CVE-2020-4265

Vulnerability

A memory corruption vulnerability exists in IBM i2 Intelligent Analysis Platform version 9.2.1. The flaw occurs when the application parses a specially crafted file, leading to memory corruption that can be leveraged for code execution. The affected product is IBM i2 Analyst's Notebook and IBM i2 Analyst's Notebook Premium (both part of the i2 Intelligent Analysis Platform). No authentication is required for exploitation, but user interaction is needed as the victim must open the malicious file.

Exploitation

An attacker must craft a malicious file that triggers the memory corruption upon parsing. Exploitation is local; the attacker needs to persuade a victim (e.g., via social engineering) to open the file within the affected IBM i2 application. No special network position or previous authentication is required. Once the victim opens the file, the corrupted memory state can be exploited to hijack execution flow.

Impact

Successful exploitation allows the attacker to execute arbitrary code on the victim's system with the privileges of the user running the application. This typically results in full compromise of confidentiality, integrity, and availability (CIA), as the attacker can read, modify, or delete data, install malware, or perform further attacks. The CVSS v3.0 base score is 7.8 (High).

Mitigation

IBM has released a fix. Customers should apply the security update provided in IBM i2 Analyst's Notebook fix pack or upgrade to a patched version as directed in the advisory [1]. No workarounds are documented; the only mitigation is to install the vendor-supplied patch. Restricting file opening from untrusted sources can reduce risk but is not a complete mitigation.
