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.
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.
The following IBM products are vulnerable:
IBM Lotus Connections - version 4.0
IBM Lotus Connections - 220.127.116.11 and earlier.
