A vulnerability in the web framework of Cisco Emergency Responder could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface. The vulnerability is due to insufficient validation of some parameters that are passed to the web server of the affected software. An attacker could exploit this vulnerability by persuading a user to access a malicious link or by intercepting a user request for the affected web interface and injecting malicious code into that request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web-based management interface or access sensitive, browser-based information.

A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions with administrative privileges on an affected device. The vulnerability is due to improper handling of Lightweight Directory Access Protocol (LDAP) authentication responses from an external authentication server. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to gain administrative access to the web-based management interface of the affected device.

A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.

A vulnerability in the Administration Web Interface of Cisco Unified Contact Center Express (Unified CCX) could allow an authenticated, remote attacker to upload arbitrary files and execute commands on the underlying operating system. To exploit this vulnerability, an attacker needs valid Administrator credentials. The vulnerability is due to insufficient restrictions for the content uploaded to an affected system. An attacker could exploit this vulnerability by uploading arbitrary files containing operating system commands that will be executed by an affected system. A successful exploit could allow the attacker to execute arbitrary commands with the privileges of the web interface and then elevate their privileges to root.

A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause the CPU utilization to increase to 100 percent, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of email messages that contain large attachments. An attacker could exploit this vulnerability by sending a malicious email message through the targeted device. A successful exploit could allow the attacker to cause a permanent DoS condition due to high CPU utilization. This vulnerability may require manual intervention to recover the ESA.
