The moment, when your team leader asks you to cheat at Pokémon GO…everyone knows it, right? No? Well, I do 😉
As I’m not a gamer, the technical part was of much more interest – that’s the real gaming for me.
So, challenge accepted!

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.

Continue readingOn 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.

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.

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.

Continue readingSome 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”.

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.

As you may have already noticed, Cisco released an urgent security advisory describing an IPv6 Neighbor Discovery DoS Vulnerability in several flavors of Cisco’s operating systems. Currently IOS-XR, XE and NX-OS are affected while ASA and “classic” IOS are under investigation. At first glance, it might look like yet another IPv6 DoS vulnerability. Looking closer, Cisco is mentioning an unauthenticated, remote attacker due to insufficient processing logic for crafted IPv6 NDP packets that are sent to an affected device. Following the public discussion about the vulnerability, it seems that these packets will reach the, probably low rate-limited, LPTS filter/queue on IOS XR devices “crowding” out legitimate NDP packets resulting in a DoS for IPv6 traffic, or in general a high CPU load as these packets will be processed by the CPU. More details are currently not available, but this might indicate the affected systems aren’t doing proper message validation checks on NDP packets (in addition to the LPTS filter/queue problem).

A quick update: earlier in our blog we released BMC BladeLogic: CVE-2016-1542 and CVE-2016-1543 vulnerabilities. Now the exploits are also available in our github if you want to check your systems 😉
Have a nice week,
