high Nessus Plugin ID 207233

Language:

Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco IOS XR is affected by a vulnerability.

- A vulnerability in the multicast traceroute version 2 (Mtrace2) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to exhaust the UDP packet memory of an affected device. This vulnerability exists because the Mtrace2 code does not properly handle packet memory. An attacker could exploit this vulnerability by sending crafted packets to an affected device. A successful exploit could allow the attacker to exhaust the incoming UDP packet memory. The affected device would not be able to process higher-level UDP-based protocols packets, possibly causing a denial of service (DoS) condition.
Note: This vulnerability can be exploited using IPv4 or IPv6. (CVE-2024-20304)
