tmpfile page contract filter reform:

do not allow acs-subsite TmpDir parameter to define where the tmpfolder is located anymore. This MUST be the one configured in the server-wide configuration. Tmpfiles cannot be in a subfolder of the tmpfolder, they MUST be direct children instead. A tmpfile MUST exist beforehand and be owned, be readable and writable by the user running the nsd process. This complies with the definition of a tmpfile by AolServer/NaviServer when they are created to store content coming from a file upload.

Extend tmpfile filter to behave in the "old way" (default), or in strict mode e.g. tmpfile(strict), enforcing the behavior for tmpfile in Aolserver/Naviserver when a form is processed

Reimplement ad_page_contract_filter_proc_tmpfile using security::safe_tmpfile_p

Some of the features implemented by this filter have been ported into the api, namely the possibility to fetch the valid temp folders from the subsite TmpDir parameter and the possibility to relax the check and allow also files deeper in the tmpfolder hierachy.

Notably, the hardcoded tmpfolders "/var/tmp" and "/tmp" have NOT been ported. One should configure these values via the many available options. security::safe_tmpfile_p is also more restrictive when a file exists, because it checks for ownership and read and write permissions on the file.

Comment WIP

Declare proc coverage

Factor the payload building behavior in util::http::post into its own proc, so that it can be reused elsewhere

Make also sure the tmpfile from the widget exists beforehand, when validating: we don't want users to "explore" our tmpdir with bogus values that just look sane

Add must_exist flag to enforce a safe tmpfile to already exist

Fixed bug in util_convert_line_breaks_to_html

The code deleted spaces around certain tags, while - according to the

documentation, only line breaks should be removed from there.

Extended regression test.

Improve doc

Revert to previous template::widget::file behavior of accepting input in a form of a list of 3 elements (e.g. without a .tmpfile in the request), but introduce validation so that we enforce all widget values to be in the proper format and the files to be "safe"

file file-procs.tcl was initially added on branch oacs-5-10.

Bring test closer to reality

Introduce security::safe_tmpfile_p checking whether a file belongs to the configured tmpfolder and respects other constraints

The plan is to use it to improve input validations

Fixed serious bug killing at least short-text questions in inclass exam

The bug was introduced in [1], by testing for the existence of the

disabled attribute, and when it exists, it was omitting values

reading. The problem is that when form-fields are reset, the

"disabled" attribute is set to 0, leading the exists check to

succeed. In essence, This change sets now the default value of the

form-field to "0", such that it is safe to test it everywhere.

Originally, it was not set by default to save resources (memory and

processing power), but this requires a more careful analysis when

changes happen.

Tighten test for is_wf_instance

Previously, the test was based on setting of state and FormPage.

In cases, where plain FormPages are used inside an xowf package

this test was leading to wrong results.

Deactivated script-dynamic again

activating "script-dynamic" for script-src prevents resources as the following from loading

improve test coverage of apm_* API

reduce verbosity

added test for checking documentation in regard of valid HTML markup

Test the behavior of the file-storage when a malicious user would try to store a pre-existing file on the server as its own

The fix for the file-storage is a simple validation to make sure that the tmpfile exists, however, for the generic case of the file widget, we cannot trust the tmpfile value when this was not generated by the server. This will probably cause regression when one wants to show a "preview" of a form, to be continued.

Whitespace cleanup

replace occurrences of <br/> in api doc strings

Properly escape "<" and ">" in api-doc documentation.

Since all documentation is rendered via HTML, the characters

"<" and ">" have to be HTML-quoted, otherwise strange things

(omission, unintended renderings) might occur.

E.g. the sentence

Define an interface between a page and an

ADP <include> similar to the page_contract.

was rendered as

Define an interface between a page and an

ADP similar to the page_contract.

which is incorrect.

Incorporate feedback from downstream penetration tests:

do not skip basic validation in the file widget when a tmpfile is not found in the request.
