CVE-2020-4186: 
IBM Guardium Appliance vulnerability analysis and mitigation

IBM Security Guardium versions 10.5, 10.6, and 11.1 were found to contain an information disclosure vulnerability (CVE-2020-4186) that could expose sensitive information on the login page. The vulnerability was disclosed on July 29, 2020, and affects the login page functionality of the IBM Security Guardium platform (NVD, IBM Support).

The vulnerability has been assigned a CVSS v3.1 Base Score of 5.3 (Medium severity) with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. This indicates that the vulnerability is network-accessible, requires low attack complexity, needs no privileges or user interaction, has unchanged scope, and can impact confidentiality but not integrity or availability (AttackerKB).

The vulnerability could allow attackers to access sensitive information through the login page, which could potentially be used to facilitate further attacks against the system. The impact is primarily limited to confidentiality breaches, with no direct effect on system integrity or availability (IBM Support).

The vulnerability is characterized by its network accessibility and low attack complexity, requiring no special privileges or user interaction to exploit. This makes it relatively straightforward to attempt exploitation, though no reports of active exploitation in the wild have been documented (AttackerKB).

IBM has released security fixes for all affected versions (10.5, 10.6, 11.0, and 11.1) of Security Guardium. These patches are available through IBM's Fix Central platform. No alternative workarounds or mitigations have been identified (IBM Support).

The vulnerability was discovered and reported by the IBM X-Force Ethical Hacking Team, specifically by Jonathan Fitz-Gerald, John Zuccato, Rodney Ryan, Chris Shepherd, Nathan Roane, Kamil Sarbinowski, Vince Dragnea and Troy Fisher (IBM Support).
