Description:
Some vulnerabilities have been discovered in Claroline, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "clarolineRepositorySys" and "includePath" parameters in various scripts in the "claroline/auth/extauth/drivers/" directory, the "claro_CasLibPath" parameter in "claroline/auth/extauth/casProcess.inc.php", the "includePath" parameter in "claroline/inc/lib/event/init_event_manager.inc.php", and the "rootSys" and "clarolineRepositoryAppend" parameters in "claroline/inc/lib/export_exe_tracking.class.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.
Successful exploitation requires that "register_globals" is enabled.
The vulnerabilities have been confirmed in version 1.7.5 and also reported in version 1.6.4. Prior versions may also be affected.
