CVE-2024-20304 – Cisco IOS XR Software Packet Memory Exhaustion Vulnerability
https://notcve.org/view.php?id=CVE-2024-20304
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. ... 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. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-pak-mem-exhst-3ke9FeFy • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2024-20406 – Cisco IOS XR Software Intermediate System-to-Intermediate System Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20406
A vulnerability in the segment routing feature for the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of ingress IS-IS packets. ... A successful exploit could allow the attacker to cause the IS-IS process on all affected devices that are participating in the Flexible Algorithm to crash and restart, resulting in a DoS condition. Note: The IS-IS protocol is a routing protocol. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-isis-xehpbVNe • CWE-20: Improper Input Validation •
CVE-2024-20317 – Cisco IOS XR Software Layer 2 Services Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20317
A vulnerability in the handling of specific Ethernet frames by Cisco IOS XR Software for various Cisco Network Convergence System (NCS) platforms could allow an unauthenticated, adjacent attacker to cause critical priority packets to be dropped, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect classification of certain types of Ethernet frames that are received on an interface. An attacker could exploit this vulnerability by sending specific types of Ethernet frames to or through the affected device. A successful exploit could allow the attacker to cause control plane protocol relationships to fail, resulting in a DoS condition. For more information, see the section of this advisory. Cisco has released software updates that address this vulnerability. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-l2services-2mvHdNuC • CWE-684: Incorrect Provision of Specified Functionality •
CVE-2024-20390 – Cisco IOS XR Software Dedicated XML Agent TCP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20390
A vulnerability in the Dedicated XML Agent feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) on XML TCP listen port 38751. This vulnerability is due to a lack of proper error validation of ingress XML packets. An attacker could exploit this vulnerability by sending a sustained, crafted stream of XML traffic to a targeted device. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-xml-tcpdos-ZEXvrU2S • CWE-940: Improper Verification of Source of a Communication Channel •
CVE-2024-4465 – Incorrect authorization for Reports configuration in Guardian/CMC before 24.2.0
https://notcve.org/view.php?id=CVE-2024-4465
This could result in a partial loss of data integrity. In Guardian/CMC instances with a reporting configuration, there could be limited Denial of Service (DoS) impacts, as the reports may not reach their intended destination, and there could also be limited information disclosure impacts. ... This could result in a partial loss of data integrity. In Guardian/CMC instances with a reporting configuration, there could be limited Denial of Service (DoS) impacts, as the reports may not reach their intended destination, and there could also be limited information disclosure impacts. ... This could expand the scope of the attack. • https://security.nozominetworks.com/NN-2024:2-01 • CWE-863: Incorrect Authorization •
