23) Origin validation error

EUVDB-ID: #VU48460

Risk: Medium

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2020-16012

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the way browser handles requests to cross-origin images. When drawing a transparent image on top of an unknown cross-origin image, the Skia library drawImage function takes a variable amount of time depending on the content of the underlying image. This results in cross-origin information exposure of image content through timing side-channel attacks.

Mitigation
