COMMAND IMHO webmail allows reading other users mail SYSTEMS AFFECTED IMHO 0.97.x and Roxen 1.3.122 PROBLEM SecurityBugware was informed that : If on an IMHO based system, you : - Login with an valid user/passwd, - Logout - Goto URL : (((webmail_URL)))/(old_error,plain)/mail/error?error=1 [if IMHO module is mounted un /mail/] You will see a error page with a referer, just copy and paste it to your browser and you\'ll get the inbox contents. This works if session has not expired, and browser wasn\'t closed. SOLUTION Update ====== To fix the issue add the following line to Roxen configuration file and reload Roxen : Global Variables -> Show the internals : No Note that although CAMAS was initially an IMHO fork, it is unafected by the bug.
