**Name of the Vulnerable Software and Affected Versions**
Foxit PDF Reader (affected versions not specified)
Foxit PDF Editor (affected versions not specified)
**Description**
A privilege escalation issue exists in the update service `FoxitPDFReaderUpdater.exe` due to an uncontrolled search path. This allows low-privilege users to place executable files in a location where they are directly executed by high-privilege processes, enabling the attacker to execute arbitrary code and elevate their privileges to NT AUTHORITYSYSTEM.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
