Chrome puts billions of users at risk of data theft

Chrome exposes billions of users to the risk of data theft, as a vulnerability in Google’s Chromium-based browsers allows attackers to bypass a content security policy (CSP) on websites in order to implement deceptive code.

And the error was found (CVE-2020-6519) In (Chrome), (Opera) and (Edge) browsers on Windows, Android and Mac.

According to cybersecurity researcher Gal Weizman, this vulnerability has the potential to affect billions of users.

Chrome releases are affected from version 73 (released in March 2019) until version 83 (version 84 was released in July and the issue was fixed).

A content security policy (CSP) is a web standard intended to thwart certain types of attacks, including cross-site scripting (XSS) and data injection attacks.

The CSP standard allows web administrators to specify domains that a browser should consider valid sources for executable scripts.

The CSP-compliant browser executes the scripts loaded into source files received from those domains.

Weizmann said in Search Released Monday: The CSP Standard is the primary method used by website owners to enforce data security policies to prevent malicious code executions on their website.

“When policies can be bypassed, the user’s personal data becomes at risk,” he added.

The researcher pointed out that most websites use (CSP), including internet giants, such as Facebook, Gmail, Instagram and WhatsApp.

Some prominent names were not affected, including (GitHub), Google Play Store, LinkedIn, Paypal, Twitter, and the Yahoo and Yandex login page.

To exploit the vulnerability, the attacker would need access to a web server so that he could modify the JavaScript instructions it uses.

The attacker can then add a (frame-src) or (child-src) directive in JavaScript to allow the injected code to run, bypassing the CSP and the site policy.

The vulnerability is classified as a moderate problem – 6.5 out of 10 on the CvSS scale – but given that it affects the implementation of the CSP standard, this means that it has major implications, and Weizmann compared it to the problem of seat belts and airbags in the car.
