标题: Oracle GlassFish Server 4.1 - Directory Traversal EDB-ID: 39441 CVE: 2017-1000028 类型: WEBAPPS 平台: MULTIPLE 发布日期: 2015-08-27 漏洞利用脚本: Trustwave SpiderLabs Security Advisory TWSL2015-016:
Path Traversal in Oracle GlassFish Server Open Source Edition

Published: 08/27/2015
Version: 1.0

Vendor: Oracle Corporation (Project sponsored by Oracle)
Product: GlassFish Server Open Source Edition
Version affected:  4.1 and prior versions

Product description:
Built using the GlassFish Server Open Source Edition, Oracle GlassFish
Server delivers a flexible, lightweight and extensible Java EE 6 platform.
It provides a small footprint, fully featured Java EE application server
that is completely supported for commercial deployment and is available as
a standalone offering.

The Administration Console of Oracle GlassFish Server, which is listening
by default on port 4848/TCP, is prone to a directory traversal
vulnerability. This vulnerability can be exploited by remote attackers to
access sensitive data on the server being authenticated.

Finding 1: Directory traversal

#Proof of Concept on Microsoft Windows installation

The authenticated Directory Traversal vulnerability can be exploited by
issuing a specially crafted HTTP GET request utilizing a simple bypass,
%C0%2F instead of (/),URL encoding.
