IMPACT:
Exposure of system information, System access

WHERE:

SOFTWARE:
DoceboLMS 2.x

DESCRIPTION:
rgod has reported two vulnerabilities in DoceboLMS, which can be
exploited by malicious people to disclose system information and
compromise a vulnerable system.

1) Input passed to the "Type" parameter in "connector.php" isn't
properly verified, before it is used to list files and directories.
This can be exploited to list files in arbitrary directories via
directory traversal attacks.

2) An input validation error in the file upload handling where the
file extension of valid images is not properly verified can be
exploited to upload a malicious PHP script to a location inside the
web root.

The vulnerabilities have been reported in version 2.0.4. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified and
validated.

PROVIDED AND/OR DISCOVERED BY:
