Vulnerabilities in this advisory
- CVE-2023-27407 — CVE-2023-27407 · CWE-77
The web based management of affected device does not properly validate user input, making it susceptible to command injection. This could allow an authenticated remote attacker to access the underlying operating system as the root user.
- CVE-2023-27408 — CVE-2023-27408 · CWE-378
The `i2c` mutex file is created with the permissions bits of `-rw-rw-rw-`. This file is used as a mutex for multiple applications interacting with i2c. This could allow an authenticated attacker with access to the SSH interface on the affected device to interfere with the integrity of the mutex and the data it protects.
- CVE-2023-27409 — CVE-2023-27409 · CWE-22
A path traversal vulnerability was found in the `deviceinfo` binary via the `mac` parameter. This could allow an authenticated attacker with access to the SSH interface on the affected device to read the contents of any file named `address`.
- CVE-2023-27410 — CVE-2023-27410 · CWE-122
A heap-based buffer overflow vulnerability was found in the `edgebox_web_app` binary. The binary will crash if supplied with a backup password longer than 255 characters. This could allow an authenticated privileged attacker to cause a denial of service.
