Concrete CMS vulnerable to stored XSS in file tags and description attributes

Low severity GitHub Reviewed Published Feb 9, 2024 to the GitHub Advisory Database • Updated Feb 15, 2024

Package

composer concrete5/concrete5 (Composer)

Affected versions

>= 9.0.0RC1, < 9.2.5

Patched versions

9.2.5

Description

Concrete CMS version 9 before 9.2.5 is vulnerable to stored XSS in file tags and description attributes since administrator entered file attributes are not sufficiently sanitized in the Edit Attributes page. A rogue administrator could put malicious code into the file tags or description attributes and, when another administrator opens the same file for editing, the malicious code could execute. The Concrete CMS Security team scored this 2.4 with CVSS v3 vector AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:N 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.
