New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.6
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version and model number, the remote Juniper Junos device is affected by a denial of service vulnerability in the Application Layer Gateway (ALG) that is triggered when handling a large amount of fragmented packets. An unauthenticated, remote attacker can exploit this to crash an MS-MPC or MS-MIC service physical interface card (PIC).
Note that the device is only vulnerable if NAT or stateful-firewall rules are configured with ALGs enabled
SolutionUpgrade to the relevant Junos software release referenced in Juniper security advisory JSA10794. Alternatively, disable NAT and the stateful-firewall if they are not required.
