Advisory ID: SYSS-2017-008 Product: agorum core Pro Manufacturer: agorum Software GmbH Affected Version(s): Tested Version(s): Vulnerability Type: Cross-Site Request Forgery (CWE-352) Risk Level: Medium Solution Status: Open Manufacturer Notification: 2017-02-06 Solution Date: 2017-04-06 Public Disclosure: 2017-04-12 CVE Reference: Not yet assigned Author of Advisory: Sascha Grimmeisen & Dr. Erlijn van Genuchten, SySS GmbH ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Overview: agorum core Pro is a module based Document Management System. It allows the customer to buy only required modules and can be extended when needed. Due to missing protection mechanisms, the web application component is vulnerable to cross-site request forgery (CSRF) attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The tested web application component offers no protection against cross- site request forgery (CSRF) attacks. This kind of attack forces end users respectively their web browsers to perform unwanted actions in a web application context in which they are currently authenticated. CSRF attacks specifically target state-changing requests, for example in order to enable or disable a feature, and not data theft, as an attacker usually has no possibility to see the response of the forged request. In general, CSRF attacks are conducted with the help of the victim, for example by a user visiting an attacker-controlled URL sent by e-mail in its web browser. Often, cross-site request forgery attacks make use of cross-site scripting attacks, but this is not mandatory. CSRF attacks can also be performed against a web application if a victim is only visiting an attacker-controlled web server. In this case, the attacker-controlled web server is used to generate a specially crafted HTTP request in the context of the user's web browser which is then sent to the vulnerable target web application. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): The following HTML file containing a web form generates a simple crafted HTTP POST request that can be used to add an administration user to the web application in the context of an administrative user. PoC HTML file to add an administration user 'ADDEDUSER' with the password 'PASSWORD123': <html> <body> <img src="https://[HOST]/roiwebui/roiwebui_module/"> </body> </html> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: Update to agorum core 7.11.3.
