![]() It's a simple, secure, self-service web application that enables end users to manage their network password.As of May 2021, SSPR replaces the Password Manager () for all Staff and Students to recover or reset their network passwords.What is Self Service Password Reset (SSPR)? Tip: Set your Default Sign-in Method, should be set to the most available device you have with you whenever you are signing into a TDSB Accounts e.g. You can choose from different methods: Microsoft Authenticator App, Phone (Cell), Alternate phone, Office Phone, Alternate email, Security questions, etc. It's recommended you should have at least three (2) methods but three (3) would be better to verify your identity "Multi-Factor Authentication" with Microsoft regarding your TDSB Accounts. įor more information please visit Student Virtual Learning IT Support. To first time register, update or make changes to the Self Service Password Reset methods visit. You will be asked to register for the Self-Service Password Reset tool as followsĪ step-by-step guide and a demo video are available to assist you with the registration process. To register for Self Service Password Reset, visit and log into online tools, such as myBlueprint, MyTDSB, Brightspace, Now Mobile or. For students that have already registered, you can disregard this message. Note that email clients typically don't execute JavaScript, but other HTML injection techniques like dangling markup attacks may still apply.The Self-Service Password Reset tool is available to all staff and students and allows you to reset your password without the assistance of your teacher or school staff. In a real attack, the attacker may seek to increase the probability of the victim clicking the link by first warming them up with a fake breach notification, for example.Įven if you can't control the password reset link, you can sometimes use the Host header to inject HTML into sensitive emails. They will then be able to reset the user's password to whatever they like and subsequently log in to their account. The attacker can now visit the real URL for the vulnerable website and supply the victim's stolen token via the corresponding parameter. If the victim clicks this link (or it is fetched in some other way, for example, by an antivirus scanner) the password reset token will be delivered to the attacker's server. However, the domain name in the URL points to the attacker's server: This seems to contain an ordinary link to reset their password and, crucially, contains a valid password reset token that is associated with their account. The victim receives a genuine password reset email directly from the website. When submitting the form, they intercept the resulting HTTP request and modify the Host header so that it points to a domain that they control. The attacker obtains the victim's email address or username, as required, and submits a password reset request on their behalf. If the URL that is sent to the user is dynamically generated based on controllable input, such as the Host header, it may be possible to construct a password reset poisoning attack as follows: How to construct a password reset poisoning attack Password reset poisoning is a method of stealing this token in order to change another user's password. However, its security relies on the principle that only the intended user has access to their email inbox and, therefore, to their unique token. This process is simple enough and relatively secure in comparison to some other approaches. If everything is as expected, the user is given the option to enter a new password. When the user visits this URL, the website checks whether the provided token is valid and uses it to determine which account is being reset. The user's unique reset token is included as a query parameter in the corresponding URL: The website sends an email to the user that contains a link for resetting their password. The website checks that this user exists and then generates a temporary, unique, high-entropy token, which it associates with the user's account on the back-end. The user enters their username or email address and submits a password reset request. ![]() One of the most common approaches goes something like this: There are several ways of doing this, with varying degrees of security and practicality. Virtually all websites that require a login also implement functionality that allows users to reset their password if they forget it. This technique was first documented in 2013 by our Director of Research, James Kettle.Ĭheck out our Research page for full write-ups and video presentations of more innovative techniques discovered by James and the rest of the team.
