This is a dockerized application that is vulnerable (https://www.kitploit.com/search/label/Vulnerable) to the Spring4Shell vulnerability (https://www.kitploit.com/search/label/Vulnerability) (CVE-2022-22965). Full Java source for the war is provided and modifiable, the war will get re-built whenever the docker image is built. The built WAR will then be loaded by Tomcat. There is nothing special about this application, it's a simple hello world that's based off Spring tutorials (https://spring.io/guides/gs/handling-form-submission/). Details: https://www.lunasec.io/docs/blog/spring-rce-vulnerabilitiesHaving issues with the POC? Check out the LunaSec fork at: https://github.com/lunasec-io/Spring4Shell-POC, it's more actively maintained. Requirements Docker Python3 + requests library Instructions Clone the repository Build and run the container: docker build . -t spring4shell && docker run -p 8080:8080 spring4shell App should now be available at http://localhost:8080/helloworld/greeting

Notes Fixed! As of this writing, the container (https://www.kitploit.com/search/label/Container) (possibly just Tomcat) must be restarted between exploitations. I'm actively trying to resolve this. Re-running the exploit will create an extra artifact file of {old_filename}_.jsp. PRs/DMs @Rezn0k (https://twitter.com/rezn0k) are welcome for improvements!

How to spoof caller ID to custom number?

Is there a way I can use a specific number to call someone else? Nothing malicious just wanted to do a light prank calling a friend as another friend.

hacking: security in practice
software distribution sites that check for malware?

Hi all!

I am working on a small hotkey counter program to be the enhanced version of DCSB by being configurable to multiple keys and increment multiple text files

Since this requires use of a global key listener, my guess is it would be flagged by malware software (idk that works really I’m just assuming)? Is there a reputable site that you can upload your software to, where they’ll scan and approve it so your average user can be comfortable downloading and running it?
