A vulnerability in role-based access control of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow a read-only authenticated, remote attacker to disable user accounts on an affected system. The vulnerability is due to incorrect allocation of the enable/disable action button under the role-based access control code on an affected system. An attacker could exploit this vulnerability by authenticating as a read-only user and then updating the roles of other users to disable them. A successful exploit could allow the attacker to disable users, including administrative users.

A vulnerability in the web-based management interface for Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to impact the integrity of an affected system by executing arbitrary SQL queries. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted input that includes SQL statements to an affected system. A successful exploit could allow the attacker to modify entries in some database tables, affecting the integrity of the data.

A Read-Only User Effect Change vulnerability in the Policy Builder interface of Cisco Policy Suite could allow an authenticated, remote attacker to make policy changes in the Policy Builder interface. The vulnerability is due to insufficient authorization controls. An attacker could exploit this vulnerability by accessing the Policy Builder interface and modifying an HTTP request. A successful exploit could allow the attacker to make changes to existing policies. Cisco Bug IDs: CSCvi35007.

Cisco TelePresence Video Communication Server (VCS) Expressway X8.6 allows remote authenticated users to bypass intended read-only restrictions and upload Tandberg Linux Package (TLP) files by visiting an administrative page, aka Bug ID CSCuw55651.
