CVE-2024-23188 - E-Mail Attachment Name Script Execution Vulnerability Allows Attackers To Perform Malicious API Requests

A new vulnerability (CVE-2024-23188) has been discovered that could lead to malicious attackers temporarily executing script code in the context of a user's browser session via e-mail attachment names. This vulnareability requires common user interaction in order to be triggered, which means that most users may be at risk. In order to protect yourself against this new threat, it is important to deploy the latest updates and patch releases to ensure your data and personal information remains secure.

The malicious code could look something like this

// Malicious attachment name
const payload = "onmouseover='performMaliciousAPIRequest()' ";

// Attacker creates an HTML element with the malicious payload in the e-mail
