{"id":"CVE-2020-26277","state":"PUBLISHED","title":"Arbitrary read/write in DBdeployer","description":"DBdeployer is a tool that deploys MySQL database servers easily. 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.","publishedAt":"2020-12-21T21:15:14.000Z","updatedAt":"2024-08-04T15:56:03.912Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["datacharmer dbdeployer"],"affected":[{"vendor":"datacharmer","product":"dbdeployer","versions":[{"version":"< 1.58.2","status":"affected"}]}],"references":["https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82","https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10"],"weaknesses":["CWE-59"],"ingestedAt":"2026-10-29T19:47:08.370Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/26xxx/CVE-2020-26277.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-26277","state":"PUBLISHED","datePublished":"2020-12-21T21:15:14.000Z","dateUpdated":"2024-08-04T15:56:03.912Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2020-10-01T00:00:00.000Z"},"containers":{"cna":{"title":"Arbitrary read/write in DBdeployer","descriptions":[{"lang":"en","value":"DBdeployer is a tool that deploys MySQL database servers easily.
