An issue was discovered in Luvion Grand Elite 3 Connect through 2020-02-25. Authentication to the device is based on a username and password. The root credentials are the same across all devices of this model.

An issue was discovered in the rand_core crate before 0.6.2 for Rust. Because read_u32_into and read_u64_into mishandle certain buffer-length checks, a random number generator may be seeded with too little data.

An issue was discovered in the autorand crate before 0.2.3 for Rust. Because of impl Random on arrays, uninitialized memory can be dropped when a panic occurs, leading to memory corruption.

An issue was discovered in the nanorand crate before 0.5.1 for Rust. It caused any random number generator (even ChaCha) to return all zeroes because integer truncation was mishandled.

An issue was discovered in the rand_core crate before 0.4.2 for Rust. Casting of byte slices to integer slices mishandles alignment constraints.

Incorrect input sanitation in text-oriented user interfaces (telnet, ssh) in Swisscom Centro Grande before 6.16.12 allows remote authenticated users to execute arbitrary commands via command injection.

Missing hostname validation in Swisscom Centro Grande before 6.16.12 allows a remote attacker to inject its local IP address as a domain entry in the DNS service of the router via crafted hostnames in DHCP requests, causing XSS.

Missing output sanitation in Swisscom Centro Grande Centro Grande before 6.16.12, Centro Business 1.0 (ADB) before 7.10.18, and Centro Business 2.0 before 8.02.04 allows a remote attacker to perform DNS spoofing against the web interface via crafted hostnames in DHCP requests.

GRANDIT Ver.1.6, Ver.2.0, Ver.2.1, Ver.2.2, Ver.2.3, and Ver.3.0 do not properly manage sessions, which allows remote attackers to impersonate an arbitrary user and then alter or disclose the information via unspecified vectors.

Grand MA 300 allows a brute-force attack on the PIN.
