Attack-Flow Graph

Executive Summary

This vulnerability affects IBM Security Verify Access versions 10.0 through 10.0.9.2 and IBM Verify Identity Access versions 11.0 through 11.0.3. An attacker with admin privileges and access to the local management interface could exploit an unbounded write to a fixed-size stack buffer to execute arbitrary code.

Detection Guidance

This vulnerability requires administrative privileges and access to the local management interface. Detection should focus on monitoring for unusual activity in the management interface or unexpected code execution. Check for unauthorized changes in configuration files or logs indicating stack buffer overflow attempts.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run arbitrary code on the affected system. This could lead to unauthorized access, data breaches, or further compromise of the system's integrity and confidentiality.

Compliance Impact

The vulnerability allows arbitrary code execution with administrative privileges, which could lead to unauthorized access or data breaches. This may impact compliance with GDPR (data protection) and HIPAA (healthcare data security) by potentially exposing sensitive information or violating confidentiality requirements.

Mitigation Strategies

Apply the latest security patches from IBM for IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 to fix the unbounded write vulnerability.
