SonicWall SRA and SMA vulnerabilities

Last year, Orange Tsai did some awesome research and discovered several vulnerabilities in SSL VPN providers which can allow an attacker to break into a network through the very device which is supposed to protect it. The vulnerable constructors were:

Palo Alto
Fortinet
Pulse Secure

Numerous Swiss domain names temporarily hijacked

Last Friday at around 14:05 we noticed that our website (www.scrt.ch) along with some other services we use internally were no longer accessible. We immediately tried to figure out why that was and quickly noticed that our DNS requests were not returning the correct IP addresses.

A pentester’s take on (Not)Petya

By now, everybody has probably read many articles on the latest viral outbreak, ranging from detailed analysis of the virus itself to rants about why companies don’t apply updates in a timely fashion and why employees continue to open malicious attachments in emails.

Heap Overflow Vulnerability in Citrix NetScaler Gateway (CVE-2017-7219)

After presenting my findings on the Swisscom router at the CybSecConference last year, I started looking for a new product to analyze. I quickly found that it’s possible to download virtual “demo” appliances of Citrix products, so I went on to download a Netscaler VPX, which at the time was at version 11.10 (b50.10). The goal as always was to discover a way to compromise the device remotely, which is what led me to discover a heap overflow vulnerability which allows an authenticated user to compromise the device with root privileges. During the research, I (un)fortunately wasn’t able to find a way to exploit the flaw without credentials.
