## What is CVE-2024-52597?

CVE-2024-52597 is a medium-severity cross-site scripting vulnerability in Bubka 2FAuth, published on 20 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Versions prior to 5.4.1 are vulnerable to stored cross-site scripting due to improper headers in direct access to uploaded SVGs. The application allows uploading images in several places. One of the accepted types of image is SVG, which allows JS scripting. Therefore, by uploading a malicious SVG which contains JS code, an attacker which is able to drive a victim to the uploaded image could compromise that victim's session and access to their tokens. Version 5.4.1 contains a patch for the issue.

Weakness: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page), CWE-79 (Improper Neutralization of Input During Web Page Generation)
