CVE-2020-4599

Vulnerability

IBM Security Guardium Insights version 2.0.2 has a vulnerability in error handling that returns detailed technical error messages in the browser. This can expose sensitive information about the system configuration or internal state. The condition is triggered when an error occurs during normal application usage. [1]

Exploitation

A remote attacker can exploit this by sending requests that cause the application to produce an error, resulting in a detailed error message displayed in the browser. No authentication is required to trigger the error. The attacker does not need any special privileges or user interaction. [1]

Impact

Successful exploitation allows the attacker to obtain sensitive information that could be leveraged in further attacks against the system. The primary impact is information disclosure (confidentiality), with no direct effect on integrity or availability. [1]

Mitigation

IBM has released a fix for this vulnerability in Security Guardium Insights. Users should upgrade to a patched version as specified in the security bulletin [1]. If a fix is not yet applied, consider limiting access to the system or implementing error handling that suppresses detailed error messages.
