DescriptionNVD

IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 could allow a remote attacker to bypass security restrictions due to improper authentication.

AnalysisAI

Authentication bypass in IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 lets remote, unauthenticated attackers circumvent security restrictions and gain access they should not have, with the assessed CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) indicating high confidentiality and integrity impact without any prior credentials or user interaction. The same flaw extends to the container editions of both products (Security Verify Access Container and Verify Identity Access Container), which are commonly deployed as internet-facing policy-enforcement points, so exposure of the affected component to untrusted networks is the primary precondition. …

Vulnerability AssessmentAI

Exploitation The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no authentication or user interaction is required, implying remote unauthenticated exploitation against affected IBM Security Verify Access (10.0-10.0.9.2) and Verify Identity Access (11.0-11.0.3) deployments, including their container editions. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely high-priority flaw that aligns strongly across the available signals. … 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 Patch status: Patch available per vendor advisory - IBM has published a fix and affected-product guidance at https://www.ibm.com/support/pages/node/7291628; because the exact fixed build numbers are not supplied in the available data, confirm the precise remediation level in that bulletin and upgrade IBM Security Verify Access beyond 10.0.9.2 and IBM Verify Identity Access beyond 11.0.3 (plus any affected container images) to the vendor-designated fixed release. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory every instance of IBM Security Verify Access (10.0 through 10.0.9.2) and IBM Verify Identity Access (11.0 through 11.0.3), including Security Verify Access Container and Verify Identity Access Container deployments, and determine which are reachable from untrusted networks; where internet exposure cannot be justified, restrict or remove that exposure through network controls as a stopgap and confirm with IBM Support which fix level applies to each release train. …
