(This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass."},{"lang":"es","value":"dbus anterior a versión 1.10.28, versión 1.12.x anterior a 1.12.16, y versión 1.13.x anterior a 1.13.12, como es usado en DBusServer en Canonst Upstart en Ubuntu versión 14.04 (y en algunos usos menos comunes de demonio dbus), permite suplantación de identidad de cookie debido al manejo inapropiado de enlaces simbólicos (symlink) en la implementación de referencia de DBUS_COOKIE_SHA1 en la biblioteca libdbus. (Esto solo afecta el mecanismo de autenticación DBUS_COOKIE_SHA1). Un cliente malicioso con acceso de escritura a su propio directorio de inicio podría manipular un enlace simbólico ~/.dbus-keyrings para hacer que un DBusServer con un uid diferente lea y escriba en ubicaciones no deseadas. En el peor de los casos, esto podría hacer que DBusServer reutilice una cookie que es conocida por el cliente malicioso, y tratar esa cookie como evidencia de que una conexión de cliente subsiguiente provino de un uid elegido por el atacante, lo que permite la omisión de autenticación."}],"affected":[{"source":"cve@mitre.org","affectedData":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":5.2}],"cvssMetricV30":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":5.2}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:P/I:P/A:N","baseScore":3.6,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"LOW","exploitabilityScore":3.9,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-02-13T19:57:51.850522Z","id":"CVE-2019-12749","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA
