Detailsinfo

A vulnerability classified as critical has been found in Apache Tomcat up to 8.5.15/9.0.0.M21 (Application Server Software). This affects some unknown functionality of the component HTTP2. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M21 and 8.5.0 to 8.5.15 bypassed a number of security checks that prevented directory traversal attacks. It was therefore possible to bypass security constraints using a specially crafted URL.

The bug was discovered 08/10/2017. The weakness was shared 08/11/2017 by Security Team with Apache (Website). It is possible to read the advisory at lists.apache.org. This vulnerability is uniquely identified as CVE-2017-7675 since 04/11/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation.
