Description:
ShineShadow has reported two weaknesses in IceWarp Web Mail, which can be exploited by malicious users to gain knowledge of certain system information or sensitive information.

1) An error message containing the absolute installation path is returned, when a malicious user accesses "calendar_d.html", "calendar_m.html", "calendar_w.html", and "calendar_y.html" directly with a valid session ID in the "id" parameter.

The weakness has been reported in versions 5.3.2 and 5.3.0. Other versions may also be affected.

2) User credentials are stored obfuscated and with weak encryption in the files "users.cfg", "settings.cfg", "user.dat", and "users.dat" and are readable by any local user on the system.

The weakness has been reported in versions 5.3.0 and 5.3.2. Other versions may also be affected.

NOTE: Some other issues, which don't affect version 5.3.2, have also been reported in version 5.3.0.

Solution:
Update to version 5.3.2 (included in Merak Mail Server 7.6.4r) and grant only trusted users access to affected systems and the web mail functionality.
