CVE-2017-6480 Groovel Project CVE debrief

Who should care

Administrators, developers, and security teams running groovel/cmsgroovel versions earlier than 3.3.7-beta should treat this as relevant. It is especially important for any deployment where users can access the affected browser endpoint over the network.

Technical summary

NVD classifies the issue as CWE-79 (Improper Neutralization of Input During Web Page Generation) with a CVSS 3.0 vector of AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. The vulnerable surface is commons/browser.php, where the path parameter can be reflected in a way that enables script execution in the context of the victim’s session. NVD’s vulnerable version range indicates affected cmsgroovel builds up to and including 3.3.6, with 3.3.7-beta referenced as the fixed release.

Defensive priority

Medium

Recommended defensive actions

• Upgrade groovel/cmsgroovel to 3.3.7-beta or a later fixed release referenced by the vendor.
• Review commons/browser.php for unsafe reflection of the path parameter and apply strict output encoding.
• Add server-side input validation and context-aware output escaping for any user-controlled values rendered into HTML.
• Check application logs and web access logs for suspicious requests targeting commons/browser.php, especially crafted path values.
• If immediate patching is not possible, restrict exposure of the affected application to trusted users and networks until remediation is complete.

Evidence notes

The official NVD entry identifies this as CVE-2017-6480, maps it to CWE-79, and lists the vulnerable cpe range through version 3.3.6. The MITRE-cited vendor references point to a GitHub issue and the 3.3.7-beta release notes, supporting the remediation version and the affected component path. The CVSS vector indicates network reachability but requires user interaction, consistent with reflected XSS behavior.
