HP released a security bulletin and mitigation technique to address SSL-TLS implementations affected by the Cipher Block Chaining padding information disclosure vulnerability.
Attacks exploiting this vulnerability are identified as Padding Oracle On Downgraded Legacy Encryption (POODLE) attacks, which could be used to disclose HTTP cookies or other HTTP authorization content that is being transmitted over an TLSv1.x secure session. This issue should not be confused with CVE-2014-3566, as described in Cisco IntelliShield Alert 36084.
It should be noted that oracle does not refer to the software company of the same name, but to a term used in cryptography.
To exploit the vulnerability, the attacker may require access to a trusted, internal network to perform man-in-the-middle attacks on a targeted system. This access requirement limits the likelihood of a successful exploit.
Version 4, May 29, 2015, 9:25 AM: Cisco has released software and fix information for additional products affected by the SSL-TLS implementations Cipher Block Chaining padding information disclosure vulnerability.
Version 3, December 26, 2014, 8:49 AM: IBM has released a security bulletin and fixes to address the SSL-TLS implementations Cipher Block Chaining padding information disclosure vulnerability.
Version 2, December 17, 2014, 11:54 AM: IntelliShield has updated this alert to include Snort signature information. Cisco has released a security notice to address the SSL-TLS implementations Cipher Block Chaining padding information disclosure vulnerability.
Version 1, December 11, 2014, 2:21 PM: TLSv1.x implementations may contain a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information. Updates are available.Show Less
