How to Fix CVE-2022-1285

To remediate this vulnerability, upgrade all affected Gogs.io/gogs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

gogs.io/gogs fixed: 0.12.8 
Upgrade gogs.io/gogs to 0.12.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for gogs.io/gogs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-1285, inspect your project dependencies for Gogs.io/gogs:

inspect dependencies for gogs.io/gogs

Analyze the terminal output to locate any version of Gogs.io/gogs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.8), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Gogs.io/gogs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The malicious user is able to discover services in the internal network through webhook functionality. All installations accepting public traffic are affected. ### Patches Webhook payload URLs are revalidated before each delivery to make sure they are not resolved to blocked local network addresses. Users should upgrade to 0.12.8 or the latest 0.13.0+dev. ### Workarounds Run Gogs in its own private network. ### References https://huntr.dev/bounties/da1fbd6e-7a02-458e-9c2e-6d226c47046d/ ### For more information If you have any questions or comments about this advisory, please post on https://github.com/gogs/gogs/issues/6901.
