Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to the ManifestParser class used by the repo command and the AmazonS3 class used to implement the experimental amazons3 git transport protocol allowing to store git pack files in an Amazon S3 bucket. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
