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	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Product: Confluence Vendor: Atlassian Version: 3.0 / Current Tested Version: 3.4.6 Vendor Notified Date: June 31, 2011 Release Date: September 19, 2012 Risk: Medium Authentication: Depends on configuration. Remote: Yes Description: Multiple Cross-Site Request Forgery (CSRF) vulnerabilities in Confluence 3.0 and below allow remote attackers to submit actions on their behalf. Newer versions may also be vulnerable. Pages that allow a potential attacker to add images (such as in the comments sections) allow CSRF. By not properly checking each URL, an attacker can execute requests on behalf of a legitimate user. As a proof-of-concept, a comment is added to a page which includes the logout URL inside the wiki markup image tags. Whenever anyone visits that page they are automatically logged out because the page attempts to load the image and executes the 'src=url'. This comment can be added to anyone's profile, which would force them to be logged out the moment they login. This can be used for more complex attacks too but going beyond the POC was not necessary. Exploit POC: 1. Add comment. 2. !http://pwndshop.com/logout.action|border=1! Vendor Notified: Yes Vendor Response: Requested time to resolve. Vendor Update: 1.5 years later, marked as "Resolution: Won't Fix" Reference: https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF) Credit: Robert Gilbert Senior Consultant HALOCK Security Labs, Purpose Driven Security(tm) rgilbert [-at-] halock [-dot-] com http://www.halock.com http://blog.halock.com Note: This message (including any attachments) is intended only for the use of the individual or entity to which it is addressed and may contain information that is non-public, proprietary, privileged, and/or confidential.
