MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires: (1) valid AOS-CX operator-level credentials - unauthenticated access is not possible per PR:L in the CVSS vector; (2) a required user action (UI:R) that must occur before or during exploitation - the exact nature of this action is not disclosed in the advisory or description; (3) network-level reachability to the AOS-CX management API (AV:N). What limits exploitation: the mandatory user interaction requirement prevents fully automated or drive-by attacks; the attacker must already hold an operator account, ruling out fully external threat actors without prior foothold; and impact is read-only (C:H/I:N/A:N), meaning an attacker cannot modify device configuration or disrupt operations through this vulnerability alone. |
| Impact | The CVSS 5.7 score (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N) accurately reflects a medium-tier issue: network-reachable, low complexity, but gated by both authentication (operator credential required) and user interaction (some secondary action must be triggered). The UI:R requirement meaningfully depresses real-world risk - opportunistic mass exploitation is not feasible. Impact is confidentiality-only (C:H), with no integrity or availability consequence. No EPSS data, KEV listing, or public exploit was provided, and no public exploit has been identified at time of analysis. Within the hpesbnw05134 advisory bundle, this is the lowest-severity entry; defenders should triage it after the unauthenticated RCE (CVE-2026-73749, CVSS 9.8) and the adjacent format-string RCE (CVE-2026-73782, CVSS 8.8). The primary realistic threat scenario is a malicious insider or compromised operator account, not an external attacker. |
| Exploit ScenarioDerived | An internal network operator with valid low-privilege credentials authenticates to the AOS-CX management API and, after performing or inducing a specific required user action (the exact action is not disclosed in available data), issues a crafted API request to an endpoint that improperly bypasses role-based access checks. The operator retrieves sensitive configuration or credential data scoped to administrator-tier roles. No public exploit code has been identified at time of analysis, and the UI:R requirement limits opportunistic exploitation. |

Alert meAnalysisAIv1 – Sep 01, 2026
Privilege escalation in HPE AOS-CX's API endpoint allows an authenticated low-privilege operator to access sensitive system information that should be restricted to higher-privilege roles, provided a required user action is completed. The CVSS vector (PR:L/UI:R/C:H/I:N/A:N) confirms this manifests as an information disclosure escalation rather than full privilege takeover - a low-privilege operator reads confidential data normally gated behind elevated roles. This CVE is part of the same HPE advisory (hpesbnw05134) as CVE-2026-73749 (unauthenticated RCE, CVSS 9.8), CVE-2026-73766 (admin command injection, CVSS 7.2), CVE-2026-73778 (default-credential auth bypass, CVSS 8.1), and CVE-2026-73782 (adjacent format-string RCE, CVSS 8.8); no public exploit has been identified at time of analysis.
RemediationAI
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 provided in the available input data. As an interim compensating control, restrict API management-plane access to trusted management VLANs or out-of-band networks using ACLs, reducing the AV:N exposure to a more constrained access zone. Audit and minimize operator-role account provisioning, ensuring only accounts with operational need have credentials on the device. Given this CVE shares an advisory with higher-severity issues (including an unauthenticated RCE), patching the full hpesbnw05134 advisory bundle should be treated as a single maintenance event rather than triaged individually.

Technical ContextAI · show details
AOS-CX is HPE's modern network operating system for the Aruba CX switch portfolio, exposing a REST/gRPC API for management plane operations. The vulnerability resides in API endpoint access control, where role-based permission checks for operator-tier accounts are insufficiently enforced, permitting read access to resources scoped to higher-privilege roles (administrator or manager). The CPE cpe:2.3:a:hewlett_packard_enterprise_(hpe):aos-cx:*:*:*:*:*:*:*:* spans all versions across the software application facet. No CWE root-cause class was assigned by the reporter, but the behavioral pattern maps to CWE-285 (Improper Authorization) or CWE-269 (Improper Privilege Management) - an authorization boundary failure rather than a memory-safety or injection flaw.
