Rename folders "OCP\Files\ForbiddenException: Access denied"

Open aleadco opened this issue 4 years ago • 10 comments

Steps to reproduce

A flow has been created inside a folder that has an invisible label. The rule is as follows:

  1. If it's tagged with X rule:
  2. Lock non-office files
  3. Lock non-PDF files
  4. Lock files other than folders
  5. Block files that do not match ZIP.

Apparently everything works execpt when you try to rename a created folder.

The files can be renamed without difficulty.

Expected behaviour

Being able to rename the folders created within the flow.

Actual behaviour

[webdav] Fatal: Access denied

Can you post a screenshot of the rules so we can more easily rebuild them locally?

nickvergessen avatar May 10 '23 14:05 nickvergessen

this seems to be still an issue. NC 28.0.2 (docker version with apache) on ubuntu 22.04 files access control with multiple restrictions for different groups creating and deleting folders is possible renaming triggers "access forbidden"

"more easily rebuild" ... hmm ... you asked for it ... it is a really long ruleset in this case. But it is failing because of the "folders" part - i am sure. The problem occured after the update to nc28.0.2

here is an outtake of the database entries: oc_flow_operations: "9" "OCA\FilesAccessControl\Operation" "" "[8,29,34,35,38,39,40,41,42,43,44,45,46,47,48,49,50,56,57,63,64,65,66,67,68,69,85,112,113,111,115]" "deny" "OCA\WorkflowEngine\Entity\File" "[]" "11" "OCA\FilesAccessControl\Operation" "" "[29,34,35,45,8,44,46,47,48,49,50,43,38,39,40,41,42,56,57,63,64,65,66,67,68,69,112,113,77,111,115]" "deny" "OCA\WorkflowEngine\Entity\File" "[]" "12" "OCA\FilesAccessControl\Operation" "" "[29,34,35,45,8,44,46,47,48,49,50,43,38,39,40,41,42,56,57,63,64,65,66,67,68,69,36,37,51,52,71,72,73,75,88,107,108,111,112,113]" "deny" "OCA\WorkflowEngine\Entity\File" "[]" "13" "OCA\FilesAccessControl\Operation" "" "[29,34,35,45,8,44,46,47,48,49,50,43,38,39,40,41,42,56,57,63,64,65,66,67,68,69,73,72,71,36,37,51,52,75,107,108,111,112,113,89,116,117]" "deny" "OCA\WorkflowEngine\Entity\File" "[]" "14" "OCA\FilesAccessControl\Operation" "" "[34,35,45,8,44,46,47,48,49,50,43,38,39,40,41,42,56,57,63,64,65,66,67,68,69,73,72,71,36,37,51,52,75,107,108,111,112,113,90,29]" "deny" "OCA\WorkflowEngine\Entity\File" "[]" "15" "OCA\FilesAccessControl\Operation" "" "[8,35,34,29,111,115,118]" "deny" "OCA\WorkflowEngine\Entity\File" "[]"

@nickvergessen I can reproduce on NC master (30).

  • Add a flow to block file access if it's not a folder image
  • Folder creation still works but renaming does not image

Log from the exception: rename.txt

Maybe $isDir could be set in files_accesscontrol/lib/StorageWrapper.php in the rename method. https://github.com/nextcloud/files_accesscontrol/blob/main/lib/StorageWrapper.php#L206-L207

Maybe $isDir could be set in files_accesscontrol/lib/StorageWrapper.php in the rename method.

https://www.youtube.com/watch?v=2lz4ipB168A How would we know it's not renaming a file/executable without an extension?

I guess same problem applies to copy, copyFromStorage, moveFromStorage and many more...

nickvergessen avatar Apr 22 '24 19:04 nickvergessen

@nickvergessen Isn't there a way to get the node from the path and check if it's a folder? I guess you're implying that it's not possible to do so in StorageWrapper...

Any idea how this issue could be solved?

julien-nc avatar Apr 23 '24 09:04 julien-nc

Don't create a rule which only allows folders... I know it's not the solution and guess the problem can be created with more complex rules that actually make sense.

I'll take a look soon
