Simply use SSH to check if your shop is patched
You can scan your site with magereport.com to see if a patch is installed or not. If a check comes up grey it’s possible the files that are needed for the check are relocated. Therefore it can’t see whether your shop is patched or not. No worries. Simply use SSH to check if your shop is patched.
Every check that’s been installed can easily be found in the content of your shop. More specifically it’s logged in app/etc/applied.patches.list
So you run this command 'grep' on SSH to access the list of applied security patches:
grep '|' app/etc/applied.patches.list
The output will look like this:
-e 2015-04-14 08:34:22 UTC | SUPEE-5344 | EE_1.14.1.0 | v1 | a5c9abcb6a387aabd6b33ebcb79f6b7a97bbde77 | Thu Feb 5 19:14:49 2015 +0200 | v1.14.1.0..HEAD
