The POST parameter session token W2E_SSNID appears as follows:W2E_SSNID=3DW90NIxGoSsN1023ZYW2E735182000013CLSpKfgkCJSLKsc600061JKenjKnE JuNX9GoVjCEbqIuKh6kFRvbzYnUxgQtONszJldyAar3LtTSwsmBLpdlPc5iDH4Zf75 However, this token is poorly validated, leading toW2E_SSNID=3DW90NIxGoSsN1023ZYW2E735182000013being accepted as a valid session. By incrementing and decrementing the digits at the end of the value given above, it is possible to control the session at the given ID. This token is sent as part of the login page, and as such, can be manipulated by an unauthenticated attacker, giving them access to any valid session. Consequentially, it is possible to access the following page as such:https://app.domain.co.uk/web2edoc/close.htm？SSNID=3DW90NIxGoSsN1023ZYW2E735182000026Ending the session specified, which could lead to a denial of service condition.Further details at: http://portcullis-security.com/security-research-and-downloads/security-advisories/cve-2014-1219/ Copyright: Copyright （c） Portcullis Computer Security Limited 2014, All rights reserved worldwide.
