Directory traversal vulnerability in phpSysInfo 2.1 and earlier allows attackers with write access to a local directory to read arbitrary files as the PHP user or cause a denial of service via .. (dot dot) sequences in the (1) template or (2) lng parameters.

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.

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.

Directory traversal vulnerability in index.php in phpSysInfo 2.5.1 allows remote attackers to determine the existence of arbitrary files via a .. (dot dot) sequence and a trailing null (%00) byte in the lng parameter, which will display a different error message if the file exists.

Cross Site Request Forgery (CSRF) vulnerability in Phpsysinfo version 3.4.3 allows a remote attacker to obtain sensitive information via a crafted page in the XML.php file.
