PACKAGE : imp
SUMMARY : Remote vulnerability affects the IMP webmail system
DATE : 2001-07-25 18:21:00
ID : CLA-2001:410
RELEVANT
RELEASES : 4.1, 4.2, 5.0, 5.1, 6.0, 7.0
- -------------------------------------------------------------------------
DESCRIPTION
"imp" is a webmail system that uses the "horde" framework.
The authors have released new versions of IMP and HORDE that address
security vulnerabilities disclosed by giancarlo pinerolo
([email protected]) and Nick Cleaton ([email protected]), as well
as one problem found during an internal audit.
1. A remote attacker could trick the server into fetching scripts
from another host and then execute them. This could be used to get
access to the server running this webmail system.
2. An attacker might also execute malicious javascript code in the
browser of an user who is reading an email sent by the attacker with
special "javascript:" encodings.
3. An attacker could make the server read a file called "prefs.lang"
and execute it as PHP code. The attacker would have to be able to
create that file first, which implies at least some sort of write
access, such as one provided by a shell account, or ftp upload.
SOLUTION
It is recommended that all users of the IMP webmail system (and
HORDE) upgrade their systems.
