Prior to 1.1.0, the shared authentication validator in src/api/common/src/auth/validator.rs accepts an empty or whitespace-only HTTP Basic password for an account whose password_ext value is missing or empty. SSO-provisioned and migration-created users can have this state, allowing an unauthenticated attacker who knows an affected user's email address and organization to authenticate on protected non-ingestion API routes with the victim's role and permissions. A compromised privileged account can expose or modify telemetry, alerts, streams, users, and security configuration. An account with search permission can submit a DataFusion COPY ... TO statement through the search API to create or overwrite attacker-controlled files at service-process-writable locations, creating a conditional escalation to pre-authentication remote code execution. This issue is fixed in version 1.1.0."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"openobserve","product":"openobserve","versions":[{"version":"\u003c 1.1.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-287"}]}],"references":[{"url":"https://github.com/openobserve/openobserve/commit/46678ea8daba94c3904286471794f80c5a74ecea","source":"security-advisories@github.com"},{"url":"https://github.com/openobserve/openobserve/commit/dc5c657002d97e9e29726cefcadec49cae755e1a","source":"security-advisories@github.com"},{"url":"https://github.com/openobserve/openobserve/pull/15054","source":"security-advisories@github.com"},{"url":"https://github.com/openobserve/openobserve/releases/tag/v1.1.0","source":"security-advisories@github.com"},{"url":"https://github.com/openobserve/openobserve/security/advisories/GHSA-7w4v-2c9r-q94v","source":"security-advisories@github.com"}]}}
