Stephen Craton » Chatness : Security Vulnerabilities, CVEs,

Stephen Craton (aka WiredPHP) Chatness 2.5.3 and earlier stores usernames and unencrypted passwords in (1) classes/vars.php and (2) classes/varstuff.php, and recommends 0666 or 0777 permissions for these files, which allows local users to gain privileges by reading the files, and allows remote attackers to obtain credentials via a direct request for admin/options.php.

Direct static code injection vulnerability in admin/save.php in Stephen Craton (aka WiredPHP) Chatness 2.5.3 and earlier allows remote authenticated administrators to inject PHP code into .html files via the html parameter, as demonstrated by head.html and foot.html, which are included and executed upon a direct request for index.php. NOTE: a separate vulnerability could be leveraged to make this issue exploitable by remote unauthenticated attackers.

admin/options.php in Stephen Craton (aka WiredPHP) Chatness 2.5.3 and earlier does not check for administrative credentials, which allows remote attackers to read and modify the classes/vars.php and classes/varstuff.php configuration files via direct requests.
