CRITICAL 10.0

DescriptionCVE.org

IBM Common Licensing Agent 9.0, Agent 9.0.0.1, Agent 9.0.0.2, ART 9.0, ART 9.0.0.1, and ART 9.0.0.2 is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts.

AnalysisAI

Cross-site request forgery in IBM Common Licensing Agent and ART 9.0.x allows remote attackers to execute unauthorized actions on behalf of an authenticated user, with high integrity impact but no confidentiality or availability impact. Exploitation requires the victim to visit a malicious page while authenticated to the licensing web interface; no public exploit identified at time of analysis. Vendor assigned CVSS 10.0, but independent analysis assesses a more moderate risk due to the UI:R and S:U characteristics typical of CSRF.

Technical ContextAI

The vulnerability is a classic cross-site request forgery (CSRF, CWE-352) affecting the web interface of IBM Common Licensing Agent and ART versions 9.0, 9.0.0.1, and 9.0.0.2. The CPE cpe:2.3:a:ibm:common_licensing:*:*:*:*:*:*:*:* indicates the flaw resides in the common licensing component. CSRF occurs when the application fails to verify that a request originated from its own origin, allowing an attacker to craft a malicious link or page that, when visited by an authenticated user, triggers unintended actions within the licensing interface. The vendor's CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) rates this as a perfect 10.0, but this is anomalous for CSRF; the independent assessment (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) reflects the necessary user interaction and scope-unchanged characteristics, limiting the achievable impact to integrity violations bounded by the victim's privileges.

RemediationAI

Patch available per vendor advisory: apply the fix referenced in IBM's advisory at https://www.ibm.com/support/pages/node/7286490. No exact patch version is specified, but the advisory provides the necessary updates for Common Licensing Agent and ART 9.0 through 9.0.0.2. Until patching, reduce risk by ensuring the licensing web interface is only accessible from trusted management networks, avoiding exposure to untrusted networks. Administrators should log out after use and refrain from browsing other sites in the same browser session, or use a dedicated browser profile for administrative tasks. These measures lower the likelihood of a successful CSRF attack but do not fully eliminate the risk; applying the vendor patch is the definitive remediation.
