CVE-2024-20467 1 Cisco 1 Ios Xe 2026-06-17 N/A 8.6 HIGH
A vulnerability in the implementation of the IPv4 fragmentation reassembly code in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper management of resources during fragment reassembly. An attacker could exploit this vulnerability by sending specific sizes of fragmented packets to an affected device or through a Virtual Fragmentation Reassembly (VFR)-enabled interface on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Note: This vulnerability affects Cisco ASR 1000 Series Aggregation Services Routers and Cisco cBR-8 Converged Broadband Routers if they are running Cisco IOS XE Software Release 17.12.1 or 17.12.1a.
CVE-2024-20466 1 Cisco 1 Identity Services Engine 2026-06-17 N/A 6.5 MEDIUM
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to obtain sensitive information from an affected device. This vulnerability is due to improper enforcement of administrative privilege levels for high-value sensitive data. An attacker with read-only Administrator privileges for the web-based management interface on an affected device could exploit this vulnerability by browsing to a page that contains sensitive data. A successful exploit could allow the attacker to collect sensitive information regarding the configuration of the system.
CVE-2024-20465 1 Cisco 1 Ios 2026-06-17 N/A 5.8 MEDIUM
A vulnerability in the access control list (ACL) programming of Cisco IOS Software running on Cisco Industrial Ethernet 4000, 4010, and 5000 Series Switches could allow an unauthenticated, remote attacker to bypass a configured ACL. This vulnerability is due to the incorrect handling of IPv4 ACLs on switched virtual interfaces when an administrator enables and disables Resilient Ethernet Protocol (REP). An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device.
CVE-2024-20464 1 Cisco 1 Ios Xe 2026-06-17 N/A 8.6 HIGH
A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of received IPv4 PIMv2 packets. An attacker could exploit this vulnerability by sending a crafted PIMv2 packet to a PIM-enabled interface on an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition. Note: This vulnerability can be exploited with either an IPv4 multicast or unicast packet.

CVE-2024-20457 1 Cisco 1 Unified Communications Manager Im And Presence Service 2026-06-17 N/A 6.5 MEDIUM
A vulnerability in the logging component of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system. This vulnerability is due to the storage of unencrypted credentials in certain logs. An attacker could exploit this vulnerability by accessing the logs on an affected system and obtaining credentials that they may not normally have access to. A successful exploit could allow the attacker to access sensitive information from the device.
CVE-2024-20456 1 Cisco 59 8011-4g24y4h-i, 8101-32fh, 8101-32fh-o and 56 more 2026-06-17 N/A 6.7 MEDIUM
A vulnerability in the boot process of Cisco IOS XR Software could allow an authenticated, local attacker with high privileges to bypass the Cisco Secure Boot functionality and load unverified software on an affected device. To exploit this successfully, the attacker must have root-system privileges on the affected device. This vulnerability is due to an error in the software build process. An attacker could exploit this vulnerability by manipulating the system’s configuration options to bypass some of the integrity checks that are performed during the booting process. A successful exploit could allow the attacker to control the boot configuration, which could enable them to bypass of the requirement to run Cisco signed images or alter the security properties of the running system.
CVE-2024-20455 1 Cisco 2 Ios Xe, Ios Xe Sd-wan 2026-06-17 N/A 8.6 HIGH
A vulnerability in the process that classifies traffic that is going to the Unified Threat Defense (UTD) component of Cisco IOS XE Software in controller mode could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability exists because UTD improperly handles certain packets as those packets egress an SD-WAN IPsec tunnel. An attacker could exploit this vulnerability by sending crafted traffic through an SD-WAN IPsec tunnel that is configured on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Note: SD-WAN tunnels that are configured with Generic Routing Encapsulation (GRE) are not affected by this vulnerability.
