Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SimpleHelp remote support software v5.5.7 and before is vulnerable to multiple path traversal vulnerabilities that enable unauthenticated remote attackers to download arbitrary files from the SimpleHelp host via crafted HTTP requests. These files include server configuration files containing various secrets and hashed user passwords.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

SimpleHelp remote support software versions 5.5.7 and before contains multiple path traversal vulnerabilities in its file download functionality. Unauthenticated attackers can craft HTTP requests with directory traversal sequences (such as ../../) to escape the intended directory and download arbitrary files from the server, including sensitive configuration files containing secrets and hashed user passwords.

MitigationUpgrade SimpleHelp to a version newer than v5.5.7 which contains the security patches for these path traversal vulnerabilities. Additionally, restrict network access to the SimpleHelp management interface to trusted IPs as a defense-in-depth measure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SimpleHelp version
    Access the SimpleHelp web interface and look for the version information, typically displayed in the login page footer, About section, or in the server's installed files (check startup logs or configuration files for version metadata).
    Affected if The installed version is 5.5.7 or earlier (any version below 5.5.8).
  2. Confirm SimpleHelp web service is running
    Verify the SimpleHelp server process is active and the web interface is reachable on its configured port (default 8080 or 8443). Use a browser or curl to confirm the login page responds.
    Affected if The SimpleHelp web service is running and accessible over the network.
  3. Check network exposure
    Review firewall rules, network ACLs, or reverse proxy configurations to determine whether the SimpleHelp web interface is exposed to untrusted networks or the public internet.
    Affected if The SimpleHelp web interface is reachable from untrusted networks or the internet without access controls.
  4. Verify file-serving configuration
    Inspect SimpleHelp configuration files (typically in the installation directory under config or settings) for file-serving module settings or any directory access policies.
    Affected if File-serving features are enabled and accessible to unauthenticated requests.

A SimpleHelp server is affected if it runs version 5.5.7 or earlier, has its web interface accessible over the network, and has file-serving features enabled, allowing an attacker to use ../ sequences to read sensitive files outside the web root.

dbcve · scoped
Upgrade available Upgrade to 5.5.8 or later
Fixed in 5.5.8
Interim mitigation

Upgrade SimpleHelp to a version newer than v5.5.7 which contains the security patches for these path traversal vulnerabilities. Additionally, restrict network access to the SimpleHelp management interface to trusted IPs as a defense-in-depth measure.

Recommended fix High confidence

5.5.8

  1. Back up your current SimpleHelp installation and configuration files before proceeding with the upgrade.
  2. Download SimpleHelp version 5.5.8 from the official source at simple-help.com.
  3. Stop the SimpleHelp service or server.
  4. Install or upgrade to SimpleHelp version 5.5.8 using the standard installation process.
  5. Restart the SimpleHelp service.
  6. Verify that the installation was successful by checking the version number in the SimpleHelp admin interface.
  7. Test that path traversal vulnerabilities are mitigated by confirming normal file access functionality works correctly.
