During a recent penetration test we found and exploited various issues in Observium, a popular networking monitoring platform. The vulnerabilities lead us from unauthenticated user to full shell access as root.
In this blog we’ll look at an interesting vulnerability in some implementations of a widely used authentication protocol; Secure Remote Password (SRP). We’ll dive into the cryptography details to see what implications a little mathematical oversight has for the security of the whole protocol.
Recently, we found a critical vulnerability in StartCom’s new StartEncrypt tool, that allows an attacker to gain valid SSL certificates for domains he does not control. While there are some restrictions on what domains the attack can be applied to, domains where the attack will work include google.com, facebook.com, live.com, dropbox.com and others.
