From: Ramon Medeiros <ramonn@linux.vnet.ibm.com> To prevent brute force attack, creates a mechanism to allow 3 tries first. After that, a timeout will start and will be added 30 seconds for each failed try in a row. Signed-off-by: Ramon Medeiros <ramonn@linux.vnet.ibm.com> --- Changes: v5: Friendly error message Set maximum tries to 3 v4: Use API.json for input validation v3: Improve error handling on login page v2: Set timeout by user, ip and session id. This will avoid trouble with users using the same ip, like NAT. src/wok/API.json | 25 +++++++++++++++++- src/wok/i18n.py | 7 +++-- src/wok/root.py | 69 +++++++++++++++++++++++++++++++++++++++++------- ui/js/src/wok.login.js | 19 ++++++++----- ui/pages/i18n.json.tmpl | 5 +++- ui/pages/login.html.tmpl | 6 ++--- 6 files changed, 107 insertions(+), 24 deletions(-) diff --git a/src/wok/API.json b/src/wok/API.json index XXXXXXX..XXXXXXX 100644 --- a/src/wok/API.json +++ b/src/wok/API.json @@ -XXX,XX +XXX,XX @@ "$schema": "http://json-schema.org/draft-03/schema#", "title": "Wok API", "description": "Json schema for Wok API", - "type": "object" + "type": "object", + "properties": { + "wokroot_login": { + "type": "object", + "properties": { + "username": { + "description": "Username", + "required": true, + "type": "string", + "minLength": 1, + "error": "WOKAUTH0003E" + }, + "password": { + "description": "Password", + "required": true, + "type": "string", + "minLength": 1, + "error": "WOKAUTH0006E" + } + }, + "additionalProperties": false, + "error": "WOKAUTH0007E" + } + } } diff --git a/src/wok/i18n.py b/src/wok/i18n.py index XXXXXXX..XXXXXXX 100644 --- a/src/wok/i18n.py +++ b/src/wok/i18n.py @@ -XXX,XX +XXX,XX @@ messages = { "WOKASYNC0003E": _("Timeout of %(seconds)s seconds expired while running task '%(task)s."), "WOKASYNC0004E": _("Unable to kill task due error: %(err)s"), - "WOKAUTH0001E": _("Authentication failed for user '%(username)s'.
