AzuraCast/AzuraCast vulnerable to cross-site scripting

Low severity GitHub Reviewed Published Apr 20, 2023 to the GitHub Advisory Database • Updated Nov 7, 2023

Package

composer azuracast/azuracast (Composer)

Affected versions

< 0.18.0

Patched versions

0.18.0

Description

AzuraCast/AzuraCast prior to version 0.18.0 is vulnerable to stored cross-site scripting. An issue was identified where a user who already had an AzuraCast account could update their display name to inject malicious JavaScript into the header menu of the site. In a majority of cases, this menu is only visible to the current logged-in user (pages like the Administer Users page are unaffected by this vulnerability), but if a higher-privileged administrator uses the Log In As feature to masquerade as a user, then the JavaScript injection could exfiltrate certain data. Anonymous members of the public cannot exploit this vulnerability in an AzuraCast installation, so it is primarily of concern for multi-tenant installations (i.e. resellers).

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.
