Name of the Vulnerable Software and Affected Versions Opto 22 SoftPAC Project versions 9.6 and prior

Description The issue arises because SoftPAC does not specify the path of multiple imported .dll files, allowing an attacker to replace them and execute code whenever the service starts.

Recommendations For versions 9.6 and prior, consider specifying the full path for all imported .dll files to prevent unauthorized replacements. As a temporary workaround, restrict access to the directory containing the .dll files to minimize the risk of exploitation.
