How to Fix CVE-2019-11229

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

github.com/go-gitea/gitea fixed: 1.7.6 
Upgrade github.com/go-gitea/gitea to 1.7.6
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 github.com/go-gitea/gitea

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-11229, inspect your project dependencies for Github.com/go gitea/gitea:

inspect dependencies for github.com/go-gitea/gitea

Analyze the terminal output to locate any version of Github.com/go gitea/gitea in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.6), 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Github.com/go gitea/gitea, 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

models/repo_mirror.go in Gitea before 1.7.6 and 1.8.x before 1.8-RC3 mishandles mirror repo URL settings, leading to remote code execution.
