phpSysInfo: IP allowlist (PSI_ALLOWED) bypass via spoofed X-Forwarded-For / Client-IP headers
phpSysInfo is a customizable PHP script that displays system information. Prior to 3.4.6, the PSI_ALLOWED access-control check in read_config.php trusts attacker-controlled X-Forwarded-For and Client-IP HTTP headers before REMOTE_ADDR. A remote unauthenticated attacker can supply an allowed address in one of these headers to impersonate a trusted client and access exposed hostname, kernel, CPU, memory, filesystem, and network-interface information. This issue is fixed in version 3.4.6.
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.
Cross-site scripting (XSS) vulnerability in index.php in phpSysInfo 2.5.4-dev and earlier allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO.
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.
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.
Multiple directory traversal vulnerabilities in index.php in phpSysInfo 2.4 and earlier, as used in phpgroupware 0.9.16 and earlier, and egrouwpware before 1.0.0.009, allow remote attackers to include arbitrary files via .. (dot dot) sequences in the (1) sensor_program parameter or the (2) _SERVER[HTTP_ACCEPT_LANGUAGE] parameter, which overwrites an internal variable, a variant of CVE-2003-0536. NOTE: due to a typo in an advisory, an issue in osh was inadvertently linked to this identifier; the proper identifier for the osh issue is CVE-2005-3346.
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.
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.
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.
