CVSS 9.0 · Critical
Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). Skor CVSS 3.1 9.0 (Critical) menurut github.com.
Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.119, the administrator Activity Log in htdocs/js/pages/admin/Activity.js concatenates the attacker-controlled item.user.full_name value into HTML without applying encode_entities and inserts the result through this.div.html. The bundled pixl-server-user input filter can be bypassed by a tag containing a line break because its regular expression does not match newlines. An authenticated non-administrator can update the attacker's own name through /api/user/update using a valid session and current password; when free_accounts is enabled, an anonymous attacker can instead plant the name during self-registration. The stored name executes script in an administrator's session when the Activity Log is opened, enabling administrator takeover and subsequent command execution through privileged Cronicle features. This issue is fixed in version 0.9.119.
