NetComm NF20MESH < R6B032 Hardcoded AES Key Authentication Bypass

NetComm NF20MESH routers running firmware R6B031 and earlier contain an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by exploiting a hardcoded AES-256 key used to encrypt session cookies for the web management interface. Attackers can forge a valid encrypted session cookie using the shared hardcoded key and bypass authentication checks to obtain full administrative control of the management interface while any legitimate administrator session is active.

NetComm NF20MESH < R6B032 Authenticated RCE via OS Command Injection

NetComm NF20MESH routers running firmware R6B031 and earlier contain an authenticated remote code execution vulnerability that allows authenticated attackers to execute arbitrary commands as root by injecting shell metacharacters into the username JSON parameter processed by the dalStorage_addUserAccount function. Attackers can exploit the unsafe concatenation of user-supplied input into a shell command string passed to rut_doSystemAction without sanitization to achieve full root-level command execution on the underlying operating system.

Authenticated bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows unauthenticated user to get access to content.

Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content. In order to serve static content, the application performs a check for the existence of specific characters in the URL (.css, .png etc). If it exists, it performs a "fake login" to give the request an active session to load the file and not redirect to the login page.

Stack based overflow on Netcomm router models NF20MESH, NF20, and NL1902

On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter. By providing a specific number of bytes, the instruction pointer is able to be overwritten on the stack and crashes the application at a known location.

ping.cgi in NetCommWireless HSPA 3G10WVE wireless routers with firmware before 3G10WVE-L101-S306ETS-C01_R05 allows remote attackers to bypass intended access restrictions via a direct request. NOTE: this issue can be combined with CVE-2015-6024 to execute arbitrary commands.

ping.cgi in NetCommWireless HSPA 3G10WVE wireless routers with firmware before 3G10WVE-L101-S306ETS-C01_R05 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the DIA_IPADDRESS parameter.

Cross-site scripting (XSS) vulnerability in wlsecurity.html on NetCommWireless NB604N routers with firmware before GAN5.CZ56T-B-NC.AU-R4B030.EN allows remote attackers to inject arbitrary web script or HTML via the wlWpaPsk parameter.

NetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior. The directory of the device is listed openly without authentication.

NetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior. The device is vulnerable to several cross-site scripting attacks, allowing a remote attacker to run arbitrary code on the device.

NetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior. A cross-site request forgery condition can occur, allowing an attacker to change passwords of the device remotely.

NetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior. The device allows access to configuration files and profiles without authenticating the user.
