Impact

The CVSS 3.1 score of 7.3 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L indicates a HIGH-severity vulnerability with multiple concerning characteristics: (1) Network-accessible attack vector requiring no special conditions, (2) Low attack complexity with no prerequisites, (3) No privilege or user interaction required, enabling full automation. The authentication bypass classification (CWE-287) is inherently high-risk as it directly undermines the security boundary. While confidentiality, integrity, and availability impacts are rated as Low individually, the combination of trivial exploitability with direct authentication bypass suggests attackers could enumerate or modify license data, potentially leading to license fraud or service disruption. This is a HIGH real-world priority requiring immediate patching, particularly for organizations with internet-facing APLS deployments. The absence of reported mitigating factors (no mention of narrow applicability or rare configurations) elevates the baseline risk.

Exploit ScenarioDerived

An unauthenticated attacker on the network identifies an HPE AutoPass License Server instance (versions <9.17) accessible over the internet or internal network. The attacker crafts HTTP/HTTPS requests to the APLS API or web interface, exploiting the authentication bypass flaw to gain unauthorized access without providing valid credentials. Once authenticated, the attacker could: (1) retrieve sensitive license data and customer information, (2) modify license allocations to enable unlicensed software usage, (3) revoke or transfer licenses maliciously, or (4) trigger license server denial-of-service conditions. Due to the low attack complexity and lack of user interaction required, this exploitation could be fully automated and incorporated into opportunistic scanning tools, making it likely to be discovered and leveraged quickly by threat actors targeting software supply chains or seeking to circumvent licensing controls. No special tools or deep technical knowledge are required—a simple curl command or HTTP client could exploit this vulnerability.

AnalysisAI

CVE-2024-51767 is an authentication bypass vulnerability in HPE AutoPass License Server (APLS) versions prior to 9.17 that allows unauthenticated remote attackers to gain unauthorized access to the application with limited impact on confidentiality, integrity, and availability. The vulnerability has a CVSS score of 7.3 (High) with a network-accessible attack vector requiring no privileges or user interaction, making it trivially exploitable. While specific KEV status and EPSS data are not provided in the available intelligence, the authentication bypass nature combined with the low attack complexity indicates this vulnerability likely poses a moderate-to-high real-world risk to unpatched HPE APLS installations.

Technical ContextAI · show details

The vulnerability stems from improper implementation of authentication mechanisms in HPE AutoPass License Server, classified under CWE-287 (Improper Authentication). HPE AutoPass License Server is a license management platform that authenticates and provisions software licenses. The affected versions prior to 9.17 likely contain flaws in session management, credential validation, or API authentication logic that allows attackers to bypass authentication controls. This could manifest as missing or improperly validated authentication tokens, weak cryptographic implementations, or logical flaws in the authentication flow. The network-accessible nature (AV:N) suggests the vulnerable endpoint is exposed on the network without requiring physical or local access, potentially through HTTP/HTTPS-based APIs or web interfaces used for license management operations.

DescriptionCVE.org

An authentication bypass vulnerability exists in HPE AutoPass License Server (APLS) prior to 9.17.

Executive ViewAI

Why It Matters

HPE AutoPass License Server versions prior to 9.17 contain an authentication bypass vulnerability that allows unauthenticated remote attackers to access the application over the network with no special privileges required. Organizations using APLS for license management face potential unauthorized access to licensing data and systems, creating compliance and operational risks if the vulnerability remains unpatched.

Business Impact: High
Compensating Controls

Apply vendor patch to version 9.17 or later. Pending patching: restrict network access to APLS servers using firewall rules to trusted internal networks only; implement network segmentation to limit exposure; enable detailed authentication and access logging to detect bypass attempts.
