{"id":"GHSA-m734-r4g6-34f9","summary":"NoSQL Injection in loopback-connector-mongodb","details":"Versions of `loopback-connector-mongodb` before 3.6.0 are vulnerable to NoSQL injection.\n\nMongoDB Connector for LoopBack fails to properly sanitize a filter passed to query the database by allowing the dangerous `$where` property to be passed to the MongoDB Driver. The Driver allows the special `$where` property in a filter to execute JavaScript (client can pass in a malicious script) on the database Driver. This is an [intended feature of MongoDB](https://docs.mongodb.com/manual/core/server-side-javascript/) unless disabled ([instructions here](https://docs.mongodb.com/manual/core/server-side-javascript/#disable-server-side-js)).\n\nA proof of concept malicious query:\n\n```\nGET /POST filter={\"where\": {\"$where\": \"function(){sleep(5000); return this.title.contains('Hello');}\"}}\n```\n\nThe above makes the database sleep for 5 seconds and then returns all “Posts” with the title containing the word `Hello`.\n\n\n\n\n## Recommendation\n\nUpdate to version 3.6.0 or later.","modified":"2021-08-04T20:47:58Z","published":"2019-06-04T19:36:17Z","database_specific":{"cwe_ids":["CWE-89"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2019-06-04T19:35:47Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/strongloop/loopback-connector-mongodb/issues/403"},{"type":"WEB","url":"https://github.com/strongloop/loopback-connector-mongodb/pull/452"},{"type":"WEB","url":"https://github.com/strongloop/loopback-connector-mongodb/commit/ee24cd08b8ccc32711264831c71b1da628df357b"},{"type":"WEB","url":"https://loopback.io/doc/en/lb3/Security-advisory-08-15-2018.html"},{"type":"WEB","url":"https://www.npmjs.com/advisories/696"}],"affected":[{"package":{"name":"loopback-connector-mongodb","ecosystem":"npm","purl":"pkg:npm/loopback-connector-mongodb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.6.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/06/GHSA-m734-r4g6-34f9/GHSA-m734-r4g6-34f9.json"}}],"schema_version":"1.9.0"}
