A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to access sensitive information. This vulnerability is due to missing authorization for certain resources in the web-based management interface together with insufficient entropy in these resource names. An attacker could exploit this vulnerability by sending a series of HTTPS requests to an affected device to enumerate resources on the device. A successful exploit could allow the attacker to retrieve sensitive information from the device.

A vulnerability in the module import function of the administrative interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to view sensitive information. This vulnerability is due to insufficient validation of the XML syntax when importing a module. An attacker could exploit this vulnerability by supplying a specially crafted XML file to the function. A successful exploit could allow the attacker to read sensitive data that would normally not be revealed.

A vulnerability in the authentication and authorization flows for VPN connections in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to establish a connection as a different user. This vulnerability is due to a flaw in the authorization verifications during the VPN authentication flow. An attacker could exploit this vulnerability by sending a crafted packet during a VPN authentication. The attacker must have valid credentials to establish a VPN connection. A successful exploit could allow the attacker to establish a VPN connection with access privileges from a different user.

A vulnerability in the SSL/TLS client of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper memory management when a device initiates SSL/TLS connections. An attacker could exploit this vulnerability by ensuring that the device will connect to an SSL/TLS server that is using specific encryption parameters. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.

A vulnerability in the TLS handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to gain access to sensitive information. This vulnerability is due to improper implementation of countermeasures against a Bleichenbacher attack on a device that uses SSL decryption policies. An attacker could exploit this vulnerability by sending crafted TLS messages to an affected device, which would act as an oracle and allow the attacker to carry out a chosen-ciphertext attack. A successful exploit could allow the attacker to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions to the affected device.

A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software and Cisco FXOS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as root. This vulnerability is due to improper input validation for specific CLI commands. An attacker could exploit this vulnerability by injecting operating system commands into a legitimate command. A successful exploit could allow the attacker to escape the restricted command prompt and execute arbitrary commands on the underlying operating system. To successfully exploit this vulnerability, an attacker would need valid Administrator credentials.

Marcin 'Icewall’ Noga of Cisco Talos discovered these vulnerabilities. Cisco Talos recently discovered a class attribute double-free vulnerability in Microsoft Office. Microsoft Office is a suite of tools used for productivity in both a corporate environment as well as by end-users. It offers a range of tools that

Cisco Secure Email Gateways, formerly known as Cisco Ironport Email Security Appliances, that are configured to detect malicious email attachments, can easily be circumvented. A remote attacker can leverage error tolerance and different MIME decoding capabilities of email clients, compared with the gateway, to evade detection of malicious payloads by anti-virus components on the gateway. This exploit was successfully tested with a zip file containing the Eicar test virus and Cisco Secure Email Gateways with AsyncOS 14.2.0-620, 14.0.0-698, and others. An affected Email Client was Mozilla Thunderbird 91.11.0 (64-bit).
