Final - SSL/TLS renegotiation explained (CVE-2009-3555)

Final release for my paper explaining the different attack vectors and impacts for (CVE-2009-3555) "TLS / SSL renegotiation vulnerability".

• Added comments and corrections by Alun Jones (Who I hereby thank for his time)
• Changed FTPS description
• Better PDF output

I profit from the update to stress particular impacts that seem to be forgotten about, in addition to the plain-text injection described everywhere (Please refer to the paper to know more)

Additional Impacts

• Potentially allows to downgrade from HTTPS to HTTP (à la SSLstrip)
• Potentially allows to inject XSS into Trace requests

Available Tools (2011)

• My own 2 Proof of concepts
• Red-Team Pentesting Proof of Concept
• Openssl (How-to available in the paper)

I have been delighted by the interest given to this paper at the time, the paper is referenced by the US-CERT, DFN-CERT, BELNET-CERT, SWITCH-cert, Nessus, Qualys, c't Heise and the book "IPhone and IOS Forensics: Investigation, Analysis and Mobile Security" covers the analysis on Page 110
