A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script or HTML code in the context of the interface, which could allow the attacker to gain access to sensitive, browser-based information.

A vulnerability in the web interface of Cisco Managed Services Accelerator (MSX) could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user’s HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. A successful exploit could allow the attacker to redirect a user to a malicious web page. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.

A vulnerability in the implementation of the Lua interpreter integrated in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying Linux operating system of an affected device. The vulnerability is due to insufficient restrictions on the allowed Lua function calls within the context of user-supplied Lua scripts. A successful exploit could allow the attacker to trigger a heap overflow condition and execute arbitrary code with root privileges on the underlying Linux operating system of an affected device.

A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to access sensitive device information. The vulnerability exists because the software lacks proper authentication controls to information accessible from the web UI. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web UI of an affected device. A successful exploit could allow the attacker to access sensitive device information, which includes configuration files.

A vulnerability in the automatic update process of Cisco Umbrella Roaming Client for Windows could allow an authenticated, local attacker to install arbitrary, unapproved applications on a targeted device. The vulnerability is due to insufficient verification of the Windows Installer. An attacker could exploit this vulnerability by placing a file in a specific location in the Windows file system. A successful exploit could allow the attacker to bypass configured policy and install unapproved applications.
