{"id":"GHSA-4qqc-mp5f-ccv4","aliases":[],"url":"https://o3.security/vulnerability/GHSA-4qqc-mp5f-ccv4","summary":"Command Injection in bestzip","details":"Versions of `bestzip` prior to 2.1.7 are vulnerable to Command Injection. The package fails to sanitize input rules and passes it directly to an `exec` call on the `zip` function . This may allow attackers to execute arbitrary code in the system as long as the values of `destination` is user-controlled. This only affects users with a native `zip` command available. The following examples demonstrate the issue from the CLI and also programatically:\n- `bestzip test.zip 'sourcefile; mkdir folder'`\n- `zip({ source: 'sourcefile', destination: './test.zip; mkdir folder' })`","published":"2020-09-02T15:05:51Z","modified":"2020-09-02T15:04:08Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"bestzip","fixedVersion":"2.1.7"}],"fix":null,"references":[{"type":"WEB","url":"https://www.npmjs.com/advisories/1554"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2020-09-02T15:04:08Z"}}
