Cisco: >> Email Security Appliance Security Vulnerabilities
Vulnerability in the CLI of Cisco Secure Email Gateway could allow an authenticated, remote attacker to execute arbitrary commands.
These vulnerability is due to improper input validation in the CLI. 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.

A vulnerability in the Web UI and administrative CLI of the Cisco Secure Email Gateway (ESA) and Cisco Secure Email and Web Manager (SMA) could allow an authenticated remote attacker and or authenticated local attacker to escalate their privilege level and gain root access. The attacker has to have a valid user credential with at least a [[privilege of operator - validate actual name]].
The vulnerability is due to the processing of a specially crafted SNMP configuration file. An attacker could exploit this vulnerability by authenticating to the targeted device and uploading a specially crafted SNMP configuration file that when uploaded could allow for the execution of commands as root. An exploit could allow the attacker to gain root access on the device.

A vulnerability in Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper handling of certain TLS connections that are processed by an affected device. An attacker could exploit this vulnerability by establishing a large number of concurrent TLS connections to an affected device. A successful exploit could allow the attacker to cause the device to drop new TLS email messages that come from the associated email servers. Exploitation of this vulnerability does not cause the affected device to unexpectedly reload. The device will recover autonomously within a few hours of when the attack is halted or mitigated.

A vulnerability in Cisco Email Security Appliance (ESA) and Cisco Secure Email and Web Manager could allow an unauthenticated, remote attacker to conduct an HTTP response splitting attack.
This vulnerability is due to the failure of the application or its environment to properly sanitize input values. An attacker could exploit this vulnerability by injecting malicious HTTP headers, controlling the response body, or splitting the response into multiple responses.

A vulnerability in the web management interface of Cisco Secure Email and Web Manager, formerly Cisco Security Management Appliance (SMA), and Cisco Email Security Appliance (ESA) could allow an authenticated, remote attacker to retrieve sensitive information from a Lightweight Directory Access Protocol (LDAP) external authentication server connected to an affected device. This vulnerability is due to a lack of proper input sanitization while querying the external authentication server. An attacker could exploit this vulnerability by sending a crafted query through an external authentication web page. A successful exploit could allow the attacker to gain access to sensitive information, including user credentials from the external authentication server. To exploit this vulnerability, an attacker would need valid operator-level (or higher) credentials.

A vulnerability in the external authentication functionality of Cisco Secure Email and Web Manager, formerly known as Cisco Security Management Appliance (SMA), and Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass authentication and log in to the web management interface of an affected device. This vulnerability is due to improper authentication checks when an affected device uses Lightweight Directory Access Protocol (LDAP) for external authentication. An attacker could exploit this vulnerability by entering a specific input on the login page of the affected device. A successful exploit could allow the attacker to gain unauthorized access to the web-based management interface of the affected device.

A vulnerability in the TCP/IP stack of Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Secure Email and Web Manager, formerly Security Management Appliance, could allow an unauthenticated, remote attacker to crash the Simple Network Management Protocol (SNMP) service, resulting in a denial of service (DoS) condition. This vulnerability is due to an open port listener on TCP port 199. An attacker could exploit this vulnerability by connecting to TCP port 199. A successful exploit could allow the attacker to crash the SNMP service, resulting in a DoS condition.

A vulnerability in the Cisco Advanced Malware Protection (AMP) for Endpoints integration of Cisco AsyncOS for Cisco Email Security Appliance (ESA) and Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to intercept traffic between an affected device and the AMP servers. This vulnerability is due to improper certificate validation when an affected device establishes TLS connections. A man-in-the-middle attacker could exploit this vulnerability by sending a crafted TLS packet to an affected device. A successful exploit could allow the attacker to spoof a trusted host and then extract sensitive information or alter certain API requests.

A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Content Security Management Appliance (SMA), Cisco Email Security Appliance (ESA), and Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability exists because confidential information is included in HTTP requests that are exchanged between the user and the device. An attacker could exploit this vulnerability by looking at the raw HTTP requests that are sent to the interface. A successful exploit could allow the attacker to obtain some of the passwords that are configured throughout the interface.

A vulnerability in the authentication for the general purpose APIs implementation of Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA), and Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to access general system information and certain configuration information from an affected device. The vulnerability exists because a secure authentication token is not required when authenticating to the general purpose API. An attacker could exploit this vulnerability by sending a crafted request for information to the general purpose API on an affected device. A successful exploit could allow the attacker to obtain system and configuration information from the affected device, resulting in an unauthorized information disclosure.
