Overview
CVE-2025-37159 describes a medium-severity vulnerability affecting the web management interface of the AOS-CX operating system user authentication service. This vulnerability could allow a remote attacker, after successful authentication, to hijack an active user session. Exploitation of this vulnerability could grant the attacker unauthorized access, potentially leading to the viewing or modification of sensitive configuration data.
Technical Details
The vulnerability resides within the session management of the AOS-CX web interface. It is suspected that the session identifier is not properly protected or regenerated after authentication, or that there is a lack of adequate session validation. This allows an attacker who has already authenticated to potentially predict or obtain another user’s session identifier and use it to impersonate that user.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-37159 a score of 5.8 (MEDIUM). This score reflects the following characteristics:
- Attack Vector (AV): Network (N) – The vulnerability is exploitable over a network.
- Attack Complexity (AC): Low (L) – Exploitation requires minimal effort.
- Privileges Required (PR): Low (L) – Attacker needs some level of authentication.
- User Interaction (UI): None (N) – No user interaction is required for exploitation.
- Scope (S): Unchanged (U) – The vulnerability does not affect resources beyond the security scope managed by the security authority.
- Confidentiality Impact (C): Low (L) – Limited impact on confidentiality.
- Integrity Impact (I): Low (L) – Limited impact on integrity.
- Availability Impact (A): None (N) – No impact on availability.
Possible Impact
Successful exploitation of CVE-2025-37159 could have several negative consequences:
- Unauthorized Access: An attacker can gain unauthorized access to the AOS-CX device’s web management interface.
- Configuration Modification: The attacker may be able to modify sensitive network configurations, potentially disrupting network operations or creating further vulnerabilities.
- Data Exposure: Sensitive configuration data, such as passwords and network keys, could be exposed to the attacker.
Mitigation or Patch Steps
To mitigate the risk associated with CVE-2025-37159, it is highly recommended to take the following steps:
- Apply the Patch: Upgrade your AOS-CX operating system to the latest version that addresses this vulnerability. Refer to the HPE Security Bulletin for specific patch details.
- Enforce Strong Passwords: Implement strong password policies for all user accounts.
- Multi-Factor Authentication (MFA): Enable MFA for all administrative accounts to add an extra layer of security.
- Network Segmentation: Implement network segmentation to limit the impact of a successful attack.
- Regular Security Audits: Conduct regular security audits to identify and address potential vulnerabilities.
