HCL Connections v5.5, v6.0, and v6.5 contains an open redirect vulnerability which could be exploited by an attacker to conduct phishing attacks.

"HCL Connections is vulnerable to possible information leakage and could disclose sensitive information via stack trace to a local user."

HCL Connections v5.5, v6.0, and v6.5 are vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

The HCL Connections 5.5 help system is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

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 could allow an authenticated user to obtain sensitive information from invalid request error messages. IBM X-Force ID: 153315.

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.

IBM Connections 4.0, 4.5, 5.0, 5.5, and 6.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 134004.

IBM Connections 5.5 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 129020.
