SimpleHelp Missing Authorization Vulnerability
SimpleHelp contains a missing authorization vulnerability that could allow low-privileged technicians to create API keys with excessive permissions. These API keys can be used to escalate privileges to the server admin role.
Quick answer
SimpleHelp should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.
Who is affected
Affected versions
- Review vendor advisory for affected versions.
Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2024-57726 affects SimpleHelp 5.5.7 and earlier and can let a low-privileged technician create API keys with excessive permissions. Because that can become server-admin access, remediation should include both patching and credential cleanup. Upgrade SimpleHelp 5.5 deployments to 5.5.8 or later, apply the vendor patches for supported 5.4/5.3 branches where needed, and rotate administrator, technician, and API credentials.
- Identify every SimpleHelp server and record the installed version from the server UI or the /allversions page.
- Upgrade SimpleHelp 5.5 installations to version 5.5.8 or later, or apply the vendor patch for supported 5.4.10 and 5.3.9 installations.
- Temporarily restrict technician and administrator logins to trusted IP ranges while patching.
- Remove API keys that were created before remediation unless they are explicitly required and reissued with least privilege.
- Reset the SimpleHelp administrator password and technician passwords that do not rely on a trusted external identity provider.
- Review technician roles, admin assignments, API key permissions, and recent administrative events for unexpected privilege changes.
- If compromise is suspected, preserve logs and rebuild the SimpleHelp host from a trusted backup or clean installer.

Verify the fix
- Confirm SimpleHelp reports 5.5.8 or later, or the correct patched legacy branch, after the update.
- Verify low-privileged technician accounts cannot create administrator-level API keys.
- Confirm login restrictions and MFA or external identity controls are in place for administrative access.
- Review the API key inventory and confirm old or excessive keys are removed.
- Run a Fixnx scan and internal access review to confirm no public admin exposure remains.
