The Meatmeet Pro was found to be shipped with hardcoded Wi-Fi credentials in the firmware, for the test network it was developed on. If an attacker retrieved this, and found the physical location of the Wi-Fi network, they could gain unauthorized access to the Wi-Fi network of the vendor. Additionally, if an attacker were located in close physical proximity to the device when it was first set up, they may be able to force the device to auto-connect to an attacker-controlled access point by setting the SSID and password to the same as which was found in the firmware file.

Trango Apex <= 2.1.1, ApexLynx < 2.0, ApexOrion < 2.0, ApexPlus <= 3.2.0, Giga <= 2.6.1, GigaLynx < 2.0, GigaOrion < 2.0, GigaPlus <= 3.2.3, GigaPro <= 1.4.1, StrataLink < 3.0, and StrataPro devices have a built-in, hidden root account, with a default password that was once stored in cleartext within a software update package on a Trango FTP server. This account is accessible via SSH and/or TELNET, and grants access to the underlying embedded UNIX OS on the device, allowing full control over it.

FreePBX is an open source IP PBX. From 15.0.42 to before 16.0.45 and 17.0.7, unauthenticated users may be able to access the User Control Panel (UCP) using hard-coded initial template credentials if these were not immediately changed by the Administrator who enabled UCP. Authenticated access to ACP is required for the initial setup of UCP generic templates, but after that, without further steps by the admin, unauthenticated users may be able to gain access. This vulnerability is fixed in 16.0.45 and 17.0.7.

MeterSphere is a one-stop open source continuous testing platform, covering functions such as test tracking, interface testing, UI testing and performance testing.

Trango ApexLynx 2.0, ApexOrion 2.0, GigaLynx 2.0, GigaOrion 2.0, and StrataLink 3.0 devices have a built-in, hidden root account, with a default password for which the MD5 hash value is public (but the cleartext value is perhaps not yet public). This account is accessible via SSH and/or TELNET, and grants access to the underlying embedded UNIX OS on the device, allowing full control over it.

In SapphireIMS 5.0, it is possible to use the hardcoded credential in clients (username: sapphire, password: ims) and gain access to the portal. Once the access is available, the attacker can inject malicious OS commands on “ping”, “traceroute” and “snmp” functions and execute code on the server. We also observed the same is true if the JSESSIONID is completely removed.
