Attackers can create the missing directory, place a malicious file at the expected path, and cause the SYSTEM-level wvsc.exe process to load and execute it, resulting in full privilege escalation.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[]}
