Attack-Flow Graph

Executive Summary

IBM i Access Client Solutions versions 1.1.2.0 through 1.1.9.13 on Windows are vulnerable to arbitrary code execution when installed for all users. This occurs because a configuration file is publicly writable, allowing attackers with local access to modify it and execute malicious code with elevated privileges.

Detection Guidance

Check for IBM i Access Client Solutions installations with version 1.1.2.0 through 1.1.9.13. Verify if the configuration file is publicly writeable by running: icacls "C:\ProgramData\IBM\iAccess\config\*.properties" on Windows. Look for files with write permissions granted to 'Everyone' or 'Users'.

Impact Analysis

If you use IBM i Access Client Solutions on Windows with all-user installation, an attacker with local access could exploit this to run arbitrary code on your system. This could lead to data theft, system compromise, or further network infiltration depending on your environment.

Compliance Impact

This vulnerability could violate compliance requirements that mandate secure configurations and access controls, such as GDPR's data protection principles or HIPAA's safeguards for protected health information. Unauthorized code execution risks exposing sensitive data, leading to potential regulatory penalties.

Mitigation Strategies

Update IBM i Access Client Solutions to the latest version. Remove write permissions from the configuration file by running: icacls "C:\ProgramData\IBM\iAccess\config\*.properties" /deny Everyone:(W) /deny Users:(W). Restrict installation to specific users only.
