Severity: 3-Major

Symptoms

If a URL contains backslashes in the query and/or in fragment parts, it may not be handled correctly in some cases for Internet Explorer and Chrome.

Impact

Query and/or fragment part of this URL may be mangled by replacing backslashes. In the example, the query part may be converted to the following string: ?param=aaa/bbb. This may lead to incorrect behavior of web applications.

Conditions

- HTML page with dynamically generated URL with backslashes in query and/or fragment parts, for example: http://example.com/some/file.html?param=aaa\bbb. - Internet Explorer or Chrome browser.

Workaround

Use an iRule to correct query/fragment part string.

Fix Information

Now URLs with backslashes in query and/or fragment parts are handled correctly by Portal Access.
