CVE-2023-6821Public exploitNetwork attack vector

PHP log disclosure via browsable export directory

Published Mar 18, 2024 · Updated Mar 27, 2025

Directory listing in BestWebSoft Error Log Viewer before 1.1.3 allows attackers to download exported PHP logs without authorization. The Save as TXT action places log copies in wp-content/plugins/error-log-viewer/saved_logs, whose contents are exposed to HTTP browsing. An administrator must first use Save as TXT; subsequent visitors can enumerate and retrieve saved logs without authentication.
