CVE-2020-4263

Vulnerability

A memory corruption vulnerability exists in IBM i2 Intelligent Analysis Platform version 9.2.1. By opening a specially crafted file, a local attacker can trigger the bug and execute arbitrary code. The official description [1] notes the vulnerability is reachable via user interaction, requiring the victim to open the malicious file.

Exploitation

The attacker must convince a victim to open a specially crafted file, leveraging local user interaction. No additional authentication or special privileges are needed beyond the victim's own user context. The attack vector is local, meaning the attacker must have some form of access to deliver the file (e.g., via email, download, or removable media).

Impact

Successful exploitation allows the attacker to execute arbitrary code on the victim's system with the privileges of the victim. This can lead to full compromise of confidentiality, integrity, and availability (CIA) of the affected system.

Mitigation

IBM has released a security bulletin with fix information. According to reference [1], affected users should apply the patch provided by IBM for i2 Intelligent Analysis Platform 9.2.1. No workaround is disclosed in the available references; upgrading to the fixed version is the recommended mitigation.
