Juniper ScreenOS 6.2.x < 6.2.0r19 / 6.3.x < 6.3.0r21 Multiple Vulnerabilities (JSA10713)

Critical Nessus Plugin ID 87507


The remote host is affected by multiple vulnerabilities.


The remote host is running a version of Juniper ScreenOS that is 6.2.x prior to 6.2.0r19 or 6.3.x prior to 6.3.0r21. It is, therefore, affected by multiple vulnerabilities :

- A backdoor exists that allows a remote attacker administrative access to the device over SSH or telnet.

- An unspecified flaw exists that allows a man-in-the-middle attacker to decrypt VPN traffic.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Juniper ScreenOS 6.2.0r19 / 6.3.0r21 or later.
Alternatively, apply the appropriate patch referenced in the vendor advisory.
