CERT-In Alerts Mozilla Firefox Users to Update their Browsers Immediately – Disposable mail news

Mozilla Firefox users are receiving alerts regarding multiple vulnerabilities in the web browser by the Indian Computer Emergency Response Team (CERT-In). An advisory has also been issued in the regard asking the users to update their web browsers as soon as possible.

While rating the severity of the vulnerability as ‘High’ on all the versions of Mozilla Firefox that have been released before version 75 and version 68.7 on Mozilla Firefox ESR, the CERT-In stated in the advisory that remote hackers can take advantage of these browser flaws to acquire sensitive data through the browser.

According to the CERT-In advisory, “Out-of-Bounds Read Vulnerability in Mozilla Firefox ( CVE-2020-6821 ). This vulnerability exists in Mozilla Firefox due to a boundary condition when using the WebGLcopyTexSubImage method. A remote attacker could exploit this vulnerability by specially crafted web pages. Successful exploitation of this vulnerability could allow a remote attacker to disclose sensitive information,”

“Information Disclosure Vulnerability in Mozilla Firefox ( CVE-2020-6824). This vulnerability exists in Mozilla Firefox to generate a password for a site but leaves Firefox open.A  remote attacker could exploit this vulnerability by revisiting the same site of the victim and generating a new password. The generated password will remain the same on the targeted system,” the advisory further reads.

The aforementioned vulnerability also allows the attacker to execute ‘arbitrary code’ on the targeted system, letting them run any chosen command onto it. As per sources, another flaw was also found to be existing in the internet browser that concerns with a boundary condition in GMP Decode Data as images exceeding 4GB are being processed on 32-bit builds. The exploitation of this flaw requires the attacker to trick users into opening specially designed images. Upon successful exploitation, the attacker can yet again execute arbitrary code on the targeted system.

Another way by which a remote attacker can take advantage of this exploit is by convincing a user to install a crafted extension, on doing so the attacker will be able to obtain sensitive information.

Apple Engineers to Standardize the Format of the SMS Messages Containing OTPs – Disposable mail news

A proposal comes from Apple engineers working at WebKit, the core component of the Safari web browser, to institutionalize the format of the SMS messages containing one-time passwords (OTP) that users receive during the two-factor authentication (2FA) login process.

 With 2 basic goals, the proposal aims initially is to introduce a way that OTP SMS messages can be associated with a URL, which is essentially done by adding the login URL inside the SMS itself.

And the second being to institutionalize the format of 2FA/OTP SMS messages, so browsers and other mobile applications can undoubtedly distinguish the approaching SMS, perceive web domain inside the message, and afterward consequently extract the OTP code and complete the login operation moving forward without any further user interaction.

According to the new proposal, the new SMS format for OTP codes would look like below:

747723 is your WEBSITE authentication code. 
@website.com #747723 

The first line, intended for human users, permits them to decide from what site the SMS OTP code originated from and the second line is for both human users as well as for applications and browsers.

 Applications and browsers will consequently extricate the OTP code and complete the 2FA login operation. In the event that there’s a ‘mismatch’ and the auto-complete operation falls flat, human readers will have the option to see the site’s original URL, and contrast it with the site they’re attempting to login.

On the off chance that the two are not similar, at that point, users will be alerted that they’re very a phishing site and forsake their login activity.

When browsers will deliver components for reading SMS OTP codes in the new format, significant providers of SMS OTP codes are required to switch to utilizing it. Starting now, Twilio has already communicated its enthusiasm for actualizing the new arrangement for its SMS OTP administrations. 

Presently, while Apple (WebKit) and Google (Chromium) engineers are quite energetic about the proposition, Mozilla (Firefox) has not yet given an official criticism on the standard yet.
