CVE-2020-4166

Vulnerability

IBM Security Guardium Insights version 2.0.1 returns detailed technical error messages in the browser when an error occurs. This behavior exposes sensitive information that could be leveraged by an attacker. The vulnerability is present in the default configuration and does not require any special settings to be exploitable [1].

Exploitation

A remote attacker with no prior authentication can trigger an error condition by sending a crafted request to the Guardium Insights web interface. The server responds with a verbose error message containing internal details such as stack traces, file paths, or configuration data. No user interaction is required [1].

Impact

Successful exploitation results in the disclosure of sensitive information, which may include system paths, database credentials, or other internal state data. This information can be used to plan and execute further attacks against the system, potentially leading to broader compromise [1].

Mitigation

IBM has addressed this vulnerability in a security update. Users should upgrade to the latest version of IBM Security Guardium Insights as specified in the IBM security bulletin [1]. No workarounds are documented; applying the patch is the recommended course of action.
