Untrusted search path vulnerability in Multiple Yayoi 17 Series products (Yayoi Kaikei 17 Series Ver.23.1.1 and earlier, Yayoi Aoiro Shinkoku 17 Ver.23.1.1 and earlier, Yayoi Kyuuyo 17 Ver.20.1.4 and earlier, Yayoi Kyuuyo Keisan 17 Ver.20.1.4 and earlier, Yayoi Hanbai 17 Series Ver. 20.0.2 and earlier, and Yayoi Kokyaku Kanri 17 Ver.11.0.2 and earlier) allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory. This flaw exists within the handling of msjet49.dll loaded by the vulnerable products.

Weakness

The application searches for critical resources using an externally-supplied search path that can point to resources that are not under the application’s direct control.

Affected Software

Name Vendor Start Version End Version
Aoiro_shinkoku Yayoi-kk * 23.1.1
Hanbai Yayoi-kk * 20.0.2
Kaikei Yayoi-kk * 23.1.1
Kokyaku_kanri Yayoi-kk * 11.0.2
Kyuuyo Yayoi-kk * 20.1.4
Kyuuyo_keisan Yayoi-kk * 20.1.4

Extended Description

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the application 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 application would then execute. The problem extends to any type of critical resource that the application trusts. Some of the most common variants of untrusted search path are:
