Jenkins Subversion Plugin cross-site request forgery

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Jenkins (Continuous Integration Software) (version now known). It has been declared as problematic. Affected by this vulnerability is some unknown processing of the component Subversion Plugin. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect integrity. The summary by CVE is:

Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks.

The bug was discovered 07/10/2017. The weakness was shared 10/05/2017 by Jesse Glick with CloudBees, Inc. (Website). The advisory is shared at jenkins.io. This vulnerability is known as CVE-2017-1000085 since 07/13/2017. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 86 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 99574†). The entries VDB-107448, VDB-107450, VDB-107451 and VDB-107452 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
