VPR Score: 3.4


The remote device is missing a vendor-supplied security patch.


According to its self-reported version number, the remote Junos device is affected by a denial of service vulnerability. A remote attacker, by sending a specially crafted SIP packet to an SRX series device, can crash the 'flowd' process.

Note that this issue only affects SRX series devices when SIP ALG is enabled. All SRX devices, except for SRX-HE devices, have SIP ALG enabled by default.
