(BattleCars Exploit-Rocket League)
Buffer Overflow- [Current system software, Most recent version of application(SYSSW 2.57)/(Rocket League 1.03)]
First block all requests from:https://patch103-dot-psyonix-rl.appspot.com/
When you launch Rocket League it gets a stub file from: http://psyonix-rl-529970.c.cdn77.org/BC2/versions/103/config/BattleCars_Prod/client.bin
You can redirect that to load a huge file and/or a specifly crafted payload instead of the stub. If you use the proper file, it doesn't need to be that large, the example below is under 9mb.
Your file will be loaded into memory, when the file is large enough/a game is played and/or you wait enough time you can consistently cause a buffer overflow and the application will crash.
Depending on how you craft your payload, you may or may not have to do any of that get it working. There are no checks performed at all on file size, content, ect.
Staying on the start screen for long enough can also trigger it. If your payload isn't created properly it will take much longer to execute.
If you are having problems getting this working, you can use the example file, causing an almost instant buffer overflow upon launch of the application.
If your payload is crafted properly, you should be able to get it working withing 10-20 seconds of launching the application . A carefully crafted file may be able to exploit this or similar issues to gain code execution, among other things. It may also be possible to alter gameplay via similar methods.
No payload will be provided at the moment because this is very experimental.
Vidnow (TCP Buffer Overflow)
When you launch Vidnow for the first time it gets http://sceecatalogs.vidzone.tv/386/vidzone_386_US.db.psarc. This file is 5mb. This file loads into a 60k tcp buffer. No checks are done at all on the files size/hash/contents. Therefore, it is possible to redirect Vidnow to load a substitute file. When vidnow is redirected to load a large enough file the TCP Window buffer is overrun,somewhere between byte 34,125,000 and 35,000,000 of the substitute file. Despite the buffer overflow and crash, the substitute data is still transmitted and the application only throws the exception when another tcp packet is sent. As a result, the application crashes and the console locks up for a minute. Directly before the console resumes normal operations after the crash, an unusually large number of tcp (RST) packets are sent. While no exploit that makes use of this crash is currently available, a carefully crafted file may be able to exploit this or similar issues to gain code execution, among other things.

For some reason the system fails to perform any checks/verify certain sys library's before installing them. This allows you to replace those library files with your own binary. The system will install your packaged binary to the HDD as if it were a regular update. In order to run this binary, you need to meet all the requirements listed below.
Running your own code in sandbox requires 4 things:
1.Disabling SHA-1 Checksums ✔ useSha1Checksums = "false" OR -Change SHA-1 checksums to match modified pkg
2.Generate a valid signature/disable or bypass signature authentication ✖ Hash of container + Magic Number form signature -Hash can be computed from modified files -Magic Number = ???
3.Repacking Containers ✔ Lib pkg not signed or encrypted. You can modify everything as long as you don't change the structure.
4.Crafting proper binary ✔ Binary files in sandbox aren't signed or encrypted. If you use the proper version of the compiler (Get the ver info from the original binarys) you can craft a binary that's accepted as valid.
Assuming you can get code running disabling sandboxing is trivial.
Decryption of any post-proto pup
- a bug in the handlers of pup decryption allows for a person with a ps4 on at least 1.62 or below to decrypt any pup (retail, testkit or devkit) with a version above 1.00 (post-proto)
- fixed around 1.70
Decryption of any usermodule self from 1.00 to 3.70
- Sony reused keys from 1.00 to 3.70 on usermodules. as a result, any usermodule from those versions can be decrypted on a ps4 between 1.00 and 3.70
- patched in 4.00 with the introduction of new keyset
Internal table of symbols kept on very low versions
- Sony used to have two tables of symbols on very low versions: internal and external (internal had all symbols, external had 75% of them)
- patched somewhere around 1.05
External table of symbols kept on low versions
- after Sony removed internal table, they still kept the external one
- patched somewhere around 2.50
