|
|
# Affected Component: "sensor_details.html" webpage the "id" parameter
|
|
|
|
# Security Issue
|
|
# ServersCheck Monitoring Software allows remote attackers to cause a denial of service
|
|
# (menu functionality loss) by creating an LNK file that points to a second LNK file, if this
|
|
# second LNK file is associated with a Start menu item. Ultimately, this behavior comes
|
|
# from a Directory Traversal bug (via the sensor_details.html id parameter) that allows
|
|
# creating empty files in arbitrary directories.
|
|
|
|
# Exploit/POC
|
|
# DOS Command Prompt .LNK under Start Menu change <VICTIM> to desired user.
