Go-pandoc - LUA filter remote code execution

by Denis Andzakovic • Jan 29 2019

Go-pandoc is vulnerable to remote code execution through a user included LUA filter. An attacker can upload a LUA file to a known location on the file system due to a predictable temporary directory being used when handling certain file type includes. The uploaded LUA file can then be used as a filter in a subsequent request, allowing for the execution of arbitrary LUA code.

Adventures with the Ducati CAN bus

by Denis Andzakovic • Nov 12 2018

In this article I’ll be taking a look at the CAN bus network in a 2009 Ducati 848. How to find the bus, confirm the high and low lines with a scope and analyse messages with a Linux box and socket-CAN. The aim of the game is to identify a way to get onto the bus, and then analyse the messages going across the bus. We’ll end up figuring out how to log the throttle position and RPM data, how the immobilizer is implemented and how to bypass it.

Oracle WebLogic - Multiple SAML Vulnerabilities (CVE-2018-2998/CVE-2018-2933)

by Denis Andzakovic • Jul 18 2018

Two vulnerabilities were discovered within the Oracle WebLogic SAML service provider authentication mechanism. By inserting an XML comment into the SAML NameID tag, an attacker can coerce the SAML service provider to log in as another user. Additionally, WebLogic does not require signed SAML assertions in the default configuration. By omitting the signature portions from a SAML assertion, an attacker can craft an arbitrary SAML assertion and bypass the authentication mechanism.
