In DBdeployer before version 1.58.2, users unpacking a tarball may use a maliciously packaged tarball that contains symlinks to files external to the target. In such scenario, an attacker could induce dbdeployer to write into a system file, thus altering the computer defenses. For the attack to succeed, the following factors need to contribute: 1) The user is logged in as root. While dbdeployer is usable as root, it was designed to run as unprivileged user. 2) The user has taken a tarball from a non secure source, without testing the checksum. When the tarball is retrieved through dbdeployer, the checksum is compared before attempting to unpack. This has been fixed in version 1.58.2."},{"lang":"es","value":"DBdeployer es una herramienta que despliega servidores de bases de datos MySQL fácilmente. En DBdeployer versiones anteriores a 1.58.2, los usuarios que descomprimen un tarball pueden usar un tarball paquetizado maliciosamente que contiene enlaces simbólicos para archivos externos al objetivo. En tal escenario, un atacante podría inducir a dbdeployer a escribir en un archivo del sistema, alterando así las defensas del ordenador. Para que el ataque tenga éxito, los siguientes factores deben contribuir: 1) El usuario está registrado como root. Si bien dbdeployer puede ser usado como root, fue diseñado para ejecutarse como un usuario sin privilegios. 2) El usuario ha tomado un tarball de una fuente no segura, sin probar el checksum. Cuando el tarball se recupera por medio de dbdeployer, el checksum se compara antes de intentar desempaquetar. Esto se ha abordado en la versión 1.58.2"}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.6,"impactScore":4.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.6,"impactScore":4.0}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:H/Au:N/C:N/I:P/A:P","baseScore":4.0,"accessVector":"NETWORK","accessComplexity":"HIGH","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"PARTIAL","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":4.9,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":true}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-59"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:dbdeployer:dbdeployer:*:*:*:*:*:*:*:*","versionEndExcluding":"1.58.2","matchCriteriaId":"EB0C4463-CC29-4496-B11B-B6203AEC9F6C"}]}]}],"references":[{"url":"https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10","source":"security-advisories@github.com","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Third Party Advisory"]},{"url":"https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
