Security Bulletin: Vulnerability in Sametime Links (CVE-2013-0533)

Document information

IBM Sametime

STLinks/Toolkits

Software version:
8.0.2, 8.5, 8.5.1, 8.5.1.1, 8.5.1.2, 8.5.2, 8.5.2.1

Operating system(s):
Linux, Mac OS X, Windows

Reference #:
1633620

Modified date:
2013-04-22

Abstract

Sametime Links can be exploited to create a DOM-based XSS vulnerability. 
A fix is provided.

Content

CVE-ID: CVE-2013-0533

DESCRIPTION

The Lotus iNotes webmail interface includes a Sametime chat communication 
part. This interface suffers from a reflected, DOM-based XSS. As it is available 
on the same interface as the webmail system, this would allow attackers to 
execute arbitrary commands on the webmail interface for logged-in users and, 
for example, gain access to their emails. 

The issue can be fixed by updating the Sametime Links server with the fix 
provided here. 

CVSS: 

CVSS Base Score: 3.5 
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/82655 for the 
current score 
CVSS Environmental Score*: Undefined 
CVSS Vector: (AV:N/AC:M/AU:S/C:N/I:P/A:N) 

*The CVSS Environment Score is customer-environment specific and will ultimately 
impact the Overall CVSS Score. Customers can evaluate the impact of this 
vulnerability in their environments by accessing the links in the Reference 
section (below) of this Flash document.
