9.1 CRITICAL

Remote management-plane access (AV:N, AC:L) but requires an existing high-privilege authenticated session (PR:H); code execution bypassing a protection mechanism gives full C/I/A impact with a scope change (S:C).

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 authenticated attacker to execute arbitrary code due to a protection mechanism failure.

AnalysisAI

Arbitrary code execution is possible in IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3, including their container variants, when a remote authenticated attacker with high privileges exploits a protection mechanism failure (CWE-693). Rated CVSS 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), the flaw has low attack complexity and needs no user interaction, but the PR:H requirement means only a high-privileged authenticated actor can trigger it, so realistic risk concentrates on privileged insiders or compromised admin credentials. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to already be a remote AUTHENTICATED actor holding HIGH privileges (per PR:H) on IBM Security Verify Access (10.0 through 10.0.9.2) or IBM Verify Identity Access (11.0 through 11.0.3), including their container variants. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely high-priority flaw in enterprise identity software, but the risk is bounded by a meaningful authentication barrier. … 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 available per vendor advisory: apply the fix from the IBM Security Bulletin at https://www.ibm.com/support/pages/node/7291628, which confirms a vendor patch is available though the exact fixed build is not specified in the provided data. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all instances of IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3, including container variants, and identify which are internet-facing or host high-privilege administrative accounts; apply the vendor patch per IBM advisory where feasible, and if immediate patching is not possible, restrict high-privileged access and monitor admin sessions closely. …
