David | Last updated: Sep 13, 2018 03:12PM UTC

This is being reported as Client-side JSON injection (DOM-based). The value injected does not match the value that is reported as reaching the sink. Dynamic analysis Data is read from input.value and passed to JSON.parse. The source element has id ctl01_SelectedPersonID and name ctl01$SelectedPersonID. The following value was injected into the source: 956229 The previous value reached the sink as: m35yar%2527%2522`'"/m35yar/><m35yar/\>gt6cgj& Similar issue this is reported as Ajax request header manipulation (DOM-based). The value injected does not match the value that is reported as reaching the sink. Dynamic analysis Data is read from document.cookie and passed to xhr.setRequestHeader.value. The following value was injected into the source: lu1g0u%2527%2522`'"/lu1g0u/><lu1g0u/\>c6c025& The previous value reached the sink as: pevdo1%27%22`'"/pevdo1/><pevdo1/\>uq1rks&

Hi David, yes thanks there is bug. In some sources we display the current source value not the injected one. This will be fixed in a future version of Burp. Thanks for reporting.

Hi David Thanks for your report! This should be fixed in the latest version of Burp.
