Secunia Advisory SA24633

Where:

From remote

Impact:

Cross Site Scripting, DoS, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Some vulnerabilities have been reported in IBM Lotus Domino and Lotus Domino Web Access, which can be exploited by malicious people to conduct script insertion attacks, cause a DoS (Denial of Service), and potentially compromise a vulnerable system.

1) A boundary error within the IMAP service (nimap.exe) during CRAM-MD5 authentication can be exploited to cause a buffer overflow by passing an overly long username (more than 256 bytes).

Successful exploitation crashes the service and may allow execution of arbitrary code.

2) An error in the LDAP service when handling certain requests can be exploited to cause a heap-based buffer overflow via a specially crafted request containing a string longer than 65535 bytes.

Successful exploitation crashes the service and may allow execution of arbitrary code.

3) Some input in e-mail messages are not properly sanitised by Lotus Domino Web Access before being displayed. These can be exploited to insert arbitrary HTML and script code, which are executed in a user's browser session in context of an affected site when a malicious message is viewed.


Solution:
Update to version 6.5.5 Fix Pack 3 (FP3), 6.5.6, or 7.0.2 Fix Pack 1.
