Description
NiubiGEO before 0.3.2 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to make the server fetch internal addresses by supplying a crafted domain value to POST /audit-plan. Attackers can submit IP literals, localhost, or private and link-local hosts to read loopback, internal-network, or cloud metadata responses returned in the plan's siteEvidence JSON.
