Version Summary:IBM Lotus Connections contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks on a targeted system. Updates are available.
 
 
Description
A vulnerability in the Bookmarks component of IBM Lotus Connections could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks on a targeted system.

The vulnerability is due to insufficient sanitization of user-supplied input by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to follow a crafted URL. When processed, the URL could execute script in the user's web browser in the security context of the hosting website. An exploit could allow the attacker to access application cookies.

IBM has confirmed this vulnerability and released updated software.
 
Warning Indicators
The following IBM products are vulnerable:
  • IBM Lotus Connections - version 4.0
  • IBM Lotus Connections - 3.0.1.1 and earlier.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
 
Vendor Announcements
IBM has released a security alert at the following link: swg21634538
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary script code in the browser session under the security context of the affected website. Script execution could allow the attacker to access cached application cookies.
 
Technical Information
The vulnerability is due to insufficient validation of user-supplied input by the Bookmarks component when processing URL parameters.

An attacker may use this vulnerability to execute arbitrary script code in the browser in the context of the affected site. If successful, the attacker may steal cookie-based authentication credentials and launch further attacks.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Users should verify that unsolicited links are safe to follow.
