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: 5.2
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version, IOS-XR is affected by a denial of service (DoS) vulnerability in the ingress packet processing function due to improper resource allocation when processing network traffic in software switching mode (punted). An unauthenticated, remote attacker can exploit this, by sending specific streams of Layer 2 or Layer 3 protocol data units (PDUs) to an affected device, in order to cause a DoS condition on the device.
