Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Grumpydictator/firefly iii, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Firefly III before 4.7.17.1 is vulnerable to stored XSS due to lack of filtration of user-supplied data in a budget name. The JavaScript code is contained in a transaction, and is executed on the tags/show/$tag_number$ tag summary page. NOTE: It is asserted that an attacker must have the same access rights as the user in order to be able to execute the vulnerability
