Title:
V3 Authentication Chaining - uniqueness of auth method names
Status in OpenStack Identity (Keystone):
In Progress
Status in OpenStack Security Advisories:
New
Bug description:
In V3.0 API, we can chain authentication methods. An attacker can
place the same authentication method multiple times in the methods
filed. This will result in the same authentication method checking
over and over (for loop in code). Using this, an attacker can achieve
some sorts of Denial of Service. The methods field is not properly
sanitized.
{
"auth":{
"identity":{
"methods":[
"password",
"password",
"password",
"password",
"password"
],
"password":{
"user":{
"domain":{
"id":"default"
},
"name":"demo",
"password":"stack"
}
}
}
}
