Attack-Flow Graph

Executive Summary

This vulnerability in IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 allows a remote attacker to cause a denial of service by triggering uncontrolled recursion.

Detection Guidance

This vulnerability involves uncontrolled recursion leading to denial of service. Detection requires monitoring for unusual recursion patterns or service crashes in IBM Security Verify Access or IBM Verify Identity Access. Check logs for excessive recursion errors or service interruptions. No specific commands are provided in the context.

Impact Analysis

The vulnerability could lead to system unavailability due to excessive resource consumption from the denial of service, potentially disrupting authentication and identity management services.

Compliance Impact

The vulnerability causes a denial of service due to uncontrolled recursion, which could disrupt system availability. This may impact compliance with standards like GDPR (availability principle) and HIPAA (accessibility requirements) by potentially leading to service unavailability.

Mitigation Strategies

Apply the latest security patches or updates provided by IBM for IBM Security Verify Access or IBM Verify Identity Access to address the uncontrolled recursion issue. Monitor IBM's security advisories for updates and restrict network access to affected systems until patched.
