Security Impact Rating: Critical CVE: CVE-2025-20188
  • Cisco Identity Services Engine on Cloud Platforms Static Credential Vulnerability
    A vulnerability in Amazon Web Services (AWS), Microsoft Azure, and Oracle Cloud Infrastructure (OCI) cloud deployments of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to access sensitive data, execute limited administrative operations, modify system configurations, or disrupt services within the impacted systems. This vulnerability exists because credentials are improperly generated when Cisco ISE is being deployed on cloud platforms, resulting in different Cisco ISE deployments sharing the same credentials. These credentials are shared across multiple Cisco ISE deployments as long as the software release and cloud platform are the same. An attacker could exploit this vulnerability by extracting the user credentials from Cisco ISE that is deployed in the cloud and then using them to access Cisco ISE that is deployed in other cloud environments through unsecured ports. A successful exploit could allow the attacker to access sensitive data, execute limited administrative operations, modify system configurations, or disrupt services within the impacted systems. Note: If the Primary Administration node is deployed in the cloud, then Cisco ISE is affected by this vulnerability. If the Primary Administration node is on-premises, then it is not affected. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link:https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-aws-static-cred-FPMjUcm7 Security Impact Rating: Critical CVE: CVE-2025-20286
  • Cisco Customer Collaboration Platform Information Disclosure Vulnerability
    A vulnerability in the web-based chat interface of Cisco Customer Collaboration Platform (CCP), formerly Cisco SocialMiner, could allow an unauthenticated, remote attacker to persuade users to disclose sensitive data. This vulnerability is due to improper sanitization of HTTP requests that are sent to the web-based chat interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to the chat interface of a targeted user on a vulnerable server. A successful exploit could allow the attacker to redirect chat traffic to a server that is under their control, resulting in sensitive information being redirected to the attacker. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
