About this event

Dear Members,

We are pleased to announce the next meetup on-site dedicated to Hacking Java Web Applications.

The speaker is Panos Petsanas, Community CTFs from Hackthebox.

The event will be held in English and is organized by VOID Software with Hackthebox as partner.

This workshop will showcase a case study of an application vulnerable to the infamous log4shell exploit, where the RCE cannot be directly triggered due to the updated Java version that disables remote loading of classes from arbitrary URL code bases. Together we’ll learn how to utilise LDAP serialised objects for deserialisation via JNDI lookup injection and construct custom Java gadget chains.

Let’s meet at the VOID Academy, floor 3 at the Centro Comercial Dom Dinis, 301, Leiria, with an entrance through the parking lot.

The talks will last from 18h30 to 20h00 with a Cocktail at the end. The event is free and requires inscription on Meetup,

The number of places is limited to guarantee the good organization of the event, please make sure to confirm your presence :)

Thanks in advance for your participation and help in sharing the event.

Hoping to see you there!
