ArubaOS (AOS): Exposure of Sensitive Information to an Unauthorized Actor

CVE-2026-79871 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in ArubaOS (AOS) from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 9.6 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected ArubaOS (AOS) versions: 10.8.0.0 through 10.8.1.1; 10.7.0.0 through 10.7.2.6; 10.4.0.0 through 10.4.1.13. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.31% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

A sensitive information disclosure vulnerability in the command line interface of AOS-10 could allow an unauthenticated remote attacker to access sensitive information. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-10.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
