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.
TUCoPS is optimized to look best in Firefox® on a widescreen monitor (1440x900 or better).
