So there are some news from the front of OpenSSL CVE-2009-3555 (see this and this for the history). Now the latest version of Apache mod_ssl (2.2) embeds an option to reactivate old way client renegociation : Check the official doc for more details. With this option activated, you can now safely upgrade openSSL and mod_ssl [...]
Recent work of security researchers on SSL MiTM attacks have shown how fragile the whole Internet security design could be. But whereas some of these attacks concerns CA with insufficient security policies (md5 collisions) or some level of social engineering against the user (sslsniff), this paper alerts us on a more serious and stealth threat. [...]
And Google is making so much noise about that ? If what is said is true, it nothing else but a trojan. A good one, but nothing new otherwise. I would also say that the most targeted company was Microsoft. After all, it was an Internet Explorer 0-days breach that was exploited. Once the computer [...]
A solution has been finally brought up to fix CVE-2009-3555 and the temporary solution that broke client authentication. At least, the IETF agreed on a fix as Marsh Ray informs us, though it will still take some weeks for the whole validation process to complete. Moreover, as it requires both the servers and the clients [...]
waf00f is another nice fingerprinting tool. It is a good complement to a tool like httprint. It is able to detect Web Application Firewalls. Its output can help you to determine the trust you can have in what httprint or any other web server fingerprinting tool found out. Check it there.
I finished reading the ModSecurity 2.5 book, written by Magnus Mischell and published by Packt Publishing. I found a lot of interest reading it as I was already using ModSecurity – and I think anyone exposing an Apache web server should. I was actually using it partially. It is not trivial to secure a web [...]
A security advisory on OpenSSL has recently been published. Details are there and there. It is vulnerable to a MiTM attack where the attacker can intercept and retrieve the credential to a trusted HTTPS website, by intercepting the session cookie sent back to the client. A proof of concept of an attack against Twitter was [...]
There will be a new book about mod-security coming out : ModSecurity 2.5. ModSecurity is essential when it comes to secure any web site. It will make the work of the attacker much harder and it may save you even if your favorite dynamic pages have a security hole. However, it must be configured wisely [...]
