Hpe Nonstop Xabroker
Monthly
A stack-based buffer overflow in HPE NonStop XABroker can corrupt memory and terminate the broker process, handing an attacker who already holds a valid low-privilege account on the NonStop host a local denial-of-service primitive against a core system service. Exploitation is constrained: the CVSS vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:R) confirms the attack is local, requires an authenticated low-privilege account, and needs a separate user action to deliver or process the crafted input, with our independent assessment narrowing the impact to availability only (S:U/C:N/I:N/A:H) rather than the confidentiality and integrity loss implied by the vendor-published score. There is no public exploit identified at time of analysis, no CISA KEV listing, and no EPSS data supplied, so this rates as a moderate, availability-focused issue that matters most in environments where untrusted or semi-trusted users already have NonStop logon rights.
