Prior to 1.1.5 and 1.0.2, there is a nil pointer dereference vulnerability in the Omni Resource Service allows unauthenticated users to cause a server panic and denial of service by sending empty create/update resource requests through the API endpoints. The vulnerability exists in the isSensitiveSpec function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. When a resource is created with an empty Metadata field, the CreateResource function attempts to access resource.Metadata.Version causing a segmentation fault. This vulnerability is fixed in 1.1.5 and 1.0.2."},{"lang":"es","value":"Omni gestiona Kubernetes en metal desnudo, máquinas virtuales o en una nube. Antes de las versiones 1.1.5 y 1.0.2, existe una vulnerabilidad de desreferencia de puntero nulo en el Servicio de Recursos de Omni que permite a usuarios no autenticados causar un pánico del servidor y denegación de servicio enviando solicitudes de creación/actualización de recursos vacías a través de los puntos finales de la API. La vulnerabilidad existe en la función isSensitiveSpec, que llama a grpcomni.CreateResource sin verificar si el campo de metadatos del recurso es nulo. Cuando se crea un recurso con un campo de Metadatos vacío, la función CreateResource intenta acceder a resource.Metadata.Version, causando un fallo de segmentación. Esta vulnerabilidad está corregida en las versiones 1.1.5 y 1.0.2."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"siderolabs","product":"omni","versions":[{"version":">= 1.1.0-beta.0, < 1.1.5","status":"affected"},{"version":"< 1.0.2","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:N/I:N/A:L","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-10-14T14:28:04.746854Z","id":"CVE-2025-59836","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-476"},{"lang":"en","value":"CWE-703"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:siderolabs:omni:*:*:*:*:*:kubernetes:*:*","versionEndExcluding":"1.0.2","matchCriteriaId":"B7B04852-C400-4D56-9C77-EF08063D24DE"},{"vulnerable":true,"criteria":"cpe:2.3:a:siderolabs:omni:*:*:*:*:*:kubernetes:*:*","versionStartIncluding":"1.1.0","versionEndExcluding":"1.1.5","matchCriteriaId":"2102EFDA-BE62-4587-A556-98CF28167D6D"}]}]}],"references":[{"url":"https://github.com/siderolabs/omni/commit/1396083f766a1b0380e9949968d7fc17b7afecaa","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/siderolabs/omni/commit/1fd954af64985a8b3dbf5b11deddbf7cd953f5ae","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/siderolabs/omni/security/advisories/GHSA-4p3p-cr38-v5xp","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]}]}
