Description

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.

Advisories
GitHub AdvisoryNVD
Paloaltonetworks: A vulnerability affecting most implementations of SSL 3.0 has been discovered that allows an attacker to decrypt some encrypted contents under certain conditions (CVE-2014-3566). The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. More information can be found at: https://www.openssl.org/~bodo/ssl-poodle.pdf. SSL 3.0 is a supported protocol in PAN-OS services including device management and SSL VPN. The conditions of successful exploitation are somewhat similar to the BEAST attack, which requires several conditions to be met for successful exploitation (i.e. the attacker requires a man-in-the-middle position in the network and must also be able to direct the victim client to send many repeated requests to the vulnerable server on behalf of the attacker via scripting, web sockets, or similar mechanism). Due to the conditions required of a successful attack scenario, the risk of exploitation is not particularly high. More information can be found in Microsoft Security Advisory 3009008 (https://technet.microsoft.com/library/security/3009008). This issue affects PAN-OS 6.1.1 and earlier; PAN-OS 6.0.7 and earlier; PAN-OS 5.1.x and PAN-OS 5.0.x.
