Security readout for executives and security teams
Plain-English summary
Quick.CMS 6.7 has an admin-side cross-site scripting flaw in the sliders form. An authenticated attacker can use a forged form submission to place script content that runs in an administrator’s browser. This is not a server takeover by itself, but it can expose admin session data or alter site content through the victim’s browser.
Executive priority
Treat this as a moderate web-application risk. It deserves prompt remediation if Quick.CMS 6.7 is internet-facing or business-critical, but it is below unauthenticated remote code execution urgency.
Technical view
The CVE describes CWE-79 XSS in Quick.CMS 6.7 through the sliders form sDescription parameter, reachable at the admin sliders form workflow. CVSS 3.1 is 5.4: network-reachable, low complexity, low privileges, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is limited to Opensolution Quick.CMS version 6.7 deployments, especially systems with reachable admin interfaces and authenticated users who manage sliders. The sources do not identify other affected versions or products.
Exploitation context
The source bundle includes an ExploitDB reference, so public exploit information exists. The CVE is not listed as KEV in the provided data, and no cited source states active exploitation in the wild.
Researcher notes
Evidence supports Quick.CMS 6.7 only, with XSS via sDescription in the sliders form and CSRF-assisted delivery. Patch status is not stated in the provided sources. Avoid expanding scope beyond the named version without independent vendor confirmation.
Mitigation direction
- Identify and prioritize any Quick.CMS 6.7 instances.
- Check Opensolution or advisory sources for a fixed release or supported replacement.
- Restrict administrative access to trusted networks and users.
- Review slider descriptions and remove unauthorized script-like content.
- Add or verify CSRF defenses and output encoding where maintainers support code changes.
Validation and detection
- Inventory Quick.CMS deployments and confirm exact versions.
- Check whether admin slider management is reachable from untrusted networks.
- Review slider description fields for unexpected HTML or script content.
- Review admin activity logs for unusual slider form submissions.
- Confirm whether compensating controls block forged admin form submissions.
