Traffic Totals: Broken in 2.4.4-p3 [SOLVED WITH PATCH]

[jlw52761]

@KOM Got it, thanks!

Which specific privileges do the user have which can't load the graph?

The WebCfg - Status: Traffic Totals (page-status-monitoring) privilege appears to be correct.

What, if anything, shows in the main system log when a non-admin user attempts to access the page?

I only have the single user.

From the FreeRadius users:-

"andy" Cleartext-Password := "password"

	Class := "admins",
	Service-Type := "Administrative-User"

Actually, I see what the problem is. The way the package uses display_top_tabs() to generate tabs that don't link to actual pages, just JS anchors, doesn't like the new stronger page validation used by the privilege system. And since they aren't actual files that exist, there isn't a way to allow access to them, so the privilege system filters out the tabs.

I don't see a quick way to fix this in the package privileges, but maybe the package maintainer can figure out a better way to generate the tab anchor links.

I'll see if I can come up with a safe way to test for this in the privilege matching system.

I think I've got this fixed but it'll take a patch in the base system, not the package.

You can install the System Patches package and then create an entry for bdbd8534eef5b93370065340de225a1cd5e5faa8 to apply the fix and try it out. I did test against several different attack methods to ensure it didn't lower the security, and it allows the JS anchor links as expected.

Thanks for the patch; it fixed the issue. I also applied the User Manager bug patch.

I was prompted to install the User Manager patch after seeing Tom's latest video.

@jimp Thanks for this. One question though. Testing the patch indicates it cannot be backed-out cleanly. Is this something we should be concerned about?

/usr/bin/patch --directory=/ -f -p2 -i /var/patches/5cebf5d50a1d0.patch --check --reverse --ignore-whitespace

Hmm...  Looks like a unified diff to me...

When you test a patch it shows its current status when compared to the file(s) to be patched.

Before you apply it will say:

Patch can be applied cleanly (detail)
Patch can NOT be reverted cleanly (detail)

After it is applied it will say:

Patch can NOT be applied cleanly (detail)
Patch can be reverted cleanly (detail)

@Derelict, ah. okay then.
Thank you.
