Title
Cisco IOS Software and IOS XE Software Extensible Messaging Client Protocol Denial of Service Vulnerability
Summary
A vulnerability in the Extensible Messaging Client Protocol (XMCP), also referred to as the External Client protocol, of Cisco IOS Software and 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 handling of malformed XMCP packets. An attacker could exploit this vulnerability by sending a malformed XMCP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. The attacker does not need the XMCP client username to exploit this vulnerability.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

Title
Cisco IOS XE Software SNMP Denial of Service Vulnerability
Summary
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.
This vulnerability is due to improper error handling when parsing SNMP requests. This vulnerability affects all versions of SNMP — Versions 1, 2c, and 3. An attacker could exploit this vulnerability by sending a malformed SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly.

CVE-2026-20114 (GCVE-0-2026-20114)
Vulnerability from nvd – Published: 2026-03-25 16:08 – Updated: 2026-03-25 17:34

VEX
Summary
A vulnerability in the Lobby Ambassador web-based management API of Cisco IOS XE Software could allow an authenticated, remote attacker to elevate their privileges and access management APIs that would not normally be available for Lobby Ambassador users.
This vulnerability exists because parameters that are received by an API endpoint are not sufficiently validated. An attacker could exploit this vulnerability by authenticating as a Lobby Ambassador user and sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to create a new user with privilege level 1 access to the web-based management API. The attacker would then be able to access the device with these new credentials and privileges.

Summary
A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability exists because incorrect privileges are associated with the start maintenance command. An attacker could exploit this vulnerability by accessing the management CLI of the affected device as a low-privileged user and using the start maintenance command. A successful exploit could allow the attacker to put the device in maintenance mode, which shuts down interfaces, resulting in a denial of service (DoS) condition. In case of exploitation, a device administrator can connect to the CLI and use the stop maintenance command to restore operations.

Title
Cisco IOS Software and IOS XE Software Extensible Messaging Client Protocol Denial of Service Vulnerability
Summary
A vulnerability in the Extensible Messaging Client Protocol (XMCP), also referred to as the External Client protocol, of Cisco IOS Software and 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 handling of malformed XMCP packets. An attacker could exploit this vulnerability by sending a malformed XMCP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. The attacker does not need the XMCP client username to exploit this vulnerability.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information.

Title
Cisco IOS XE Software SNMP Denial of Service Vulnerability
Summary
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.
This vulnerability is due to improper error handling when parsing SNMP requests. This vulnerability affects all versions of SNMP — Versions 1, 2c, and 3. An attacker could exploit this vulnerability by sending a malformed SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly. The attacker must have the SNMPv1 or v2c read-only or read-write community string or valid SNMPv3 user credentials on the affected device.
