Advisory Details:

(1) Vendor URL:
http://www.exlibrisgroup.org/display/CrossProductCC/PDS+OpenSSO+Integration

 

Product Description:

“NYU has integrated PDS with Sun’s OpenSSO Identity Management application. The PDS/OpenSSO integration uses PDS as the NYU Libraries’ single sign-on system and leverages NYU’s OpenSSO system to provide seamless interaction between library applications and university services. The integration merges patron information from OpenSSO (e.g. name, email, e-resources access) with patron information from Aleph (e.g. borrower status and type) to ensure access to the multitude of library services.”

“The NYU Libraries operate in a consortial environment in which not all users are in OpenSSO and not all OpenSSO users are in Aleph. PDS is hosted in an active/passive capacity on our Primo front-end servers. Due to the nature of PDS and Aleph, patrons are required to have an Aleph account in order to login to the library’s SSO environment. The exception to this rule is EZProxy.”

 

 

(2) Vulnerability Details:

NYU OpenSSO Integration has a security problem. It is vulnerable to Open Redirect Attacks.
(2.1) The vulnerability occurs at “PDS” service’s logon page, with “&url” parameter.
