DescriptionCVE.org

Vulnerabilities in the API of HPE Networking Fabric Composer could allow an authenticated remote attacker to conduct SQL injection attacks against the HPE Networking Fabric Composer instance. An attacker could exploit these vulnerabilities to obtain and modify sensitive information in the underlying database potentially leading to complete compromise of the HPE Networking Fabric Composer host.

AnalysisAI

SQL injection vulnerabilities in HPE Networking Fabric Composer's API allow authenticated remote attackers holding high-privilege accounts to read and modify the underlying database, with HPE warning this could escalate to complete compromise of the Fabric Composer host. The CVSS vector (PR:H, AV:N, AC:L) confirms the attack is network-reachable with no special complexity, but requires pre-existing administrative credentials - constraining exposure to insider threats or post-credential-compromise scenarios. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with high-privilege (administrator-level) credentials on the HPE Networking Fabric Composer instance, as confirmed by the CVSS PR:H metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 7.2 (High) is calibrated by PR:H, which meaningfully narrows the attack surface to actors already holding administrative credentials - this rules out opportunistic internet-scale exploitation. … 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 HPE Security Bulletin hpesbnw05133en_us at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05133en_us&docLocale=en_US for the vendor-released patch and exact fixed version - no specific patch version was extractable from the available input metadata. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit and document all current administrative accounts accessing Fabric Composer; review the past 30 days of API logs for anomalous database query patterns. …
