Gentoo Linux Security Advisory

Title: phpBB: Cross-Site Scripting Vulnerability (GLSA 200505-10)
Severity: normal
Exploitable: remote
Date: May 14, 2005
Bug(s): #90213
ID: 200505-10

Synopsis


phpBB is vulnerable to a cross-site scripting attack that could allow
arbitrary scripting code execution.


Background


phpBB is an Open Source bulletin board package.


Affected Packages

Package: www-apps/phpBB
Vulnerable: < 2.0.15
Unaffected: >= 2.0.15
Architectures: All supported architectures


Description


phpBB is vulnerable to a cross-site scripting vulnerability due to
improper sanitization of user supplied input. Coupled with poor
validation of BBCode URLs which may be included in a forum post, an
unsuspecting user may follow a posted link triggering the
vulnerability.


Impact


Successful exploitation of the vulnerability could cause arbitrary
scripting code to be executed in the browser of a user.


Workaround


There are no known workarounds at this time.


Resolution


All phpBB users should upgrade to the latest version:
Code:

    emerge --sync
    emerge --ask --oneshot --verbose ">=www-apps/phpBB-2.0.15"
