IBM DB2 Accessories Suite for Linux, UNIX, and Windows, DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow a local authenticated attacker to execute arbitrary code on the system, caused by DLL search order hijacking vulnerability in Microsoft Windows client. By placing a specially crafted file in a compromised folder, an attacker could exploit this vulnerability to execute arbitrary code on the system. IBM X-Force ID: 188149.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
