Qualcomm WorldMail IMAP Server String Literal Processing Overflow
------------------------------------------------------------------------
SUMMARY
<http://www.eudora.com/worldmail/>; Qualcomm WorldMail is "an email and
messaging server designed for use in small to large enterprises that
supports IMAP, POP3, SMTP, and web mail features".
Remote exploitation of a buffer overflow vulnerability in Qualcomm
WorldMail IMAP Server allows unauthenticated attackers to execute
arbitrary code.
DETAILS
Vulnerable Systems:
* Qualcomm Worldmail server version 3.0
Successful exploitation of this vulnerability allows attackers to execute
arbitrary code with SYSTEM privileges. This leads to a total compromise of
the mail server.
In order to trigger this overflow, an attacker only needs to send a long
string ending with a '}' character. This will result in a stack overflow
and the attacker may use an SEH overwrite or a standard EBP or EIP
overwrite in order to gain control of the process trivially.
This is a pre-authentication vulnerability. To exploit this vulnerability
an attacker would need to be able connect to the e-mail server and the
IMAP module would have to be enabled (default). Only one command is
required to trigger this vulnerability.
Workaround:
There is no workaround currently available except for disabling IMAP
services.
