DNSTools could allow a remote attacker to bypass authentication by manipulating authentication variables
|dnstools-auth-bypass (8948)||Medium Risk|
DNSTools could allow a remote attacker to bypass authentication and modify DNS entries. A remote attacker could send a specially-crafted URL request to the dnstools.php script containing manipulated values for the user_logged_in and user_dnstools_administrator to gain administrator access to DNSTools. An attacker could use this vulnerability to prepare for future attacks against the affected network.
Upgrade to the latest version of DNSTools (2.0 beta 5 or later), available from the DNSTools Web site. See References.
