Jadx-gui vulnerable to swing HTML Denial of Service (DoS) attack
Date: 2022-10
Affected: maven/io.github.skylot:jadx-plugins-api
Attack vector: dos
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2022-39259
CVSS: 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

### Impact Using jadx-gui to open a special zip file with entry containing HTML sequence like `<html><frame>` will cause interface to get stuck and throw exceptions like: ``` java.lang.RuntimeException: Can't build aframeset, BranchElement(frameset) 1,3 :no ROWS or COLS defined. at java.desktop/javax.swing.text.html.HTMLEditorKit$HTMLFactory.create(HTMLEditorKit.java:1387) at java.desktop/javax.swing.plaf.basic.BasicHTML$BasicHTMLViewFactory.create(BasicHTML.java:379) at java.desktop/javax.swing.text.CompositeView.loadChildren(CompositeView.java:112) ``` ### References https://www.oracle.com/java/technologies/javase/seccodeguide.html Guideline 3-7 / INJECT-7: Disable HTML display in Swing components: Many Swing pluggable look-and-feels interpret text in certain components starting with <html> as HTML. If the text is from an untrusted source, an adversary may craft the HTML such that other components appear to be present or to perform inclusion attacks. To disable the HTML render feature, set the "html.disable" client property of each component to Boolean.TRUE (no other Boolean true instance will do). ```java label.putClientProperty("html.disable", true); ```
