CVE-2020-4262

Vulnerability

CVE-2020-4262 is a memory corruption vulnerability found in IBM i2 Intelligent Analysis Platform version 9.2.1. The issue arises when the application processes a specially-crafted file, such as a document or data file, leading to memory corruption. This vulnerability requires the victim to open the malicious file locally, meaning the attacker must first deliver the file and convince the user to open it [1].

Exploitation

Exploitation requires local access to the system, but no authentication is needed. The attacker crafts a malicious file that triggers memory corruption when opened by the victim in the i2 platform. The attacker must persuade the user to open the file (user interaction is required). Once opened, the corruption allows arbitrary code execution within the application's process context [1].

Impact

Successful exploitation allows the attacker to execute arbitrary code on the victim's system with the same privileges as the application user. This can lead to full compromise of the confidentiality, integrity, and availability of the system, as the attacker can read, modify, or delete data, install programs, or create new accounts [1].

Mitigation

IBM has released a fix as part of the IBM i2 Analyst's Notebook and IBM i2 Analyst's Notebook Premium security update. Affected users should upgrade to i2 Intelligent Analysis Platform version 9.2.1 or later as specified in the security bulletin. No workaround is available, and the vulnerability is not known to be listed in the CISA KEV. For details, refer to the IBM support page [1].
