{"id":"CVE-2020-26277","aliases":["GHSA-47wr-426j-fr82","GO-2022-0787"],"url":"https://o3.security/vulnerability/CVE-2020-26277","summary":"Symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations in dbdeployer","details":"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.","published":"2020-12-21T22:15:13.317Z","modified":"2026-07-09T01:25:30.490545Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/datacharmer/dbdeployer","fixedVersion":"1.58.2"}],"fix":{"url":"https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10","label":"datacharmer/dbdeployer@548e256"},"references":[{"type":"ADVISORY","url":"https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82"},{"type":"FIX","url":"https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:25:30.490545Z"}}
