Last modified

CVE-2023-7335 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. EduSoho versions prior to 22.4.7 contain an arbitrary file read vulnerability in the classroom-course-statistics export functionality. A remote, unauthenticated attacker can supply crafted path traversal sequences in the fileNames[] parameter to read arbitrary files from the server filesystem, including application configuration files such as config/parameters.yml that may contain secrets and database credentials. Exploitation evidence was observed by the Shadowserver Foundation on 2026-01-19 (UTC).. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
