CWE-427Published: October 22, 2021· Updated: Jun 17, 2026
7.1
CVSS v3.1
Official Description
Many of the services used by the affected product do not specify full paths for the DLLs they are loading. An attacker can exploit the uncontrolled search path by implanting their own DLL near the affected product’s binaries, thus hijacking the loaded DLL.
Technical Analysis
CVE-2021-38469 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.1.
