CVE-2023-0704: 
vulnerability analysis and mitigation

CVE-2023-0704 is a security vulnerability discovered in Google Chrome's DevTools component prior to version 110.0.5481.77. The vulnerability was disclosed on February 7, 2023, and was reported by Rhys Elsmore and Zac Sims of the Canva security team. This vulnerability stems from insufficient policy enforcement in DevTools, which could allow a remote attacker to bypass same origin policy and proxy settings (Chrome Release, NVD).

The vulnerability has been assigned a CVSS v3.1 Base Score of 6.5 (Medium) with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N. The attack requires user interaction and can be exploited remotely. The vulnerability specifically affects the policy enforcement mechanisms in Chrome's DevTools, potentially allowing attackers to bypass security controls via a crafted HTML page (NVD).

The vulnerability could allow remote attackers to bypass same origin policy and proxy settings through a specially crafted HTML page. This could potentially lead to security policy violations and unauthorized access to resources that should be restricted by the same origin policy (Rapid7).

The vulnerability has been patched in Chrome version 110.0.5481.77 and later versions. Users and administrators are advised to update to this version or later to mitigate the vulnerability. The fix has also been incorporated into other Chromium-based browsers, including Microsoft Edge and various Linux distributions (Chrome Release, Debian).
