Mimosa : Security Vulnerabilities, CVEs,

The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 allows authenticated command injection in the Throughput, WANStats, PhyStats, and QosStats API classes. An attacker with access to a web console account may execute operating system commands on affected devices by sending crafted POST requests to the affected endpoints (/core/api/calls/Throughput.php, /core/api/calls/WANStats.php, /core/api/calls/PhyStats.php, /core/api/calls/QosStats.php). This results in the complete takeover of the vulnerable device. This vulnerability does not occur in the older 1.5.x firmware versions.

The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 is vulnerable to stored XSS in the set_banner() function of /var/www/core/controller/index.php. An unauthenticated attacker may set the contents of the /mnt/jffs2/banner.txt file, stored on the device's filesystem, to contain arbitrary JavaScript. The file contents are then used as part of a welcome/banner message presented to unauthenticated users who visit the login page for the web console. This vulnerability does not occur in the older 1.5.x firmware versions.

An issue was discovered on Mimosa Client Radios before 2.2.3. In the device's web interface, there is a page that allows an attacker to use an unsanitized GET parameter to download files from the device as the root user. The attacker can download any file from the device's filesystem. This can be used to view unsalted, MD5-hashed administrator passwords, which can then be cracked, giving the attacker full admin access to the device's web interface. This vulnerability can also be used to view the plaintext pre-shared key (PSK) for encrypted wireless connections, or to view the device's serial number (which allows an attacker to factory reset the device).

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.

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 2.2.3 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.

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. 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.
