The manipulation with an unknown input leads to a authentication spoofing vulnerability. The CWE definition for the vulnerability is CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. As an impact it is known to affect integrity, and availability. CVE summarizes:

The IBM Lenovo Access Support acpRunner ActiveX control, as distributed in acpcontroller.dll before 1.2.8.0 and possibly acpir.dll before 1.0.0.9 (Automated Solutions 1.0 before fix pack 1), does not properly validate digital signatures of downloaded software, which makes it easier for remote attackers to spoof a download.
