Introduction
A Self Cross-Site Scripting (XSS) vulnerability has been identified within the Arduino-IDE prior to version v2.3.5
This type of attack occurs when user input is not properly sanitized and may enable an attacker to deceive a legitimate user into running harmful JavaScript code within the context of the Arduino-IDE application.
Although Self-XSS requires user interaction, often through social engineering tactics, it can still be used to compromise sensitive information or trigger unintended actions in the context of the vulnerable application.
Impact
The vulnerability occurs in the Additional Board Manager URLs field, which can be found in the Preferences -> Settings section of the Arduino IDE interface.
In the vulnerable versions, any values entered in this field are directly displayed to the user through a notification tooltip object, without a proper output encoding routine, due to the underlying ElectronJS engine interpretation.
This vulnerability exposes the input parameter to Self-XSS attacks, which may lead to security risks depending on where the malicious payload is injected.
Patches
The issue has been resolved starting from Arduino IDE version 2.3.5. Please update to at least this version to eliminate the vulnerability.
