SimpleHelp Path Traversal Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 8 May 2026). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
SimpleHelp remote support software v5.5.7 and before allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file (i.e. zip slip). This can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user.
