Cisco Elastic Services Controller Service Portal Authentication Bypass Vulnerability

A vulnerability in the authentication functionality of the web-based service portal of Cisco Elastic Services Controller Software could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions with administrator privileges on an affected system.

The vulnerability is due to improper security restrictions that are imposed by the web-based service portal of the affected software. An attacker could exploit this vulnerability by submitting an empty password value to an affected portal when prompted to enter an administrative password for the portal. A successful exploit could allow the attacker to bypass authentication and gain administrator privileges for the web-based service portal of the affected software.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Identity Services Engine Privilege Escalation Vulnerability

A vulnerability in the administrative web interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to gain additional privileges on an affected device.

The vulnerability is due to improper controls on certain pages in the web interface. An attacker could exploit this vulnerability by authenticating to the device with an administrator account and sending a crafted HTTP request. A successful exploit could allow the attacker to create additional Admin accounts with different user roles. An attacker could then use these accounts to perform actions within their scope. The attacker would need valid Admin credentials for the device. This vulnerability cannot be exploited to add a Super Admin account.

Cisco Small Business Switches Privileged Access Vulnerability

A vulnerability in the Cisco Small Business Switches software could allow an unauthenticated, remote attacker to bypass the user authentication mechanism of an affected device.

The vulnerability exists because under specific circumstances, the affected software enables a privileged user account without notifying administrators of the system. An attacker could exploit this vulnerability by using this account to log in to an affected device and execute commands with full admin rights.

Cisco has not released software updates that address this vulnerability. This advisory will be updated with fixed software information once fixed software becomes available. There is a workaround to address this vulnerability.

Cisco Webex Meetings Desktop App Update Service Command Injection Vulnerability

A vulnerability in the update service of Cisco Webex Meetings Desktop App for Windows could allow an authenticated, local attacker to execute arbitrary commands as a privileged user.

The vulnerability is due to insufficient validation of user-supplied parameters. An attacker could exploit this vulnerability by invoking the update service command with a crafted argument. An exploit could allow the attacker to run arbitrary commands with SYSTEM user privileges.

While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access, administrators should be aware that in Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
