vulnerability analysis and mitigation

CVE-2024-3845 is a security vulnerability discovered in Google Chrome's network implementation prior to version 124.0.6367.60. The vulnerability allows a remote attacker to bypass mixed content policy through a crafted HTML page. This security issue was disclosed on April 16, 2024, and was assigned a low severity rating by the Chromium security team (Chrome Release).

The vulnerability stems from an inappropriate implementation in the Networks component of Google Chrome. According to the National Vulnerability Database, it received a CVSS v3.1 base score of 4.3 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. The vulnerability is classified under CWE-358 (Improperly Implemented Security Check for Standard) and CWE-1068 (Inconsistency Between Implementation and Documented Design) (NVD).

The vulnerability's impact is primarily focused on the potential bypass of Chrome's mixed content policy. Mixed content policies are security controls that prevent loading insecure HTTP content in secure HTTPS contexts. A successful exploitation could allow attackers to bypass these security controls, potentially leading to mixed content being loaded in secure contexts (NVD).

The vulnerability has been patched in Google Chrome version 124.0.6367.60. Users and administrators are advised to update to this version or later to mitigate the risk. The fix has been distributed to various platforms, including Windows, Mac, and Linux.
