Vulnerability in TLS Could Allow Information Disclosure (2655992) (uncredentialed check)

medium Nessus Plugin ID 60016

Language:

Synopsis

It may be possible to obtain sensitive information from the remote host with TLS-enabled services.

Description

The remote TLS server does not verify block cipher padding when using a cipher suite that employs a block cipher such as AES and DES. The lack of padding checking can allow encrypted TLS traffic to be decrypted. This vulnerability could allow for the decryption of HTTPS traffic by an unauthorized third party.

Solution

Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.

For other TLS implementations, contact the vendor for update.
