Cross-site request forgery (CSRF) vulnerability in the Profiles component in IBM Connections through 3.0.1.1 CR3 allows remote authenticated users to hijack the authentication of arbitrary users for requests that trigger follow actions.

Cross-site scripting (XSS) vulnerability in the Bookmarks component in IBM Lotus Connections before 4.0 CR3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The bookmarklet pop-up in the Bookmarks component in IBM Lotus Connections 2.5.x before 2.5.0.2 does not properly follow the "force SSL" setting, which might make it easier for remote attackers to obtain the cleartext of network communication by sniffing the network, or spoof arbitrary servers via a man-in-the-middle attack.

Open redirect vulnerability in the Mobile component in IBM Lotus Connections 2.5.x before 2.5.0.2 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors, related to "mobile edit actions," aka SPR ASRE83PPVH.

Multiple cross-site scripting (XSS) vulnerabilities in IBM Lotus Connections 2.5.x before 2.5.0.2 allow remote attackers to inject arbitrary web script or HTML via the (1) create or (2) edit form in the Communities component, the (3) verbiage field in the Bookmarks component, or (4) unspecified vectors related to the Mobile Blogs component.

The Top Updates implementation in the Homepage component in IBM Lotus Connections 2.5.x before 2.5.0.2, when "forced SSL" is enabled, uses http for links, which has unspecified impact and remote attack vectors.
