IBM Connections 5.0, 5.5, and 6.0 is vulnerable to possible host header injection attack that could cause navigation to the attacker's domain. IBM X-Force ID: 152456.

IBM Connections 5.0, 5.5, and 6.0 is vulnerable to an External Service Interaction attack, caused by improper validation of a request property. By submitting suitable payloads, an attacker could exploit this vulnerability to induce the Connections server to attack other systems. IBM X-Force ID: 148946.

IBM Connections 5.0, 5.5, and 6.0 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 135521.
