Severity:	normal
Title:	PEAR::MDB2: Information disclosure
Date:	12/09/2007
Bugs:	#198446
ID:	200712-05

Synopsis

A vulnerability when handling database input in PEAR::MDB2 allows remote attackers to obtain sensitive information.

Background

PEAR::MDB2 is a database abstraction layer for PHP aimed to provide a common API for all supported relational database management systems. A LOB ("large object") is a database field holding binary data.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-php/PEAR-MDB2	< 2.5.0_alpha1	>= 2.5.0_alpha1	All supported architectures

Description

priyadi discovered that the request to store a URL string as a LOB is treated as a request to retrieve and store the contents of the URL.

Impact

If an application using PEAR::MDB2 allows input of LOB values via a web form, remote attackers could use the application as an indirect proxy or obtain sensitive information, including "file://" URLs local to the web server.

Workaround

As a workaround, manually filter input before storing it as a LOB in PEAR::MDB2.

Resolution

All PEAR::MDB2 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-php/PEAR-MDB2-2.5.0_alpha1"
