SIPVicious PRO 6.0.0-beta.4 getting close to take-off!

This one’s a bit of a boring update for SIPVicious PRO. That’s because we’re getting to a stable place where flag names and values do not change too often. Which means, we’re getting out of beta rather soon! However, it is still a major update because we made a significant number of internal changes. For example, we standardized a number of flags to be the same across all tools. We discovered that we can minimize each tool’s flagset by making use of config flags such as --auth-config that allows you to configure behaviours specific to how SIPVicious handles authentication (e.…

OpenSIPIt'01: Lessons learned, STIR/SHAKEN security testing and RFC 8760

Published on Apr 16, 2021

Executive summary (TL;DR) It was a great event, highly recommended if you’re a SIP developer. We developed new STIR/SHAKEN capabilities in SIPVicious PRO. And we found some vulnerabilities during the event that got fixed in the process. What was OpenSIPIt#01 about? This week the humble security researchers from Enable Security participated in OpenSIPIt#01, an online event run by the community to test interoperability across various independent open-source SIP implementations especially when it comes to new RFCs.…

VoIPmonitor advisories: buffer overflow leading to RCE + XSS vulnerabilities

Published on Mar 15, 2021

VoIPmonitor released updates to both the sniffer component and the web application to address vulnerabilities that your favourite Enable Security researchers identified and reported. The sniffer component had a buffer overflow flaw that we actually abused to run arbitrary code (yes, in 2021!). The web application, on the other hand, was vulnerable to cross-site scripting introduced through SIP messages with XSS payloads - which is pretty bad. And so, we just released three advisories to provide further details so that organisations using this software can make better informed decisions.…

SIPVicious PRO 6.0.0-beta.2 takes STDIN and fixes various bugs

What we’re excited about in this minor update is the addition of a new feature to the SIP cracker in SIPVicious PRO. Basically, it now takes input from external tools through standard input. Why? Because it allows infinite ways of generating potential usernames, passwords and/or SIP extensions when making use of external tools such as the maskprocessor included in the well known password cracker, hashcat. Here’s an animation showing usage of the maskprocessor to generate passwords for the SIP online cracking tool:…

How doing QA testing for SIPVicious PRO led to an Asterisk DoS
