CVE-2024-57726
About
SimpleHelp remote support software v5.5.7 and before has a vulnerability that allows low-privileges technicians to create API keys with excessive permissions. These API keys can be used to escalate privileges to the server admin role.
Rainforest analyst review
SimpleHelp fails to enforce proper authorization when technicians generate API keys, so a low-privileged technician account can create a key that carries far more permission than the role should allow. That over-privileged key is then used to escalate straight to the server administrator role, giving an attacker who holds even a minor technician login full control of the SimpleHelp server.
This was one of a chain of SimpleHelp flaws — alongside a path traversal (CVE-2024-57727) and a further privilege issue — exploited in early 2025, including by ransomware operators, to reach the downstream customer endpoints that a remote-support platform manages. Support and RMM servers are exactly the high-value pivots attackers seek, since one compromise fans out to many machines. Upgrade to a fixed SimpleHelp release, rotate any API keys and administrative credentials that could have been minted or exposed, and review connected endpoints for actions taken through the server.
