[Bug 33144] New: Authority lookup in advanced editor overencodes HTML
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33144 Bug ID: 33144 Summary: Authority lookup in advanced editor overencodes HTML Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: Cataloging Assignee: koha-bugs@lists.koha-community.org Reporter: phil@chetcolibrary.org QA Contact: testopia@bugs.koha-community.org CC: jonathan.druart+koha@gmail.com, m.de.rooy@rijksmuseum.nl Depends on: 26102 Bug 26102 prevented XSS via malicious authority records (which would have been fun to exploit), but it did it by creating an HTML entity-encoded string and then handing it to a function which expected to get text, not HTML. As a result, if you look up the authority record for Simon & Schuster Audio (Firm) from the advanced editor, you wind up putting Simon & Schuster Audio (Firm) in your bib record. Steps to reproduce: 1. Set EnableAdvancedCatalogingEditor to Enable 2. Edit any Topical Term authority record, and at the end of 150 subfield a add (without the newlines, just offsetting it for easy copying) & Stuff </script><script>alert('boo ❤')</script> 3. Cataloging - Advanced Editor 4. Hit return in the editor to get a new line, type 650 and press tab three times, then Ctrl+Shift+L 5. Search for the authority you edited, click Choose Expected result: The editor should show 650 _ 4 ‡aAbduction & Stuff </script><script>alert('boo ❤')</script>‡vDrama. since that's the text of the authority you selected Actual result: The editor shows 650 _ 4 ‡aAbduction & Stuff </script> <script>alert('boo ❤');</script>‡vDrama.

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33144 --- Comment #1 from Phil Ringnalda <phil@chetcolibrary.org> --- Created attachment 147776 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=147776&action=edit Bug 33144: Unescape text from authority lookup for advanced editor While the basic editor is happy with an array of subfields it can stuff into separate fields, the advanced editor needs to get a JS string back from the authority lookup plugin, because it is going to just add the whole thing as text. The string has to be HTML entity encoded, both to not allow XSS and just to not break the window, but it needs to then be unencoded before being inserted into the editor. Test plan: 1. Set the system preference EnableAdvancedCatalogingEditor to Enable 2. Edit any Topical Term authority, and at the end of tag 150 subfield a, add & </script> 3. Cataloging - Advanced editor 4. Press return in the editor to get a new blank line, type 650 and press tab three times, then type Ctrl-Shift-L 5. Search for your modified authority, and click Choose 6. Verify that the tiny popup opened by the search window finished its job and closed itself 7. Verify that your 650 now shows as "‡aAbduction & </script>‡vDrama" rather than "‡aAbduction & </script>‡vDrama." -- You are receiving this mail because: You are watching all bug changes.
