IBM Cúram Social Program management contains a number of servlets which do not adequately protect against CSRF. This could potentially allow an attacker to affect the integrity of data managed by these servlets.
DESCRIPTION: IBM Curam Social Program Management is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.

Workarounds and Mitigations
There are a number of options to mitigate this issue. The general premise behind these mitigations is that generally these servlets are more useful in development and test environments than in the live system
This issue can be worked around by NOT deploying the following servlets to your live system:
This issue can be worked around by modifying user roles so that these servlets cannot be accessed by any users in the production environment. This can be achieved using standard Curam user interface for security roles.
