Exploitation Conditions

Exploitation requires an authenticated session with high privileges (PR:H) on the management interface of an affected AOS-10 Gateway or AOS-8 Controller/Mobility Conductor; the attacker then abuses a path-traversal flaw in a low-level interface library to download files outside the intended directory. No user interaction is needed (UI:N). The principal limiting factor is the PR:H requirement - the actor must already possess administrative/operator-level access to the device, which sharply narrows the realistic attacker population to insiders or those who have already compromised an admin account. Impact is confined to reading files (confidentiality); no write/integrity or availability impact applies.

Impact

This is a moderate-severity, lower-priority issue rather than an urgent threat. The CVSS 3.1 base score is 4.9 (Medium) with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N - network-reachable and low-complexity, but critically gated behind PR:H, meaning the attacker must already hold high (administrative) privileges on the Aruba device. Impact is confidentiality-only (C:H, I:N, A:N): an authorized actor abusing a path-traversal flaw to read files they should not. The signals are consistent and point to low real-world urgency: EPSS is 0.45% (37th percentile), indicating low predicted exploitation likelihood; the CVE is NOT on the CISA KEV list; and no public exploit code was identified in the provided data. There is no conflict between the CVSS vector and the description - both agree on an authenticated actor. The main caveat is the high-privilege precondition: an attacker who already has administrative access to a network controller has substantial capability regardless of this specific flaw, which is likely why both CVSS and EPSS rate the real-world risk as modest. Prioritize via normal patch cycles rather than emergency response.

Exploit ScenarioDerived

An authenticated administrative user of an AOS-10 Gateway or AOS-8 Controller/Mobility Conductor sends a carefully constructed request to the vulnerable low-level interface library, using path-traversal sequences to download arbitrary files from the underlying filesystem (e.g., configuration or credential material) beyond their intended scope. Because exploitation requires existing high-privilege access (PR:H) and the complexity is low (AC:L), it is realistic only where a malicious or compromised admin account exists. No public proof-of-concept was identified at time of analysis.

AnalysisAIv1 – Oct 08, 2026

Path traversal in the low-level interface library of ArubaOS exposes AOS-10 Gateway and AOS-8 Controller/Mobility Conductor deployments to arbitrary file download from the local filesystem. Exploitation is network-reachable (AV:N) but gated behind a high-privileged authenticated session (PR:H), so a successful attacker must already hold administrative or operator-level access to the affected device; impact is limited to confidentiality (file reads), with no integrity or availability effect. There is no confirmed active exploitation (not in CISA KEV) and no public exploit code identified at time of analysis, and the EPSS score of 0.45% (37th percentile) indicates low predicted exploitation activity.

RemediationAI

Patch availability for CVE-2025-37145 is not independently confirmed from the data provided; there is no exact fixed version specified, so administrators should consult the HPE/Aruba advisory at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04957en_us&docLocale=en_US for the current fixed ArubaOS firmware for their AOS-10 Gateway or AOS-8 Controller/Mobility Conductor model and schedule an upgrade during a maintenance window, applying the vendor-released image as the primary fix. Until a fixed build is confirmed and deployed, treat the finding as a moderate, lower-priority hardening item and limit exposure by restricting the management interface to a dedicated out-of-band management VLAN or a small set of trusted administrator source addresses via ACLs or a firewall in front of the controller/conductor; the trade-off is reduced management flexibility and the need to update the allow-list as admin access points change. Enforce strong authentication and MFA on all administrative accounts, eliminate shared or service credentials, and audit for dormant or excessive admin logins, since PR:H means valid admin credentials are a precondition for exploitation. Because the impact is limited to file reads, monitor management-plane logs for anomalous or unexpected file-download requests and unusual read patterns targeting paths outside normal diagnostic directories; detection is constrained by the fact that the download itself may look like legitimate administrative activity, so correlate with source IP and session identity. Rotate administrative credentials if a compromised or over-privileged admin account is suspected, and note that none of these compensating controls remove the underlying path-traversal defect - only the vendor firmware update does.

Technical ContextAI · show details

The flaw is a classic path-traversal (CWE-22) in a low-level interface library shared by the ArubaOS AOS-10 Gateway and AOS-8 Controller/Mobility Conductor operating systems. Rather than failing to sanitize a user-supplied path before file I/O, the vulnerable library permits crafted path sequences to escape the intended download directory, letting a caller redirect a file-retrieval routine to arbitrary locations on the device filesystem. Because the code runs inside the management/control plane, the attacker reaches it over the network (AV:N with AC:L), but the CVSS vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N requires high privileges (PR:H) and needs no user interaction (UI:N). That PR:H prerequisite is the dominant risk limiter: the realistic attacker is an insider, a compromised admin account, or an actor who has already obtained elevated credentials. The CPE data maps the exposure to arubanetworks:arubaos across multiple version entries (all version ranges wildcarded), confirming the affected platform family is ArubaOS on both the gateway and controller/conductor product lines; the scope is unchanged (S:U) and there is no write or denial-of-service component, so this is a confidentiality-only defect in the management plane's file-handling library.
