Cannot change logo of copied reader studies

Create a reader study with a logo, copy it, try to change the logo on the copied study. You get a 403 rather than being able to change the logo.

I tried to reproduce this issue but I could not.
- I tried to copy the existing reader study (from development fixtures) and changed the logo on the copied study. That worked.
- I created a new reader study with a logo, copied it with a new name, and changed the logo on the copied study. That also worked.
Was this issue encountered in production or local dev?

Gave it a shot myself... no issue detected either!

Thanks for testing it Paul!!

I can still reproduce it on my own reader study! It is named paradigm_2nd_reader_real_2024_12 - I have added you as editor @pkcakeout , maybe you could take a look? Could it be related to the viewer (Cirrus pre-release (public))? This is the one I have been using for 3d ultrasound reader studies - I cannot remember why we went to that and possibly we could go back to the core one by now but I didn't want to break anything!
pkcakeout commented
@keelinm - did you view the video? Is there anything obvious that you might have done differently when you created the copy?
keelinm commented
@pkcakeout further investigation reveals that it is the image itself that is causing the issue - I can choose a different image successfully. The image I wanted to use is attached - I don't know what could be wrong with it!
pkcakeout commented
Can you maybe attach the image in a zip and upload it again? I think that GitHub pre-processes image files for web-display and we cannot see the actual binary data of the image that way...
keelinm commented
here you go @pkcakeout
us3d.zip

Check if there is a difference between development and prod, the image might be being filtered by AWS WAF rules in prod.
ammar257ammar commented
I tried again locally (development) with the image reported to be the issue and all worked as expected (changing logo on both the new reader study and the copied one). Let's see when Paul tries it in production.
pkcakeout commented
Yes... can reproduce now!
I did carry out some more investigation using imagemagic. This might simply be a "slightly corrupted" png? No tools do not seem to have any issue with loading it though, only grand-challenge, so this seems to be something that is particularly picky in our import pipeline.
The output of identify -verbose on the original image provided by keelin is:

So you can see a few sections were added, but I do not see a material difference.
jmsmkn commented
This is indeed a WAF issue then, false positive from that but at least it is resolved.
pkcakeout commented
@keelinm - if you face this issue again, convert the png using some tool. pngcrush does the trick for me. It literally re-encodes the byte stream without affecting the exact pixel values.
chrisvanrun commented
I'd expect the response to signify some kind of AWS WAF bounce.
jmsmkn commented
It does - 403 forbidden.
chrisvanrun commented
It does - 403 forbidden.
Right, but not in any response headers? IIRC we can customize the reponse body / headers for AWS WAF hits.
jmsmkn commented
The 403 forbidden is sufficient information here, the user does not need to know that it is from AWS WAF, they just need to know that they're not allowed to do what they are trying to do, which 403 forbidden is sufficient information for.

True, they would not need to know it's the WAF. Would you agree that there is a difference between:
- a user not being allowed to perform an action
- a user not being allowed to perform an action with a specific item?
My first instinct on getting a forbidden is that I am not allowed to to the action unrelated to the item I am trying to perform the action with. For the latter I'd expect some kind of infomred error. Not sure if WAF allows a distinction between the two.
jmsmkn commented
The WAF errors affect people trying to hack the site, and then false positives like this. This is about the 4th false positive that I can recall this happening in ~3 years, out of the hundreds of millions of requests handled in that time. It is not worth the effort so that the script kids get a nicer looking page.
pkcakeout commented
I think that this also is partially a security thing. If at random the png-byte stream contains virus-code it might be blocked by content scanning. If we inform users that we detected their virus code... [end-of-stream, cross post with james]

Thanks! Your comments make sense and I am enlightened!
