{"cve":"CVE-2020-26277","nvd":{"published":"2020-12-21T22:15:13.317","modified":"2026-06-17T03:07:58.930","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N","score":6.1},"cwes":["CWE-59"],"references":["https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10","https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82","https://github.com/datacharmer/dbdeployer/commit/548e256c1de2f99746e861454e7714ec6bc9bb10","https://github.com/datacharmer/dbdeployer/security/advisories/GHSA-47wr-426j-fr82"],"products":["dbdeployer:dbdeployer"],"source":"nvd","synced_at":"2026-10-19T21:12:09.559580076+00:00"},"epss":{"cve":"CVE-2020-26277","score":0.01201,"percentile":0.68207,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-47wr-426j-fr82","url":"https://osv.dev/vulnerability/GHSA-47wr-426j-fr82","summary":"Symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations in dbdeployer","modified":"2026-07-08T05:59:50.632396529Z","packages":[{"ecosystem":"Go","name":"github.com/datacharmer/dbdeployer","purl":"pkg:golang/github.com/datacharmer/dbdeployer","ranges":["<1.58.2"],"fixed":["1.58.2"]}]},{"id":"GO-2022-0787","url":"https://osv.dev/vulnerability/GO-2022-0787","summary":"Symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations in dbdeployer in github.com/datacharmer/dbdeployer","modified":"2026-03-03T04:50:53.913231Z","packages":[{"ecosystem":"Go","name":"github.com/datacharmer/dbdeployer","purl":"pkg:golang/github.com/datacharmer/dbdeployer","ranges":["<1.58.2"],"fixed":["1.58.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
