SA-CONTRIB-2013-067 - BOTCHA - Information Disclosure (potential Privilege Escalation)

BOTCHA is a highly configurable non-CAPTCHA spam protection framework. The module includes a debug mode which logs the content of submitted forms including passwords and other sensitive information. An attacker who gains access to the log (i.e. dblog or syslog depending on configuration) could get access to usernames and passwords or other sensitive information. The vulnerability is mitigated by the fact that the debugging level must be set to level 5 or 6 (a high level) and the attacker must gain access to the logs (i.e. “access site reports” permission or access to syslog).

If you debug level 5 or 6 enabled on a production site, you should consider expiring passwords and instruct users to change their passwords.
