CVE-2020-10506Network attack vector

Arbitrary-file read via path traversal

Published Apr 15, 2020 · Updated Sep 16, 2024

Path traversal in ALLE INFORMATION CO., LTD. School Manage System before 2020 allows remote attackers to read arbitrary files over the network. TWCERT/CC has not disclosed the affected endpoint or parameter, so the precise path-handling operation that fails to constrain attacker-controlled input remains unknown. No authentication or user interaction is required, and the documented consequence is limited to reading files accessible to the application.
