Concrete CMS Stored Cross-site Scripting vulnerability

Low severity GitHub Reviewed Published Mar 5, 2024 to the GitHub Advisory Database • Updated Sep 3, 2024

Package

composer concrete5/concrete5 (Composer)

Affected versions

< 9.2.7

Patched versions

9.2.7

Description

Concrete CMS version 9 before 9.2.7 is vulnerable to Stored XSS via the Name field of a Group type since there is insufficient validation of administrator provided data for that field. A rogue administrator could inject malicious code into the Name field which might be executed when users visit the affected page. The Concrete CMS security team gave this vulnerability a CVSS v3.1 score of 2.2 with a vector of AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N Concrete versions below 9 do not include group types so they are not affected by this vulnerability. Thanks Luca Fuda for reporting.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
