OMSA 7.3.0.1 - wpoison (nasl version)

I've been running some vunlnerability assements using the Openvas tool.

After upgrading the OMSA on servers to 7.3.0.1, Openvas shows this for all 1311 tcp ports:

 NVT: wpoison (nasl version) (OID: 1.3.6.1.4.1.25623.1.0.11139)

The following URLs seem to be vulnerable to BLIND SQL injection
techniques : 

/HelpViewer?file=Redirect&app=oma+AND+1=1

An attacker may exploit this flaws to bypass authentication
or to take the control of the remote database.

Solution: Modify the relevant CGIs so that they properly escape arguments

Any clues as to a fix ?

Thanks
