What it is

⚠️ A sneaky script injection is hiding in the DNN Persona Bar! If your module's friendly name contains scripts, it could trigger havoc during operations. 🔥 Think of it like a restaurant where the menu allows chefs to sneak in ingredients without anyone checking. If a chef decided to add a dash of something dangerous, it could ruin the whole dish! An attacker could exploit this vulnerability to execute arbitrary scripts, potentially gaining unauthorized access or manipulating module operations. If left unaddressed, it could lead to data breaches or unauthorized actions within your DNN instance! Yikes!

Put simply

Think of it like a restaurant where the menu allows chefs to sneak in ingredients without anyone checking. If a chef decided to add a dash of something dangerous, it could ruin the whole dish! This vulnerability allows for script injection in module friendly names, which are executed during specific operations in the Persona Bar, enabling attackers to run malicious code in the web application context.

What to do

An attacker could exploit this vulnerability to execute arbitrary scripts, potentially gaining unauthorized access or manipulating module operations. If left unaddressed, it could lead to data breaches or unauthorized actions within your DNN instance! Yikes! Update your DNN installation to versions 9.13.10 or 10.2.0 to patch this vulnerability immediately. Also, review the friendly names of your modules and sanitize them to prevent script inclusion in the future. You've got this! Fixing this vulnerability will bolster your security and keep your DNN site safe! 🛡️
