| Package | Affected versions | Patched versions |
|---|---|---|
| github.com/KubeOperator/kubepi | < 1.6.3 | 1.6.3 |
| kubepi | < 1.6.3 | 1.6.3 |
The jwt authentication function of kubepi <= v1.6.2 uses hard-coded Jwtsigkeys, resulting in the same Jwtsigkeys for all online projects. This means that an attacker can forge any jwt token to take over the administrator account of any online project.
session.go, the use of hard-coded JwtSigKey allows an attacker to use this value to forge jwt tokens arbitrarily. The JwtSigKey is confidential and should not be hard-coded in the code.
var JwtSigKey = []byte("signature_hmac_secret_shared_key")
var jwtMaxAge = 10 * time.Minute
type Handler struct {
userService user.Service
roleService role.Service
clusterService cluster.Service
rolebindingService rolebinding.Service
ldapService ldap.Service
jwtSigner *jwt.Signer
}
<= v1.6.2
The vulnerability has been fixed in v1.6.3.
https://github.com/KubeOperator/KubePi/commit/3be58b8df5bc05d2343c30371dd5fcf6a9fbbf8b : JWT key can be specified in app.yml, if leave it blank a random key will be used.
It is recommended to upgrade the version to v1.6.3.
