How to Fix CVE-2021-25955

To remediate this vulnerability, upgrade all affected Dolibarr/dolibarr dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dolibarr/dolibarr fixed: 14.0.0 
Upgrade dolibarr/dolibarr to 14.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for dolibarr/dolibarr

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-25955, inspect your project dependencies for Dolibarr/dolibarr:

inspect dependencies for dolibarr/dolibarr

Analyze the terminal output to locate any version of Dolibarr/dolibarr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.0.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Dolibarr/dolibarr, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In `Dolibarr ERP CRM`, WYSIWYG Editor module, v2.8.1 to v13.0.2 are affected by a stored XSS vulnerability that allows low privileged application users to store malicious scripts in the `Private Note` field at `/adherents/note.php?id=1` endpoint. These scripts are executed in a victim’s browser when they open the page containing the vulnerable field. In the worst case, the victim who inadvertently triggers the attack is a highly privileged administrator. The injected scripts can extract the Session ID, which can lead to full Account takeover of the admin and due to other vulnerability (Improper Access Control on Private notes) a low privileged user can update the private notes which could lead to privilege escalation.
