Concrete CMS Cross-site Scripting (XSS) in the Advanced File Search Filter

Low severity GitHub Reviewed Published Apr 3, 2024 to the GitHub Advisory Database • Updated Apr 3, 2024

Package

composer concrete5/concrete5 (Composer)

Affected versions

Description

Concrete CMS versions 9 below 9.2.8 and versions below 8.5.16 are vulnerable to Cross-site Scripting (XSS) in the Advanced File Search Filter. Prior to the fix, a rogue administrator could add malicious code in the file manager because of insufficient validation of administrator provided data. All administrators have access to the File Manager and hence could create a search filter with the malicious code attached. The Concrete CMS security team gave this vulnerability a CVSS v3.1 score of 3.1 with a vector of AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator .

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.
