CVE-2023-7335

HIGHPre-NVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 49% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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).
