This vulnerability arises from inadequate bounds checking when processing cached data, potentially enabling remote code execution with system-level privileges.","exploitability":"Exploitation requires a network-based attack with minimal preconditions, as the CSC service is accessible over the network and no authentication is needed for the vulnerable code path.","blast_radius":"If exploited, this vulnerability could allow attackers to gain full system control across affected Windows systems that have Client-Side Caching enabled, potentially affecting enterprise networks with multiple vulnerable endpoints.","remediation":"Disable the Client-Side Caching service immediately by setting the 'CSC' service to disabled in registry or group policy, as no specific fixed version is published for this vulnerability.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["privilege-escalation","remote-exploitation","windows"],"model":"garnet-coder","analyzedAt":"2026-10-18T09:55:01.568Z"}}
