CVE-2023-5673:
WordPress vulnerability analysis and mitigation
Overview
CVE-2023-5673 affects the WP Mail Log WordPress plugin versions before 1.1.3. The vulnerability was discovered and disclosed on December 26, 2023. The issue exists in the plugin's file attachment functionality for emails, where improper validation of file extensions allows attackers to upload potentially malicious files (WPScan).
Technical details
The vulnerability stems from insufficient file extension validation when uploading attachments to emails. This security flaw allows attackers with contributor-level access or higher to upload PHP files to the server. The vulnerability has been assigned a CVSS v3.1 base score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating a serious security risk (NVD).
Impact
If exploited, this vulnerability allows attackers to achieve remote code execution on the affected WordPress installation. This could lead to complete server compromise, as the attacker would be able to execute arbitrary PHP code through the uploaded malicious files (WPScan).
Mitigation and workarounds
The recommended mitigation is to update the WP Mail Log plugin to version 1.1.3 or later, which contains the security fix for this vulnerability (WPScan).
