CVE-2021-37500Network attack vector

Authenticated arbitrary file overwrite via diagnostics path traversal

Published Jan 20, 2023 · Updated Jul 9, 2026

Path traversal in Reprise License Manager before 14.2BL4 allows remote authenticated users to overwrite any server file. The web interface's diagnostics function accepts a user-controlled path for a file-write operation without confining the resolved path to the intended directory. Access requires an RLM account with sufficient privileges, and the documented consequence is arbitrary file overwrite rather than file disclosure.
