Juniper ScreenOS 6.2.x < 6.2.0r19 / 6.3.x < 6.3.0r21 Multiple Vulnerabilities (JSA10713)
Critical Nessus Plugin ID 87507
SynopsisThe remote host is affected by multiple vulnerabilities.
DescriptionThe 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.
SolutionUpgrade to Juniper ScreenOS 6.2.0r19 / 6.3.0r21 or later.
Alternatively, apply the appropriate patch referenced in the vendor advisory.
