A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to a missing authentication check in an API call. An attacker who can send a request to an affected system could cause all currently authenticated users to be logged off. Repeated exploitation could cause the inability to maintain a session in the web-based management portal.

A vulnerability in the web-based management interface of Cisco UCS Director could allow an unauthenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. 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 execute arbitrary script code in the context of the interface or allow the attacker to access sensitive, browser-based information.

A vulnerability in the web interface for specific feature sets of Cisco Integrated Management Controller (IMC) Supervisor and Cisco UCS Director could allow an authenticated, remote attacker to access sensitive information. The vulnerability is due to an authorization check that does not properly include the access level of the web interface user. An attacker who has valid application credentials could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to view sensitive information that belongs to other users. The attacker could then use this information to conduct additional reconnaissance attacks.

A vulnerability in the web-based management interface of Cisco UCS Director Software and Cisco Integrated Management Controller (IMC) Supervisor Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected system. The vulnerability is due to insufficient CSRF protection by the web-based management interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the affected interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions, via the user's web browser and with the user's privileges, on an affected system. Cisco Bug IDs: CSCvf71929.

Cisco UCS Director (formerly Cloupia) before 4.0.0.3 has a hardcoded password for the root account, which makes it easier for remote attackers to obtain administrative access via an SSH session to the CLI interface, aka Bug ID CSCui73930.
