CVE-2019-15654
Comba AP2600-I devices through A02,0202N00PD2 are prone to password disclosure via a simple crafted /09/business/upgrade/upcfgAction.php?download=true request to the web management server. The request doesn’t require any authentication and will lead to saving the DBconfig.cfg file. At the end of the file, the login information is stored in cleartext.
