VCLU-70-000003 - Lookup Service must limit the maximum size of a POST request.

Information

The 'maxPostSize' value is the maximum size in bytes of the POST that will be handled by the container FORM URL parameter parsing. Limit its size to reduce exposure to a denial-of-service attack.

If 'maxPostSize' is not set, the default value of 2097152 (2MB) is used. Lookup Service is configured in its shipping state to not set a value for 'maxPostSize'.

Solution

Navigate to and open:

/usr/lib/vmware-lookupsvc/conf/server.xml

In the <Connector> node, remove the 'maxPostSize' key/value pair.

Restart the service with the following command:

# vmon-cli --restart lookupsvc
