Authenticated file disclosure via log path traversal
Published Sep 30, 2022 · Updated May 20, 2025
Path traversal in DNN Platform before 9.11.0 allows remote authenticated users to read files via crafted log-file names. The GetLogFile and GetUpgradeLogFile handlers combined attacker-controlled names with trusted log directories without reducing them to a basename, so relative components could escape the intended directory. Access requires an authenticated account with the relevant log-viewing privilege, and the demonstrated consequence is confidential file disclosure rather than modification or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
