CVE-2024-31151 Information

Description

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 password string can be found at addresses 0x 803cdd0f and 0x803da3e6:

803cdd0f 41 72 69 65        ds         \AriesSerenaCairryNativitaMegan\r
         73 53 65 72 
         65 6e 61 43
         ...

It is referenced by the function at 0x800b78b0 and simplified in the pseudocode below:

if (is_equal = strcmp(password\AriesSerenaCairryNativitaMegan\)
    ret = 3;

Where 3 is the return value to user-level access (0 being fail and 1 being admin/backdoor).

While there’s no legitimate functionality to change this password once authenticated it is possible manually make a change by taking advantage of TALOS-2024-XXXXX using HTTP POST paramater \Pu\ (new user password) in place of \Pa\ (new admin password).
