Description Sayan Das 2020-06-07 14:13:01 UTC 
Description of problem:

Satellite 6.7 is not accepting the proxy password containing special characters like [ ] @ etc and test connection always fails.

Even if we just mention the password and submit, the password field remains blank.

Version-Release number of selected component (if applicable):
6.7.0

How reproducible:
Always

Steps to Reproduce:
1. Configure a squid proxy with the following details.
hostname: squid.example.com
port: 3128
proxy_username: proxyuser
proxy: password: test]satellite@password+

2. Go to Satellite GUI --> Infrastructure --> HTTP Proxies --> Fill up all the details including the proxy_password, in Test URL mention "https://aws.amazon.com" and then click on "Test Connection".

3. With all options filled up, submit the settings.

4. Now open the newly created proxy and look at the password field.


Actual results:

At Step 2, with test connection, you will get an error pop up saying "bad password component"

At Step 4, we will be able to see that the password is blank


Expected results:

Satellite 6.7 should be able to accept the password with special characters properly and allow it to save\user further from GUI.


Additional info:

If I use the same password from the command line, it will work just fine without escaping anything.

Comment 7 Sayan Das 2020-08-29 14:55:54 UTC 
This problem still exists on Red Hat Satellite 6.8-Beta .
Comment 16 Adam Ruzicka 2021-03-24 10:52:00 UTC 
TL;DR: There is no workaround, we will need to patch foreman and restclient. Foreman patch will be small, restclient patch was already written by ManageIQ folks and we'll just need to borrow it from them.

Notes:
There are two issues at play here.

The first is on our side. We try to stuff the user provided strings into an URI object, but that fails because special characters are not allowed there. If we escape the user provided strings first (turn '@' into '%40' and so on), this part should be resolved.

The other issue is restclient (the library we use for making http requests) does not unescape the proxy username and password, so even if we fix the first issue, then the escaped form will be sent to the proxy and the proxy will reject it. There is a PR[1] opened against restclient which fixes this, but last movement there was in October 2018, so I'm afraid we can't wait for this to be fixed there. Unless I'm missing something the only real option we have is to monkey-patch restclient the same way ManageIQ did[2].

This item was selected for a z-stream release (6.9.3) - can we petition the Foreman maintainers to review this sooner rather than later?

Verified:

Verified with:
- Satellite 6.9.6 snap 1
- katello-3.18.1-3.el7sat.noarch
- foreman-2.3.1.23-1.el7sat.noarch

Test steps:
- Create HTTP Proxy with special characters in password
(Go to Infrastructure > Http Proxies > Click on "New Http Proxy") 
- Fill the details related to HTTP Proxy and click on "Test connection" button.
- Go to Administer > Settings > Content. Set "Default HTTP Proxy" setting.
- Refresh manifest.
- Enable and sync repositories.

Observations:
- "Test connection" button worked as expected.
- Manifest refresh, repository enable/disable and repository sync operation finished successfully. 

Additional info:
- Tried following Http proxy password combination:
    - t]se@pa+@#$%^
    - test]satellite@password+
    - t]se@pa+_~-*.,=[
    - a?dd.}v{a
    - test%5Dhttp_password%40password%2B
