HTTP response splitting vulnerability in index.php in phpSysInfo 2.4 and earlier, as used in phpgroupware 0.9.16 and earlier, and egroupware before 1.0.0.009, allows remote attackers to spoof web content and poison web caches via CRLF sequences in the charset parameter.
phpSysInfo 2.3 allows remote attackers to obtain sensitive information via a direct request to (1) class.OpenBSD.inc.php, (2) class.NetBSD.inc.php, (3) class.FreeBSD.inc.php, (4) class.Darwin.inc.php, (5) XPath.class.php, (6) system_header.php, or (7) system_footer.php, which reveal the path in a PHP error message.
Multiple cross-site scripting (XSS) vulnerabilities in phpSysInfo 2.3, when register_globals is enabled, allow remote attackers to inject arbitrary web script or HTML via the (1) sensor_program parameter to index.php, (2) text[language], (3) text[template], or (4) hide_picklist parameter to system_footer.php.
