CVE-2020-4258

Vulnerability

A memory corruption vulnerability exists in IBM i2 Intelligent Analysis Platform version 9.2.1 [1]. The flaw is triggered when the application parses a specially crafted file prepared by an attacker. This is a local attack vector, as it requires user interaction to open the malicious file [1].

Exploitation

An attacker must convince a victim to open a specially crafted file, for example via social engineering or by embedding the file in an email attachment. No authentication or special privileges are needed to trigger the vulnerability; only a standard user executing the vulnerable application [1].

Impact

Successful exploitation allows the attacker to execute arbitrary code with the privileges of the victim. This can result in a complete compromise of confidentiality, integrity, and availability (CIA) on the affected system, including potential installation of malware or data theft [1].

Mitigation

IBM has released a fix; details are available in the security bulletin reference [1]. Users should update their IBM i2 Intelligent Analysis Platform to version 9.2.1 with the applicable patch. No workaround is documented. Affected versions include 9.2.1 only. This CVE is not listed in the CISA Known Exploited Vulnerabilities catalog at the time of writing.
