martinez | Last updated: Mar 03, 2021 09:08AM UTC

Hello, I'm just in the middle of your great academy and I found out that some labs in the insecure deserialization part doesn't work. Specifically: Lab: Using application functionality to exploit insecure deserialization Lab: Modifying serialized data types Lab: Arbitrary object injection in PHP Lab: Exploiting Java deserialization with Apache Commons Lab: Exploiting PHP deserialization with a pre-built gadget chain Lab: Exploiting Ruby deserialization using a documented gadget chain Lab: Developing a custom gadget chain for Java deserialization Lab: Developing a custom gadget chain for PHP deserialization Lab: Using PHAR deserialization to deploy a custom gadget chain I always get redirected to the https://portswigger.net/error page.

Hi, We experienced an issue that meant the Web Academy labs were not available to our users. The issue should now be fixed and all of the labs should now be available.

When I was editing the cookie, it shows: Input byte array has incorrect ending byte at 80

Hi, Are you able to confirm the name of the lab that you are having issues with so that we can take a look at this for you?
