Phpbb Group: >> Phpbb >> 2.0.17 Security Vulnerabilities
phpBB 2.0.17 and earlier, when register_globals is enabled and the session_start function has not been called to handle a session, allows remote attackers to bypass security checks by setting the $_SESSION and $HTTP_SESSION_VARS variables to strings instead of arrays, which causes an array_merge function call to fail.

Multiple cross-site scripting (XSS) vulnerabilities in phpBB 2.0.17 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) error_msg parameter to usercp_register.php, (2) forward_page parameter to login.php, and (3) list_cat parameter to search.php, which are not initialized as variables.

Interpretation conflict in phpBB 2.0.17, with remote avatars and avatar uploading enabled, allows remote authenticated users to inject arbitrary web script or HTML via an HTML file with a GIF or JPEG file extension, which causes the HTML to be executed by a victim who views the file in Internet Explorer, which renders malformed image types as HTML, enabling cross-site scripting (XSS) attacks. NOTE: it could be argued that this vulnerability is due to a design flaw in Internet Explorer (CVE-2005-3312) and the proper fix should be in that browser; if so, then this should not be treated as a vulnerability in phpBB.
