| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-09-11 | CVE-2024-20390 | Unspecified vulnerability in Cisco IOS XR 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. | 5.3 |
| 2023-10-10 | CVE-2023-44487 | The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | 7.5 |
| 2023-09-13 | CVE-2023-20190 | Incorrect Authorization vulnerability in Cisco IOS XR A vulnerability in the classic access control list (ACL) compression feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to bypass the protection that is offered by a configured ACL on an affected device. This vulnerability is due to incorrect destination address range encoding in the compression module of an ACL that is applied to an interface of an affected device. | 5.3 |
| 2023-09-13 | CVE-2023-20191 | Incorrect Authorization vulnerability in Cisco IOS XR A vulnerability in the access control list (ACL) processing on MPLS interfaces in the ingress direction of Cisco IOS XR Software could allow an unauthenticated, remote attacker to bypass a configured ACL. This vulnerability is due to incomplete support for this feature. | 7.5 |
| 2023-09-13 | CVE-2023-20233 | Improper Validation of Integrity Check Value vulnerability in Cisco IOS XR A vulnerability in the Connectivity Fault Management (CFM) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incorrect processing of invalid continuity check messages (CCMs). | 6.5 |
| 2023-09-13 | CVE-2023-20236 | Insufficient Verification of Data Authenticity vulnerability in Cisco IOS XR A vulnerability in the iPXE boot function of Cisco IOS XR software could allow an authenticated, local attacker to install an unverified software image on an affected device. This vulnerability is due to insufficient image verification. | 7.8 |
| 2023-03-09 | CVE-2023-20049 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Cisco IOS XR A vulnerability in the bidirectional forwarding detection (BFD) hardware offload feature of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers, ASR 9902 Compact High-Performance Routers, and ASR 9903 Compact High-Performance Routers could allow an unauthenticated, remote attacker to cause a line card to reset, resulting in a denial of service (DoS) condition. | 7.5 |
| 2023-03-09 | CVE-2023-20064 | Missing Authorization vulnerability in Cisco IOS XR A vulnerability in the GRand Unified Bootloader (GRUB) for Cisco IOS XR Software could allow an unauthenticated attacker with physical access to the device to view sensitive files on the console using the GRUB bootloader command line. | 4.6 |
| 2022-04-15 | CVE-2022-20758 | Unspecified vulnerability in Cisco IOS XR A vulnerability in the implementation of the Border Gateway Protocol (BGP) Ethernet VPN (EVPN) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. | 6.8 |
| 2021-09-23 | CVE-2021-34714 | Improper Input Validation vulnerability in Cisco products A vulnerability in the Unidirectional Link Detection (UDLD) feature of Cisco FXOS Software, Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. | 7.4 |
