Cisco IOS XR Software vulnerabilities

A vulnerability in Multicast Source Discovery Protocol (MSDP) ingress packet processing for Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the MSDP session to be unexpectedly reset, leading to a short denial of service (DoS) condition. The MSDP session will restart within a few seconds.

A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to execute arbitrary code at the root privilege level on an affected system, due to Incorrect Permissions.

A vulnerability in the HTTP 2.0 request handling code of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the Event Management Service daemon (emsd) to crash, resulting in a denial of service (DoS) condition.

A vulnerability in Cisco IOS XR Software was discovered during an internal security review. It relates to improper checking or handling of exceptional conditions, classified as CWE-703.

A vulnerability in Cisco IOS XR Software was discovered during an internal security review. It relates to improper neutralization issues, classified as CWE-707.

A vulnerability in Cisco IOS XR Software was discovered during an internal security review. It relates to protection mechanism failure issues, classified as CWE-693.

A vulnerability in Cisco IOS XR Software was discovered during an internal security review. It relates to insufficient control flow management issues, classified as CWE-691.

A vulnerability in Cisco IOS XR Software was discovered during an internal security review. It relates to incorrect calculation issues, classified as CWE-682.

A vulnerability in the IS-IS multi-instance routing feature of Cisco IOS XR Software allows an unauthenticated, adjacent attacker to cause an unexpected restart of the IS-IS process. The issue is due to insufficient input validation of incoming IS-IS packets.

A vulnerability in Cisco IOS XR Software allows a local attacker with low privileges to elevate privileges to full administrative control over the device. The issue stems from incorrect mapping of a CLI command to task groups in the source code.

A vulnerability in the CLI of Cisco IOS XR Software allows an authenticated local attacker to execute arbitrary commands as root on the underlying operating system. This is due to insufficient validation of user arguments passed to specific CLI commands.

A vulnerability in the installation process of Cisco IOS XR Software could allow an authenticated, local attacker to bypass image signature verification and load unsigned software. This is due to incomplete validation of files during .iso installation.

A vulnerability in the management interface access control list (ACL) processing feature in Cisco IOS XR Software could allow an unauthenticated, remote attacker to bypass configured ACLs for the SSH, NetConf, and gRPC features. This occurs because management interface ACLs are not supported on Packet I/O infrastructure platforms for Linux-handled features.
