Error: A potentially dangerous Request.Form value

This morning, we discovered an incompatibility between Cablecast and a recent security update from Microsoft (delivered last night via Windows Update). We believe it is related to the update labeled KB939373, described [url="http://www.microsoft.com/technet/security/bulletin/ms07-041.mspx"]here[/url].

If the update has not yet been installed on your system, we recommend not installing it until a Cablecast update is released.

If you are affected by this incompatibility, you will see the following error in various places in Cablecast:

quote:Server Error in '/Cablecast' Application.

A potentially dangerous Request.Form value was detected from the client...

We've seen the error occur in the following scenarios:

• Editing an Event in the Event Table
• Forcing>
• Saving/Updating a Show record

Affected versions:
To the best of our knowledge, the following versions of Cablecast are affected:

• 4.4
• 4.5

(Note that Cablecast 4.6 should not be affected by this issue.)

Workaround:
A workaround is available until a software update can be created. Please contact our technical support department for assistance on applying the workaround.

Software Update:
We will be releasing an update to the 4.5 version as soon as we can. If you are using version 4.4 or earlier, you will need to upgrade to 4.5 or newer, or, continue to use the workaround.

We sincerely apologize for any inconvenience this may have caused. Rest assured that we are working as hard as we can to resolve the issue.
