An issue was discovered on Swisscom Internet Box 2, Internet Box Standard, Internet Box Plus prior to 10.04.38, Internet Box 3 prior to 11.01.20, and Internet Box light prior to 08.06.06. Given the (user-configurable) credentials for the local Web interface or physical access to a device's plus or reset button, an attacker can create a user with elevated privileges on the Sysbus-API. This can then be used to modify local or remote SSH access, thus allowing a login session as the superuser.

Dell Client Consumer and Commercial platforms include an improper authorization vulnerability in the Dell Manageability interface for which an unauthorized actor, with local system access with OS administrator privileges, could bypass the BIOS Administrator authentication to restore BIOS Setup configuration to default values.

A command injection vulnerability has been discovered in the bootstrap stage of Bitdefender BOX 2, versions 2.1.47.42 and 2.1.53.45. The API method `/api/download_image` unsafely handles the production firmware URL supplied by remote servers, leading to arbitrary execution of system commands. In order to exploit the condition, an unauthenticated attacker should impersonate a infrastructure server to trigger this vulnerability.

A OS Command Injection vulnerability in the bootstrap stage of Bitdefender BOX 2 allows the manipulation of the `get_image_url()` function in special circumstances to inject a system command.

An exploitable command execution vulnerability exists in the recovery partition of Bitdefender BOX 2, version 2.0.1.91. The API method `/api/update_setup` does not perform firmware signature checks atomically, leading to an exploitable race condition (TOCTTOU) that allows arbitrary execution of system commands. This issue affects: Bitdefender Bitdefender BOX 2 versions prior to 2.1.47.36.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

Select Dell Client Commercial and Consumer platforms contain an Improper Access Vulnerability. An unauthenticated attacker with physical access to the system could potentially bypass intended Secure Boot restrictions to run unsigned and untrusted code on expansion cards installed in the system during platform boot. Refer to https://www.dell.com/support/article/us/en/04/sln317683/dsa-2019-043-dell-client-improper-access-control-vulnerability?lang=en for versions affected by this vulnerability.

A stack-based buffer overflow in the LAN UPnP service running on UDP port 1900 of Swisscom Internet-Box (2, Standard, and Plus) prior to v09.04.00 and Internet-Box light prior to v08.05.02 allows remote code execution. No authentication is required to exploit this vulnerability. Sending a simple UDP packet to port 1900 allows an attacker to execute code on a remote device. However, this is only possible if the attacker is inside the LAN. Because of ASLR, the success rate is not 100% and leads instead to a DoS of the UPnP service. The remaining functionality of the Internet Box is not affected. A reboot of the Internet Box is necessary to attempt the exploit again.

CompuLab Intense PC and MintBox 2 devices with BIOS before 2017-05-21 do not use the CloseMnf protection mechanism for write protection of flash memory regions, which allows local users to install a firmware rootkit by leveraging administrative privileges.
