GLSA-200511-18 : phpSysInfo: Multiple vulnerabilities
Medium Nessus Plugin ID 20262
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200511-18 (phpSysInfo: Multiple vulnerabilities)
Christopher Kunz from the Hardened-PHP Project discovered that phpSysInfo is vulnerable to local file inclusion, cross-site scripting and a HTTP Response Splitting attacks.
A local attacker may exploit the file inclusion vulnerability by sending malicious requests, causing the execution of arbitrary code with the rights of the user running the web server. A remote attacker could exploit the vulnerability to disclose local file content.
Furthermore, the cross-site scripting issues gives a remote attacker the ability to inject and execute malicious script code in the user's browser context or to steal cookie-based authentication credentials.
The HTTP response splitting issue give an attacker the ability to perform site hijacking and cache poisoning.
There is no known workaround at this time.
SolutionAll phpSysInfo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-apps/phpsysinfo-2.4.1'
