CWE-122 06/05/2026
Cisco SG350 and SG350X Series Managed Switches SNMP Denial of Service Vunerability
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco 350 Series Managed Switches (SG350) and Cisco 350X Series Stackable Managed Switches (SG350X) firmware could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper error handling when parsing response data for a specific SNMP request. An attacker could exploit this vulnerability by sending a specific SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition.
This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMPv2c or earlier, the attacker must know a valid read-write or read-only SNMP community string for the affected system. To exploit this vulnerability through SNMPv3, the attacker must have valid SNMP user credentials for the affected system.

CWE-306 28/04/2026
Cisco Intersight Device Connector for Nutanix Prism Central Unauthenticated API Access
An improper access control vulnerability exists in the Cisco Intersight Device Connector for Nutanix Prism Central. The service exposes an API passthrough endpoint on TCP port 7373 that is accessible within the network scope of the deployment environment without authentication.
An unauthenticated attacker with network access can exploit this vulnerability by sending crafted requests to the exposed endpoint to enumerate cluster metadata, including virtual machine information and cluster configuration details. While the API primarily supports read-only operations, it also allows certain cluster maintenance workflows to be invoked.
Although this vulnerability does not allow persistent modification of system configurations or access to credentials or sensitive user data, successful exploitation may result in disruption of active workloads, leading to loss of service availability within the affected environment.

CWE-77 15/04/2026
Cisco Identity Services Engine Multiple Authenticated Remote Code Execution Vulnerability
A vulnerability in Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have at least Read Only Admin credentials.
This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain user-level access to the underlying operating system and then elevate privileges to root. In single-node ISE deployments, successful exploitation of these vulnerabilities could cause the affected ISE node to become unavailable, resulting in a denial of service (DoS) condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored.

CWE-295 15/04/2026
Cisco Webex SSO com Control Hub - Validação Imprópria de Certificado Permite Personificação de Usuários
Uma vulnerabilidade na integração de single sign-on (SSO) com o Control Hub nos Cisco Webex Services poderia permitir que um invasor remoto não autenticado se passasse por qualquer usuário do serviço.
Essa vulnerabilidade existia devido à validação imprópria de certificados. Antes de a vulnerabilidade ser tratada, um invasor poderia ter explorado essa falha conectando-se a um endpoint do serviço e fornecendo um token forjado. Uma exploração bem-sucedida poderia ter permitido ao invasor obter acesso não autorizado aos serviços legítimos do Cisco Webex.
