Directory traversal vulnerability in Nodez 4.6.1.1 and earlier allows remote attackers to read or include arbitrary PHP files via a .. (dot dot) in the op parameter, as demonstrated by inserting malicious Email parameters into list.gtdat, then accessing list.gtdat using the op parameter.

Cross-site scripting (XSS) vulnerability in Nodez 4.6.1.1 allows remote attackers to inject arbitrary web script or HTML via the op parameter. NOTE: it is possible that this issue is resultant from the directory traversal vulnerability.

Nodez 4.6.1.1 and earlier stores sensitive data in the list.gtdat file under the web document root with insufficient access control, which allows remote attackers to obtain usernames and password hashes by directly accessing list.gtdat.
