PHProjekt is a project management and coordination tool written in PHP.
Alexios Fakos from n.runs AG has discovered multiple vulnerabilities in PHProjekt, including the execution of arbitrary SQL commands using unknown vectors (CVE-2007-1575), the execution of arbitrary PHP code using an unrestricted file upload (CVE-2007-1639), cross-site request forgeries using different modules (CVE-2007-1638), and a cross-site scripting attack using unkown vectors (CVE-2007-1576).
An authenticated user could elevate their privileges by exploiting the vulnerabilities described above. Note that the magic_quotes_gpc PHP configuration setting must be set to "off" to exploit these vulnerabilities.
There is no known workaround at this time.
All PHProjekt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/phprojekt-5.2.1"
