Adjacent-network reachability to the admin console and high complexity from the bypass technique keep AV:A/AC:H, with no auth required and availability as the dominant impact.

DescriptionCVE.org

IBM WebSphere Application Server 9.0, and 8.5 could allow a remote attacker to bypass authentication on an admin console servlet.

AnalysisAI

An authentication bypass in IBM WebSphere Application Server 9.0 and 8.5 allows an attacker on an adjacent network segment to reach and invoke an administrative console servlet without valid credentials, because the servlet is missing the authorization check that should gate it (CWE-862). Successful exploitation gives low-level confidentiality and integrity exposure plus a high availability impact on the affected server. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the attacker to be positioned on an adjacent network with routing or L2 reachability to the WebSphere administrative console servlet endpoint - this is an AV:A flaw, so internet-only attackers without a foothold on the management segment cannot reach it. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 vector (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H, base 6.4) is the most informative signal here and is deliberately ambivalent: the attack vector is ADJACENT rather than NETWORK, meaning the attacker must already sit on a network segment with reachability to the console - this is not an internet-exposed, drive-by flaw. … 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	IBM has released a vendor patch for this issue, and the primary remediation is to apply the fix level documented in IBM's advisory at https://www.ibm.com/support/pages/node/7286610 - because the input does not name an exact fix pack or interim fix number, confirm the precise fix pack or interim fix identifier on that page before upgrading and do not assume a generic 'latest version' is sufficient. … Detailed patch versions, workarounds, and compensating controls in full report.
