Technical Description

Multiple vulnerabilities were identified in LinPHA, which may be exploited by attackers to execute arbitrary commands or disclose sensitive information.

The first flaw is due to an input validation error in the "docs/index.php" script that fails to properly validate the "lang" parameter, which may be exploited by remote attackers to include local files.

The second issue is due to an error in the "Logger" plugin that does not properly validate the "username" parameter before being logged to a file, which could be exploited by remote attackers to inject malicious PHP code to the log file and execute arbitrary commands in combination with the first issue.

Other vulnerabilities were identified in the "install/install.php", "install/sec_stage_install.php", "install/third_stage_install.php" and "forth_stage_install.php" scripts when processing the "language" variable, which could be exploited by remote attackers to include and read local files.
