What is CVE-2024-28875? In plain terms.
It can be attacked from anywhere on the internet without logging in, and nobody has to click anything. If it works, the attacker can read data, change data and take it offline.
A security flaw involving hard-coded credentials in LevelOne WBR-6012's web services allows attackers to gain unauthorized access during the first 30 seconds post-boot. Other vulnerabilities can force a reboot, circumventing the initial time restriction for exploitation.The backdoor string can be found at address 0x80100910
80100910 40 6d 21 74 ds "@m!t2K1" 32 4b 31 00
It is referenced by the function located at 0x800b78b0 and is used as shown in the pseudocode below:
if ((SECOND_FROM_BOOT_TIME < 300) && (is_equal = strcmp(password,"@m!t2K1")) { return 1;}
Where 1 is the return value to admin-level access (0 being fail and 3 being user).
