Junos Pulse Access Control Service (UAC): Weak SSL cipher allowed unexpectedly
when higher level cipher group is configured (CVE-2014-3812)
Security Advisories ID: JSA10628
Last Updated: 11 Jun 2014
Version: 3.0
Product Affected:
SA700, SA2500, FIPS SA4000, SA4500, FIPS SA4500, FIPS SA6000, SA6500, FIPS

Problem:
A weak cipher issue has been discovered on the Junos Pulse Secure Access
Service (SSL VPN) and Junos Pulse Access Control Service OS devices. When
configuring the device to use a higher level cipher setting, a lower level
cipher was unexpectedly enabled in error. While clients should always negotiate
the use of the highest available cipher, older clients may have negotiated a
lower and therefore less secure cipher.
