During the HITB2017AMS talk given in Amsterdam with  @Steventseeley , I promised that I would have disclosed vulnerabilities affecting a security vendor product other than Trend Micro. For those who have come to my blog for the first time and are looking at "insecurities" of security vendors, you might be interested as well on how we found 200+ remote code execution vulnerabilities in Trend Micro software ... But this blog post is dedicated to two McAfee products instead: McAfee Endpoint Security and SiteAdvisor Enterprise (now part of McAfee Endpoint Security). For simplicity, I will just refer to McAfee Endpoint Security for the rest of this post. First let's demonstrate a particular type of XSS, a UXSS, considering that fact that it only affects the McAfee Endpoint Security plugin and does not depend on a particular web site or web application. There are two different injection points: - UXSS when user visits a red labelled web site - the payload is rendere

In the last few months, I have been testing several Trend Micro products with Steven Seeley ( @steventseeley ). Together, we have found more than 200+ RCE (Remote Code Execution) vulnerabilities and for the first time we presented the outcome of our research at Hack In The Box 2017 Amsterdam  in April. The presentation is available as a PDF or as a Slideshare . Since it was not possible to cover all discovered vulnerabilities with a single presentation, this blog post will cover and analyze a further vulnerability that did not make it to the slides, and which affects the Trend Micro Threat Discovery Appliance (TDA) product. CVE-2016-8584 - TDA Session Generation Authentication Bypass This was an interesting vulnerability, discovered after observing that two consecutive login attempts against the web interface returned the same session_id token. Following this observation, our inference was that time factor played a role. After further analysis and reversing of the TDA libra
