CVE-2018-5404
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 · uneditedThe Quest Kace K1000 Appliance, versions prior to 9.0.270, allows an authenticated, remote attacker with least privileges ('User Console Only' role) to potentially exploit multiple Blind SQL Injection vulnerabilities to retrieve sensitive information from the database or copy the entire database. An authenticated remote attacker could leverage Blind SQL injections to obtain sensitive data.
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 confidenceMultiple Blind SQL Injection vulnerabilities in Quest Kace K1000 Appliance versions prior to 9.0.270 allow authenticated users with minimal 'User Console Only' role privileges to inject malicious SQL queries through vulnerable input fields, potentially enabling complete database exfiltration.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine the installed Kace K1000 firmware versionAccess the K1000 administrative interface and navigate to the System Overview or Settings > Appliance Settings > System Information to view the current firmware version. Alternatively, log in via SSH and run: ps -ef | grep Kbox or check /etc/version if accessible.Affected if The installed version is lower than 9.0.270 (e.g., 9.0.269, 9.0.260, 8.x, etc.)
-
Verify if the User Console is enabledLog into the K1000 admin interface and navigate to Settings > Security Settings > User Console settings, or check if the /userconsole endpoint is accessible and functional.Affected if The User Console is enabled and accessible to users with minimal privileges
-
Identify accounts with User Console Only roleIn the K1000 admin interface, go to Settings > User Authentication > Users or Roles to review user accounts and their assigned roles. Look for accounts assigned the 'User Console Only' role or equivalent minimal privilege role.Affected if Any user account exists with User Console Only or minimal role privileges, as these users can exploit the SQL injection
-
Review application logs for suspicious SQL-like patterns in User Console requestsAccess the K1000 logs via the admin interface (Reports > Logs) or SSH to /var/log/, and search for entries containing SQL keywords (SELECT, UNION, INSERT, --, etc.) in parameters passed through User Console endpoints.Affected if Logs contain SQL syntax or unusual characters in request parameters from User Console users, indicating potential exploitation attempts
A system is affected if it runs Quest Kace K1000 Appliance firmware version lower than 9.0.270, has the User Console enabled, and allows users with minimal privileges to access input fields that could be exploited for SQL injection.
