Title: PEAR-Auth: Potential authentication bypass (GLSA 200603-13)
Severity: normal
Exploitable: remote
Date: March 17, 2006
Bug(s): #123832
ID: 200603-13

Synopsis

PEAR-Auth did not correctly verify data passed to the DB and LDAP containers, thus allowing to inject false credentials to bypass the authentication.

Background

PEAR-Auth is a PEAR package that provides methods to create a PHP based authentication system.

Affected Packages

Package: dev-php/PEAR-Auth
Vulnerable: < 1.2.4
Unaffected: >= 1.2.4
Architectures: All supported architectures


Description

Matt Van Gundy discovered that PEAR-Auth did not correctly validate data passed to the DB and LDAP containers.

Impact

A remote attacker could possibly exploit this vulnerability to bypass the authentication mechanism by injecting specially crafted input to the underlying storage containers.

Workaround

There is no known workaround at this time.

Resolution

All PEAR-Auth users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-Auth-1.2.4"


References

CVE-2006-0868
