When importing an image from a URL source, the LXD daemon fails to validate or restrict outbound destination IP addresses, allowing connections to loopback, RFC1918 private ranges, and cloud metadata endpoints. This enables error-based port scanning and unauthorized interaction with internal HTTP services from the daemon's network position."},{"lang":"es","value":"En las versiones de Canonical LXD 4.12 a 6.9, una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en la funcionalidad de importación de imágenes permite a los usuarios autenticados con el derecho ’can_create_images’ interactuar con la infraestructura de red interna a través del endpoint /images. Al importar una imagen desde una fuente URL, el demonio LXD no valida ni restringe las direcciones IP de destino salientes, permitiendo conexiones a loopback, rangos privados RFC1918 y endpoints de metadatos de la nube. Esto permite el escaneo de puertos basado en errores y la interacción no autorizada con servicios HTTP internos desde la posición de red del demonio."}],"affected":[{"source":"security@ubuntu.com","affectedData":[{"vendor":"Canonical","product":"lxd","defaultStatus":"unaffected","collectionURL":"https://github.com/canonical","packageName":"lxd","platforms":["Linux"],"programFiles":["permissions.go"],"repo":"https://github.com/canonical/lxd","versions":[{"version":"6.0","lessThan":"6.10","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@ubuntu.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","baseScore":5.0,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.1,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-26T17:13:30.913771Z","id":"CVE-2026-28385","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@ubuntu.com","type":"Secondary","description":[{"lang":"en","value":"CWE-918"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:canonical:lxd:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndIncluding":"6.9","matchCriteriaId":"96A991F9-74FE-4B09-B5F9-C503F94E1D75"}]}]}],"references":[{"url":"https://github.com/canonical/lxd/pull/18462","source":"security@ubuntu.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/canonical/lxd/security/advisories/GHSA-3gq2-x4qg-p4g6","source":"security@ubuntu.com","tags":["Exploit","Vendor Advisory","Mitigation"]}]}
