Summary

Apache Commons BCEL before 6.13.0 is affected. Its Class2HTML emitters write strings from class files into generated HTML without escaping them (CWE-79). An unauthenticated attacker who supplies a crafted class file can inject script that runs in the browser of a user who views the generated report.

Description from the CNA

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Apache Commons BCEL. This only happens when you're using Class2HTML to generate webpages for possibly-attacker-controlled class files, where Class2HTML emitters write attacker class-file strings into HTML unescaped (stored XSS in reports). This issue affects Apache Commons BCEL: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue.
