| A vulnerability in the access control list (ACL) programming of Cisco IOS XE Software for Cisco Catalyst 9500X and 9600X Series Switches could allow an unauthenticated, remote attacker to bypass a configured ACL on an affected device.
This vulnerability is due to the flooding of traffic from an unlearned MAC address on a switch virtual interface (SVI) that has an egress ACL applied. An attacker could exploit this vulnerability by causing the VLAN to flush its MAC address table. This condition can also occur if the MAC address table is full. A successful exploit could allow the attacker to bypass an egress ACL on an affected device. |
| A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker with administrative privileges to execute arbitrary commands as root on the underlying operating system of an affected device.
This vulnerability is due to insufficient validation of user arguments that are passed to specific CLI commands. An attacker could exploit this vulnerability by logging in to the device CLI with valid administrative (level 15) credentials and using crafted commands at the CLI prompt. A successful exploit could allow the attacker to execute arbitrary commands as root. |
| A vulnerability in the VPN web server of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker to execute arbitrary code on an affected device.
This vulnerability is due to improper validation of user-supplied input in HTTP(S) requests. An attacker with valid VPN user credentials could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as root, possibly resulting in the complete compromise of the affected device. |
| A vulnerability in specific CLI commands in Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. To exploit this vulnerability, the attacker must have valid Administrator privileges on an affected device.
This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a crafted CLI command. A successful exploit could allow the attacker to elevate privileges to root. |
| A vulnerability in the HTTP API subsystem of Cisco IOS XE Software could allow a remote attacker to inject commands that will execute with root privileges into the underlying operating system.
This vulnerability is due to insufficient input validation. An attacker with administrative privileges could exploit this vulnerability by authenticating to an affected system and performing an API call with crafted input. Alternatively, an unauthenticated attacker could persuade a legitimate user with administrative privileges who is currently logged in to the system to click a crafted link. A successful exploit could allow the attacker to execute arbitrary commands as the root user. |
| A vulnerability in the Device Analytics action frame processing of Cisco Wireless Access Point (AP) Software could allow an unauthenticated, adjacent attacker to inject wireless 802.11 action frames with arbitrary information.
This vulnerability is due to insufficient verification checks of incoming 802.11 action frames. An attacker could exploit this vulnerability by sending 802.11 Device Analytics action frames with arbitrary parameters. A successful exploit could allow the attacker to inject Device Analytics action frames with arbitrary information, which could modify the Device Analytics data of valid wireless clients that are connected to the same wireless controller. |
| A vulnerability in the access control list (ACL) processing of IPv4 packets of Cisco SD-WAN vEdge Software could allow an unauthenticated, remote attacker to bypass a configured ACL.
This vulnerability is due to the improper enforcement of the implicit deny all at the end of a configured ACL. An attacker could exploit this vulnerability by attempting to send unauthorized traffic to an interface on an affected device. A successful exploit could allow the attacker to bypass an ACL on the affected device. |
| A vulnerability in the Address Resolution Protocol (ARP) implementation of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to trigger a broadcast storm, leading to a denial of service (DoS) condition on an affected device.
This vulnerability is due to how Cisco IOS XR Software processes a high, sustained rate of ARP traffic hitting the management interface. Under certain conditions, an attacker could exploit this vulnerability by sending an excessive amount of traffic to the management interface of an affected device, overwhelming its ARP processing capabilities. A successful exploit could result in degraded device performance, loss of management connectivity, and complete unresponsiveness of the system, leading to a DoS condition. |
| A vulnerability in the installation process of Cisco IOS XR Software could allow an authenticated, local attacker to bypass Cisco IOS XR Software image signature verification and load unsigned software on an affected device. To exploit this vulnerability, the attacker must have root-system privileges on the affected device.
This vulnerability is due to incomplete validation of files during the installation of an .iso file. An attacker could exploit this vulnerability by modifying contents of the .iso image and then installing and activating it on the device. A successful exploit could allow the attacker to load an unsigned file as part of the image activation process. |
| 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 vulnerability exists because management interface ACLs have not been supported on Cisco IOS XR Software Packet I/O infrastructure platforms for Linux-handled features such as SSH, NetConf, or gRPC. An attacker could exploit this vulnerability by attempting to send traffic to an affected device. A successful exploit could allow the attacker to bypass an ingress ACL that is applied on the management interface of the affected device. |
| A vulnerability in the Hot Standby Router Protocol (HSRP) subsystem of Cisco IOS and IOS XE Software could allow an unauthenticated, adjacent attacker to receive potentially sensitive information from an affected device. The vulnerability is due to insufficient memory initialization. An attacker could exploit this vulnerability by receiving HSRPv2 traffic from an adjacent HSRP member. A successful exploit could allow the attacker to receive potentially sensitive information from the adjacent device. |
| A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition. |
| A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) Software and Cisco Unified CM Session Management Edition (SME) Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected device.
This vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user. |
| A vulnerability in the user profile component of Cisco Webex Meetings could have allowed an authenticated, remote attacker with low privileges to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.
This vulnerability existed because of insufficient validation of user-supplied input to the user profile component of Cisco Webex Meetings. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could have allowed the attacker to conduct an XSS attack against the targeted user. |
| A vulnerability in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.

A successful exploit could allow the attacker to access sensitive files from the affected device. |
| A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the interface of an affected system.
This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious code into specific data fields in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker must have valid administrative credentials. |
| A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, remote attacker to obtain sensitive information from an affected system.
This vulnerability is due to improper validation of requests to API endpoints. An attacker could exploit this vulnerability by sending a valid request to a specific API endpoint within the affected system. A successful exploit could allow a low-privileged user to view sensitive configuration information on the affected system that should be restricted. To exploit this vulnerability, an attacker must have access as a low-privileged user. |
| A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, remote attacker to upload arbitrary files to an affected device.
This vulnerability is due to improper validation of files that are uploaded to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted file upload request to a specific API endpoint. A successful exploit could allow the attacker to upload arbitrary files to an affected system. To exploit this vulnerability, an attacker must have at least valid Config Managers credentials on the affected device. |
| A vulnerability in Cisco Webex Meetings could have allowed an unauthenticated, remote attacker to redirect a targeted Webex Meetings user to an untrusted website. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed.
This vulnerability existed because of insufficient validation of URLs that were included in a meeting-join URL. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by including a URL to a website of their choosing in a specific value of a Cisco Webex Meetings join URL. A successful exploit could have allowed the attacker to redirect a targeted user to a website that was controlled by the attacker, possibly making the user more likely to believe the website was trusted by Webex and perform additional actions as part of phishing attacks. |
