Background
The github.com/go-gitea/gitea/models package is a component of Gitea, an open-source self-hosted Git service. It provides functionality for managing repository settings, including the form.MirrorAddress field. This vulnerability affects Gitea versions before 1.7.6 and 1.8.x before 1.8-RC3. The package fails to validate the form.MirrorAddress input before saving it, leading to potential security issues.
Vulnerability Detail
The vulnerability arises from the lack of input validation in the repo/setting.go file of the github.com/go-gitea/gitea/models package. Specifically, the form.MirrorAddress field is not properly validated before being saved. This oversight allows an attacker to manipulate the MirrorAddress field and potentially execute malicious actions. The impact of this vulnerability can range from unauthorized access to sensitive information to remote code execution.

Workaround
As a temporary workaround, users can manually validate the form.MirrorAddress input before saving it. This can be done by implementing custom validation logic in the repo/setting.go file. Here is an example of how the validation can be performed:
def validateMirrorAddress(address string) bool {
// Perform validation logic here
// Return true if the address is valid, false otherwise
}
func SaveAddress(address string) {
if validateMirrorAddress(address) {
// Save the address
} else {
// Handle invalid address
}
}
Conclusion
In conclusion, the github.com/go-gitea/gitea/models package in Gitea is vulnerable to improper input validation in the form.MirrorAddress field. This vulnerability can be mitigated by updating Gitea to version 1.7.6 or later. Users can also manually validate the input as a temporary workaround.
