What it is

⚡ Watch out! A low-privilege user can craft a ticket with malicious JavaScript that hijacks admin privileges. How sneaky is that? 🤯 Think of it like a restaurant employee slipping a note into an order that only the chef reads. If the chef takes action without realizing the note is a prank, it could lead to chaos in the kitchen! If an attacker successfully exploits this vulnerability, they could inject scripts that execute with the same privileges as an administrator, leading to unauthorized access and control over sensitive data. Absolutely devastating for any organization using Dolibarr ERP-CRM!

Put simply

Think of it like a restaurant employee slipping a note into an order that only the chef reads. If the chef takes action without realizing the note is a prank, it could lead to chaos in the kitchen! This stored cross-site scripting vulnerability allows low-privilege users to inject malicious scripts into ticket messages, which can run when an admin copies the text, potentially escalating privileges without proper authorization.

What to do

If an attacker successfully exploits this vulnerability, they could inject scripts that execute with the same privileges as an administrator, leading to unauthorized access and control over sensitive data. Absolutely devastating for any organization using Dolibarr ERP-CRM! Update Dolibarr ERP-CRM to version 14.0.3 or later immediately. Additionally, implement strict input validation to sanitize ticket messages and limit JavaScript execution in user inputs. Regular audits of user permissions can also help mitigate risks. You've got this! Follow these steps and you'll have your system secured before you can say 'cross-site scripting'! 🛡️
