DescriptionCVE.org

IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to a security bypass due to improper authentication controls. A local attacker could exploit this vulnerability to escalate privileges and gain unauthorized access to protected resources.

AnalysisAI

IBM WebSphere Application Server 9.0 and 8.5 contain a local privilege escalation flaw rooted in improper code injection controls (CWE-94) that subverts authentication enforcement, allowing a local attacker without prior privileges to gain unauthorized access to protected resources with high confidentiality and integrity impact. The attack is constrained to local access under complex conditions (CVSS AV:L/AC:H), which substantially limits its real-world reach compared to network-exploitable vulnerabilities. …

Vulnerability AssessmentAI

Exploitation	The attacker must have local access to the host running IBM WebSphere Application Server 8.5 or 9.0 - remote exploitation is not supported by the CVSS AV:L vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 vector AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N scores 6.7 (Medium), and the metric profile is notable: local-only access (AV:L) combined with high complexity (AC:H) significantly constrains exploitability compared to network-reachable flaws. … 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	Apply the vendor-released fix as detailed in IBM Security Advisory 7286610 at https://www.ibm.com/support/pages/node/7286610, which will specify the exact interim fix or fix pack level for WAS 8.5 and 9.0. … Detailed patch versions, workarounds, and compensating controls in full report.
