IBM Cognos Controller 10.4.1, 10.4.2, and 11.0.0 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic. IBM X-Force ID: 196640.

IBM Cognos Controller 10.4.1, 10.4.2, and 11.0.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 190837.

IBM Cognos Controller 10.4.0, 10.4.1, and 10.4.2 could be vulnerable to unauthorized modifications by using public fields in public classes. IBM X-Force ID: 190843.

IBM Cognos Controller 10.4.0, 10.4.1, and 10.4.2 could allow a remote attacker to bypass security restrictions, caused by improper validation of authentication cookies. IBM X-Force ID: 190847.

IBM Cognos Controller 10.4.0, 10.4.1, and 10.4.2 is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 190838.

IBM Cognos Controller 10.4.0, 10.4.1, and 10.4.2 is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 190839.

A low level user of IBM Cognos Controller 10.3.0, 10.3.1, 10.4.0, 10.4.1, and 10.4.2 who has Administration rights to the server where the application is installed, can escalate their privilege from Low level to Super Admin and gain access to Create/Update/Delete any level of user in Cognos Controller. IBM X-Force ID: 186625.

IBM Cognos Controller 10.3.0, 10.3.1, 10.4.0, and 10.4.1 could allow an authenticated user to obtain sensitive information due to easy to guess session identifier names. IBM X-Force ID: 162658.

IBM Cognos Controller stores sensitive information in URL parameters. This may lead to information disclosure if unauthorized parties have access to the URLs via server logs, referrer header or browser history. IBM X-Force ID: 162659.

IBM Cognos Controller 10.3.0, 10.3.1, 10.4.0, and 10.4.1 does not set the secure attribute on authorization tokens or session cookies. This could allow an attacker to obtain sensitive information using man in the middle techniques. IBM X-Force ID: 158876.
