, so an upgrade target cannot be independently confirmed here. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all HPE AOS-CX deployments and document which high-privilege user accounts have access, verifying systems are only reachable from adjacent networks and not internet-facing. …
