Apache Tika Server exposes sensitive information

Moderate severity GitHub Reviewed Published Oct 17, 2018 to the GitHub Advisory Database • Updated Sep 12, 2023

Package

maven org.apache.tika:tika-server (Maven)

Affected versions

< 1.10

Patched versions

1.10

Description

Apache Tika provides optional functionality to run itself as a web service to allow remote use. When used in this manner,
it's possible for a 3rd party to pass a 'fileUrl' header to the Apache Tika Server (tika-server) before version 1.10. This header lets a remote client request that the server fetches content from the URL provided, including files from the server's local filesystem. Depending on the file permissions set on the local filesystem, this could be used to return sensitive content from the server machine.

This vulnerability only exists if you are running the tika-server version 1.9, and you allow un-trusted access to the tika-server
URL. Usage of Apache Tika as a standard library is not affected.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
