DescriptionCVE.org

A local privilege escalation vulnerability in HPE Networking Fabric Composer could allow an authenticated privileged user on the underlying host to elevate their user privileges to those of a higher role. A successful exploit allows the attacker to change the state of certain settings of the affected system.

AnalysisAI

Local privilege escalation in HPE Networking Fabric Composer enables an authenticated, highly privileged operator on the underlying host to elevate their role within the Fabric Composer management hierarchy, gaining access to higher-privileged administrative functions. The impact is bounded to integrity - specifically the ability to alter certain system configuration settings - with no confidentiality or availability consequence reported. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold an authenticated, high-privilege (operator-tier or equivalent) session on the underlying host where Fabric Composer is installed - AV:L and PR:H in the CVSS vector confirm both conditions. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The real-world risk is modest. … 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 Consult the HPE security bulletin at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05133en_us&docLocale=en_US for the specific patched release version; the provided intelligence does not include an exact fix version, so the patch version is not independently confirmed here. … Detailed patch versions, workarounds, and compensating controls in full report.
