For its 18th year the conference took place in the glamorous Mandalay Bay Conference Center in Las Vegas. And as every year, two security analysts of Compass Security have […]

Update – 13.10.2015: Netgear published a new firmware (version 1.1.0.32) which fixes the reported authentication bypass. My most recently appointed colleague, Daniel Haake, described in the previous blog article “Authentication Bypass in Netgear WNR1000v4 Router” how he found an authentication bypass in commonly used Netgear firmwares. Due to the rediscovery of the issue and its […]
Three months ago I tested the web interface of the Netgear WNR1000v4 router for some typical vulnerabilities. When playing around with the application by forcefully calling different URLs in contexts it was not meant for, I got some strange, but interesting behaviour. I accessed different URLs and then switched back to the root web directory […]
Two months ago, we wrote about SAML Raider, a Burp extension which allows automating SAML attacks based on manipulations of the intercepted security assertion. Using this tool, we were able to identify a severe vulnerability in the service provider (SP) implementation of AdNovum‘s nevisAuth. The following conditions make exploitation possible: SAML POST-Binding is used, i.e. […]
During a SharePoint 2013 penetration test I performed last November, I noticed that a dynamically constructed JavaScript constantly fetched content or redirected me to the requested pages. Using a variation of the double-slash trick we exploited in the past, I misused this functionality in order to perform a DOM based open redirection attack. Every SharePoint […]
Ein Hintegrundartikel zur SRF Einstein Sendung vom Donnerstag, 3. September 2015 um 21:00 Uhr zum Thema “Cybercrime, wie sicher ist das Know-how der Schweiz”. (Trailer online) In diesem Artikel zeigen wir Ihnen die Vorgehensweisen von Angreifern auf, die versuchen unerlaubten Zugriff auf fremde Systeme zu erlangen — beispielsweise im Netzwerk eines KMUs. Schematisch sind diese Vorgehensweisen […]
Up to the iPhone 4, 4 digit passcodes could be brute-forced within a short amount of time – maximum 30 minutes, depending on the passcode. With the iPhone 4s, the Boot ROM vulnerability required to upload a custom RAM disk has been closed thus rendering newer phones immune to this attack. This is where the IP-Box […]
At our reoccurring Hacklab days, we at Compass get the chance to hack some stuff of our own choice together for a day. For example playing with GSM in an attempt to send fake SMS or eavesdrop on voice data, comparing Encase capabilities to Unix command line forensic tools or cloning door entry badges in […]
SAML [3] is a standard, which is widely used to deploy Single Sign-On and federation identity solutions. SAML is based on the XML technology, using XML Signatures and X.509 certificates. Manual testing for SAML vulnerabilities is time consuming and error prone. For example, because a SAML message is only valid for a predefined period of […]
