Topic :

Oracle Application Server 10G ORA_DAV Basic Authentication Bypass Vulnerability

SecurityAlert : 3867

CVE : CVE-2008-2138

SecurityRisk : Medium Security Risk Medium

(About)

Remote Exploit : Yes

Local Exploit : No

Exploit Available : No

Credit : Deniz Cevik

Published : 12.05.2008

Affected Software :

Oracle Application Server 10G

Advisory Content :

Affected Software/Device: Oracle Application Server Portal

Vulnerability: Authentication Bypass

Tested Version: 10G

Risk: Medium

Description:

Oracle Application Server Portal (OracleAS Portal) is a Web-based
application for building and deploying portals. It provides a secure,
manageable environment for accessing and interacting with enterprise
software services and information resources.

Initially /dav_portal/portal/ directory is being protected using basic
authentication. It is possible to bypass and access content of
dav_portal by adding a specially crafted cookie value in the http
request header.

Sample Request:

In order to construct a special http request first visit
"http:/site/pls/portal/%0A" url. This request adds special session id
into cookie. Subsequent connection attempts to
"http://site/dav_portal/portal/" will reveal the contents of directory
without any authentication.
