Juniper ScreenOS 6.3.x < 6.3.0r21 Malformed SSL/TLS Packet DoS (JSA10732)
High Nessus Plugin ID 90708
SynopsisThe remote host is affected by a denial of service vulnerability.
DescriptionThe remote host is running a version of Juniper ScreenOS that is 6.3.x prior to 6.3.0r21. It is, therefore, affected by a denial of service vulnerability in the administrative web services that is triggered when handling malformed SSL/TLS packets. An unauthenticated, remote attacker can exploit this, via a crafted SSL packet, to cause the loss of administrative access or to reboot the system.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Juniper ScreenOS version 6.3.0r21 or later.
