Fixed In:

Opened: Mar 17, 2017
Severity: 4-Minor

Symptoms

The issue occurs when user specifies a URL in an LTM Policy where the path contains the hash (#) character. This character was not considered to be valid, and so the valid-character checking logic treats the URL as invalid.

Impact

User is unable to specify a URL containing the hash (#) character.

Conditions

User specifies a URL, say for forwarding a redirect, that contains a hash (#) character. For example, defining a policy to redirect user connections to a URL like: http://www.example.com/path1/path2/#/otherpath

Workaround

In some instances, it may be possible to substitute the hash character (#) with its URL-encoded equivalent (%23).

Fix Information

URLs used in LTM Policies correctly treat the hash character (#) as an allowed character.
