CVE-2017-1748 [Medium] | Spoofing in Connections

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.
