ELSEIF CMS Beta 0.6 does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code by uploading a .php file via externe/swfupload/upload.php. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in ELSEIF CMS.

Multiple cross-site scripting (XSS) vulnerabilities in ELSEIF CMS Beta 0.6 allow remote attackers to inject arbitrary web script or HTML via the (1) repertimage parameter to utilisateurs/vousetesbannis.php, the (2) elseifvotetxtresultatduvote parameter to utilisateurs/votesresultats.php, and the (3) elseifforumtxtmenugeneraleduforum parameter to moduleajouter/depot/adminforum.php.

Multiple PHP remote file inclusion vulnerabilities in ELSEIF CMS Beta 0.6 allow remote attackers to execute arbitrary PHP code via a URL in the (1) contenus parameter to (a) contenus.php; the (2) tpelseifportalrepertoire parameter to (b) votes.php, (c) espaceperso.php, (d) enregistrement.php, (e) commentaire.php, and (f) coeurusr.php in utilisateurs/, and (g) articles/fonctions.php and (h) depot/fonctions.php in moduleajouter/; the (3) corpsdesign parameter to (i) articles/usrarticles.php and (j) depot/usrdepot.php in moduleajouter/; and possibly other files.

ELSEIF CMS Beta 0.6 allows remote attackers to obtain sensitive information (full path) via unspecified vectors to utilisateurs/votesresultats.php.
