DescriptionCVE.org

A vulnerability in the underlying operating system of HPE Networking Fabric Composer could allow an authenticated low privilege operator user with local access to obtain sensitive information. Successful exploitation could allow an attacker to retrieve sensitive data which could be used to gain further unauthorized access to the affected system and to other systems it interacts with.

AnalysisAI

Local information disclosure in HPE Networking Fabric Composer exposes sensitive operating-system-level data to authenticated low-privilege operator users with local system access. The CVSS Scope:Changed metric reflects that the leaked data crosses from the Fabric Composer application boundary into the underlying host OS, and HPE warns the recovered information could enable further unauthorized access to the affected system and interconnected infrastructure. …

Vulnerability AssessmentAI

Exploitation Three concurrent prerequisites are required: (1) a valid authenticated low-privilege operator account on HPE Fabric Composer - unauthenticated exploitation is excluded by CVSS PR:L; (2) local access to the host running Fabric Composer, specifically via local console or remote shell such as SSH - the CVSS AV:L vector explicitly excludes network-only (remote without shell) exploitation; (3) satisfaction of high attack complexity conditions (CVSS AC:H), indicating specific timing, race, or environmental prerequisites on the host OS that must be met for successful data extraction. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 5.6 accurately reflects a mid-severity, access-constrained finding. … 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 Patch available per vendor advisory - consult the HPE security bulletin at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05133en_us&docLocale=en_US for the specific fixed version and upgrade instructions; no exact patched version number is present in the available input data. … Detailed patch versions, workarounds, and compensating controls in full report.
