CVE-2020-4174

Vulnerability

IBM Security Guardium Insights 2.0.1 employs cryptographic algorithms that are weaker than expected, allowing an attacker to decrypt highly sensitive information. This weakness resides in the encryption mechanisms used by the product, which do not meet modern security standards. The vulnerability is present in version 2.0.1 of IBM Security Guardium Insights, as reported in the IBM Security Bulletin [1].

Exploitation

An attacker can exploit this weakness without requiring any special network position or authentication. The attacker only needs to intercept or access encrypted data transmitted or stored by the system. By leveraging the weak cryptographic algorithms, the attacker can decrypt the protected information without needing to break the encryption through brute force or other advanced techniques. The exploitation does not require user interaction or race conditions; it is a straightforward decryption of data due to insufficient cryptographic strength.

Impact

Successful exploitation allows the attacker to obtain highly sensitive information that was intended to be protected by encryption. This disclosure could include confidential data such as user credentials, internal communications, or other private material. The impact is a breach of confidentiality, with no direct effect on integrity or availability. The attacker gains access to sensitive data at the same privilege level as the intended recipient, without escalating privileges or compromising system operations.

Mitigation

IBM has addressed this vulnerability in a security bulletin [1]. The fix involves upgrading to a version of IBM Security Guardium Insights that employs stronger cryptographic algorithms, meeting current security standards. As of the publication date, the specific fixed version is not detailed in the bulletin, but users are advised to apply the recommended updates from IBM to remediate the weakness. No workarounds are provided; the only mitigation is to install the patched release.
