Security Vulnerabilities - CVEs Published In May 2017
A vulnerability in the Telnet CLI command of Cisco NX-OS System Software 7.1 through 7.3 running on Cisco Nexus Series Switches could allow an authenticated, local attacker to perform a command injection attack. The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting crafted command arguments into the Telnet CLI command. An exploit could allow the attacker to read or write arbitrary files at the user's privilege level outside of the user's path. Cisco Bug IDs: CSCvb86771.

A vulnerability in the TCP throttling process for the GUI of the Cisco Identity Services Engine (ISE) 2.1(0.474) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device where the ISE GUI may fail to respond to new or established connection requests. The vulnerability is due to insufficient TCP rate limiting protection on the GUI. An attacker could exploit this vulnerability by sending the affected device a high rate of TCP connections to the GUI. An exploit could allow the attacker to cause the GUI to stop responding while the high rate of connections is in progress. Cisco Bug IDs: CSCvc81803.

A vulnerability in the web-based management interface of Cisco Unified Communications Manager 10.5 through 11.5 could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management 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 code in the context of the interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvc06608.

There is a debug-interface vulnerability on some Tenda routers (FH1202/F1202/F1200: versions before 1.2.0.20). After connecting locally to a router in a wired or wireless manner, one can bypass intended access restrictions by sending shell commands directly and reading their results, or by entering shell commands that change this router's username and password.

There is a stack-based buffer overflow on some Tenda routers (FH1202/F1202/F1200: versions before 1.2.0.20). Crafted POST requests to an unspecified URL result in DoS, interrupting the HTTP service (used to login to the web UI of a router) for 1 to 2 seconds.

An issue was discovered on Mimosa Client Radios before 2.2.3 and Mimosa Backhaul Radios before 2.2.3. By connecting to the Mosquitto broker on an access point and one of its clients, an attacker can gather enough information to craft a command that reboots the client remotely when sent to the client's Mosquitto broker, aka "unauthenticated remote command execution." This command can be re-sent endlessly to act as a DoS attack on the client.

A hard-coded credentials issue was discovered on Mimosa Client Radios before 2.2.3, Mimosa Backhaul Radios before 2.2.3, and Mimosa Access Points before 2.2.3. These devices run Mosquitto, a lightweight message broker, to send information between devices. By using the vendor's hard-coded credentials to connect to the broker on any device (whether it be an AP, Client, or Backhaul model), an attacker can view all the messages being sent between the devices. If an attacker connects to an AP, the AP will leak information about any clients connected to it, including the serial numbers, which can be used to remotely factory reset the clients via a page in their web interface.

An issue was discovered on Mimosa Client Radios before 2.2.3 and Mimosa Backhaul Radios before 2.2.3. In the device's web interface, after logging in, there is a page that allows you to ping other hosts from the device and view the results. The user is allowed to specify which host to ping, but this variable is not sanitized server-side, which allows an attacker to pass a specially crafted string to execute shell commands as the root user.

An information-leakage issue was discovered on Mimosa Client Radios before 2.2.3 and Mimosa Backhaul Radios before 2.2.3. There is a page in the web interface that will show you the device's serial number, regardless of whether or not you have logged in. This information-leakage issue is relevant because there is another page (accessible without any authentication) that allows you to remotely factory reset the device simply by entering the serial number.

An issue was discovered on Mimosa Client Radios before 2.2.4 and Mimosa Backhaul Radios before 2.2.4. On the backend of the device's web interface, there are some diagnostic tests available that are not displayed on the webpage; these are only accessible by crafting a POST request with a program like cURL. There is one test accessible via cURL that does not properly sanitize user input, allowing an attacker to execute shell commands as the root user.
