{"id":"GHSA-qfwq-chf4-jvwg","summary":"karo Metacharacter Handling Remote Command Execution","details":"The karo gem through 2.5.2 for Ruby allows Remote command injection via the host field.\n\nA flaw in `db.rb` is triggered when handling metacharacters. This may allow a remote attacker to execute arbitrary commands.\n\nIn particular lines 76 and 95 (as of `2014-06-01`) pass unsanitized user supplied input to the command line. \n\n```\n73-      host = \"{@configuration[\"user\"]}@{@configuration[\"host\"]}\"\n74-      cmd  = \"ssh #{host} cat {server_db_config_file}\"\n75-\n76:      server_db_config_output = `{cmd}`\n79-\n--\n89- def drop_and_create_local_database(local_db_config)\n90-      command = case local_db_config[\"adapter\"]\n91-      when \"mysql2\"\n93-      when \"postgresql\"\n95-          dropdb -h #{local_db_config[\"host\"]} -U #{local_db_config[\"username\"]} --if-exists #{local_db_config[\"database\"]}\n```\n\nIf this gem is used in the context of a rails application malicious input could lead to remote command injection. As of version 2.5.2 the affected code lines have not changed.","aliases":["CVE-2014-10075"],"modified":"2025-08-15T14:26:31.518025Z","published":"2022-05-14T01:49:44Z","database_specific":{"nvd_published_at":"2018-10-05T06:29:00Z","cwe_ids":["CWE-77"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2023-03-29T20:26:16Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2014-10075"},{"type":"PACKAGE","url":"https://github.com/rahult/karo"},{"type":"WEB","url":"https://github.com/rahult/karo/blob/master/lib/karo/db.rb#L76"},{"type":"WEB","url":"https://github.com/rahult/karo/blob/master/lib/karo/db.rb#L95"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/karo/CVE-2014-10075.yml"},{"type":"WEB","url":"http://www.vapid.dhs.org/advisories/karo-2.3.8.html"},{"type":"WEB","url":"http://www.vapidlabs.com/advisory.php?v=63"}],"affected":[{"package":{"name":"karo","ecosystem":"RubyGems","purl":"pkg:gem/karo"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.5.2"}]}],"versions":["1.0.0","1.1.0","1.2.0","1.2.1","1.3.0","1.4.0","1.5.0","2.0.0","2.1.0","2.1.1","2.1.2","2.1.3","2.2.0","2.2.1","2.3.0","2.3.1","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","2.3.9","2.4.0","2.5.0","2.5.1","2.5.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-qfwq-chf4-jvwg/GHSA-qfwq-chf4-jvwg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
