Cross-site request forgery (CSRF) vulnerability in the cpass functionality in an admin action in index.php in XCMS allows remote attackers to change arbitrary passwords via certain password_ and rpassword_ parameters, possibly related to timestamp values.

Multiple directory traversal vulnerabilities in index.php in XCMS 1.82 and earlier allow remote attackers to read arbitrary files via a .. (dot dot) in (1) the s parameter to the admin page or (2) the pg parameter to an arbitrary module, as demonstrated by reading a password hash in a .dtb file under dati/membri/ or by executing embedded PHP code in images under uploads/avatar/.

cpie.php in XCMS 1.83 and earlier sends a redirect to the web browser but does not exit, which allows remote attackers to conduct direct static code injection attacks and execute arbitrary code via the testo_0 parameter in a cpie admin action to index.php, which writes to dati/generali/footer.dtb (aka the XCMS footer).
