  • CWE-79 - Improper neutralization of input during web page generation ('cross-site scripting')
Summary
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.

CVE-2022-42920 (GCVE-0-2022-42920)
Vulnerability from cvelistv5
Published
2022-11-07 00:00
Modified
2024-08-03 13:19
Severity ?
CWE
Summary
Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to Apache Commons BCEL 6.6.0.
