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
Kiteworks is a private data network (PDN). Prior to version 9.2.0, avulnerability in Kiteworks command execution functionality allows authenticated users to redirect command output to arbitrary file locations. This could be exploited to overwrite critical system files and gain elevated access. Version 9.2.0 contains a patch.

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 · moderate confidence

Kiteworks prior to version 9.2.0 contains a command execution vulnerability where authenticated users can redirect command output to arbitrary file locations. This path traversal in command handling allows overwriting critical system files, leading to privilege escalation.

MitigationUpgrade to Kiteworks version 9.2.0 or later. Until then, restrict command execution permissions and monitor for unauthorized file modifications.

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. Confirm Kiteworks installation
    Identify if Accellion Kiteworks is deployed in your environment by reviewing installed applications, service listings, or documentation of enterprise software
    Affected if Kiteworks is installed and the version is below 9.2.0
  2. Determine installed Kiteworks version
    Access the Kiteworks admin interface or check system documentation to locate the currently installed version number
    Affected if The installed version is lower than 9.2.0 (for example, 9.1.x, 9.0.x, or earlier)
  3. Identify command execution functionality
    Locate the command execution feature within Kiteworks by reviewing admin panels, feature documentation, or available modules
    Affected if The command execution functionality exists and is accessible to authenticated users
  4. Check for path traversal indicators
    Review command execution logs, audit trails, or shell history for redirection operators (such as >, >>, 2>) being used with user-supplied paths pointing outside expected directories
    Affected if Logs show command redirection to unexpected file paths, especially system directories or configuration files
  5. Inspect critical system files for unauthorized modifications
    Compare current versions of system files, configuration files, and startup scripts against known-good baselines or integrity checking tools
    Affected if Critical system files have been modified or created without documented change approval

You are affected if Kiteworks version is below 9.2.0 and the command execution feature is accessible to authenticated users in your environment.

Upgrade available Upgrade to 9.2.0 or later
Fixed in 9.2.0
Interim mitigation

Upgrade to Kiteworks version 9.2.0 or later. Until then, restrict command execution permissions and monitor for unauthorized file modifications.

Recommended fix High confidence

Kiteworks version 9.2.0

  1. Upgrade Kiteworks to version 9.2.0 or later to remediate the command injection vulnerability
