Syncplify.me Server! 5.0.37 contains an unquoted service path vulnerability in the SMWebRestServicev5 service that allows local attackers to escalate privileges by exploiting the unquoted binary path. Attackers can insert a malicious executable into the service path and execute it with LocalSystem privileges when the service restarts or the system reboots.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
