CSRF in Apache Jackrabbit WebDAV Content-Type Check

IdentifiersCVE-2016-6801CWE-352· Cross-Site Request Forgery (CSRF)

CVE-2016-6801 is a cross-site request forgery vulnerability in the CSRF content-type check implemented by Jackrabbit-Webdav in Apache Jackrabbit. Affected versions are 2.4.x before 2.4.6, 2.6.x before 2.6.6, 2.8.x before 2.8.3, 2.10.x before 2.10.4, 2.12.x before 2.12.4, and 2.13.x before 2.13.3. The flaw allows the CSRF protection logic for resource-creation HTTP POST requests to be bypassed when the request uses a missing or crafted Content-Type header. As a result, an attacker can cause a victim's authenticated browser or client context to submit unintended WebDAV resource-creation requests under the victim's session.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to hijack an authenticated victim's session context for HTTP POST requests that create resources in the Jackrabbit WebDAV application. This can result in unauthorized resource creation and other state-changing actions performed with the victim's privileges, compromising integrity and potentially enabling follow-on abuse depending on repository permissions and application workflow.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by restricting access to the WebDAV interface, especially from untrusted networks; require additional anti-CSRF controls beyond Content-Type validation; and limit authenticated browser-based access where feasible. Operationally, minimize the ability of users with active authenticated sessions to be induced to visit attacker-controlled content. These are compensating controls only; upgrading is the definitive fix.

Remediation

Patch, then assume compromise.

Upgrade Apache Jackrabbit jackrabbit-webdav to a fixed release: 2.4.6 or later for the 2.4.x branch, 2.6.6 or later for 2.6.x, 2.8.3 or later for 2.8.x, 2.10.4 or later for 2.10.x, 2.12.4 or later for 2.12.x, or 2.13.3 or later for 2.13.x.
