Jenkins Remoting RCE II – The return of the ysoserial

Jenkins Logo

Jenkins is a continuous integration server, widely used in Java environments for building automation and deployment. The project recently disclosed an unauthenticated remote code execution vulnerability discovered by Moritz Bechler. Depending on the development environment, a Jenkins server can be a critical part of the infrastructure: It often creates the application packages that later will be deployed on production application servers. If an attacker can execute arbitrary code, s/he can easily manipulate those packages and inject additional code. Another scenario would be that the attacker stealing credentials, like passwords, private keys that are used for authentication in the deployment process or similar.

Some infos about SAP Security Note 2258786

On the 8th of March SAP released the security note for a vulnerability we reported during an assessment of a SAP landscape. The issue affects the SAP NetWeaver Web Administration Interface.  By knowing a special URL a malicious user can acquire version information about the services enabled in the SAP system as well as the operating system used.  We wanted to share some details on the issue.

VoLTE Security Analysis, part 2

In our talk IMSEcure – Attacking VoLTE Brian and me presented some theoretical and practical attacks against IP Multimedia Subsystems (IMS). Some of the attacks already have been introduced in a former blogpost and Ahmad continued with a deeper analysis of the Flooding and targeted DoS scenario. But still, there are some open topics I’d like to continue with now. The methods I am demonstrating here also help to get a better understanding of VoLTE/IMS and how it is implemented on modern smartphones.

Area41 Conference 2016

Last Friday, Brian and I were at the  Area41 Security Conference. The conference is a branch of Defcon conference and is more or less a small conference of the Swiss hacker community. Being in a “rock music club”, the speakers presented on a stage where usually the rock stars are performing – which gives the conference a very special flair and an interesting atmosphere. We’ve been at the conference to present our research about VoLTE technology including some attack scenarios we’ve evaluated in the past. More on this later, let’s first talk about the conference itself.

SAMLReQuest Burpsuite Extention

Security Assertion Markup Language (SAML) is an XML standard for exchanging authentication and authorization data between a Service Provider (SP) and an  Identification Provider (IdP). SAML is used in many Single Sign-On (SSO) implementations, when a user is authenticated once by IdP to access multiple related SPs. When a user requests to access a SP, it creates a SAML Authentication Request and redirects the user to IdP to be authenticated according to this authentication request. If the user is successfully authenticated, IdP creates a SAML authentication response and sends it back to SP through the user’s browser.

The ULIN Story

Some of you might have noticed the articles, or the leaked manual itself, about a tool called ULIN. ULIN is a “bleeding-edge spy tool” for mobile communication networks. According to the manual, it is aimed to be a surveillance software for agencies (or others with enough money) for tracking and intercepting the Voice Calls and SMS of arbitrary phones. They call this “remote recording and geolocation of mobile handsets using 2G/3G/4G networks”.

New Methods for Exploiting ORM Injections in Java Applications (HITB16)

The HITBSecConf or “Hack In The Box” in Amsterdam is a well known security conference in Europe. We also attended this year too, and there were quite some interesting talks at the HITBSecConf16 conference. One of the talks was about “New Methods for Exploiting ORM Injections in Java Applications” by the security researchers Mikhail Egorov and Sergey Soldatov.

Implementing an Obsolete VPN Protocol on Top of HTTP: Because Why Not?

Recently I’ve started some research on MikroTik’s RouterOS, the operating system that ships with RouterBOARD devices. As I’m running such a device myself, one day I got curious about security vulnerabilities that have been reported on the operating system and the running services as it comes with tons of features. Searching for known vulnerabilities in RouterOS on Google doesn’t really yield a lot of recent security related stuff. So I thought, there is either a lack of (public) research or maybe it is super secure… 🙂

Not really satisfied with the outcome of my research about previous research one day I thought I give it a shot and just take a quick look at the management interfaces, mainly the web interface. As it turns out, there could be a third explanation for the lack of security related search results on Google: obfuscation. The communication of the web interface is obfuscated, most likely encrypted, which may discourages researchers that just came around to search for low hanging fruits.
