description

JeeWMS versions before commit 0a610e8178a0a1197e9c6615b58faf67c406d2bc are affected by an unauthenticated path traversal issue. A remote attacker can read files accessible to the application by reaching the affected endpoint with a crafted file-path parameter; no account is required.

mitigation

Update JeeWMS to commit 0a610e8178a0a1197e9c6615b58faf67c406d2bc or a later release containing it. Until updated, restrict unauthenticated access to the affected application endpoint at a reverse proxy or network boundary.
