CVE-2018-5405 — Quest Kace Systems Management Appliance Firmware security vulnerability

Medium CVSS 5.4

The Quest Kace K1000 Appliance, versions prior to 9.0.270, allows an authenticated least privileged user with 'User Console Only' rights to potentially inject arbitrary JavaScript code on the tickets page. Script execution could allow a malicious user of the system to steal session cookies of other users including Administrator and take over their session. This can further be exploited to launch other attacks. The software also does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other user. An authenticated user with 'user console only' rights may inject arbitrary JavaScript, which could result in an attacker taking over a session of others, including an Administrator.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
