{"id":"CVE-2013-7371","aliases":[],"url":"https://o3.security/vulnerability/CVE-2013-7371","summary":"Node Connect Reflected Cross-Site Scripting in Sencha Labs Connect middleware","details":"node-connect before 2.8.2 has cross site scripting in Sencha Labs Connect middleware (vulnerability due to incomplete fix for CVE-2013-7370)\n\n### Overview\nConnect is a stack of middleware that is executed in order in each request.\n\nThe \"methodOverride\" middleware allows the http post to override the method of the request with the value of the \"_method\" post key or with the header \"x-http-method-override\".\n\nBecause the user post input was not checked, req.method could contain any kind of value. Because the req.method did not match any common method VERB, connect answered with a 404 page containing the \"Cannot `[method]` `[url]`\" content. The method was not properly encoded for output in the browser.\n\n\n### Example:\n```\n~ curl \"localhost:3000\" -d \"_method=<script src=http://nodesecurity.io/xss.js></script>\"\nCannot <SCRIPT SRC=HTTP://NODESECURITY.IO/XSS.JS></SCRIPT> /\n```\n\n### Recommendation\n\nUpdate to the newest version of Connect or disable methodOverride. It is not possible to avoid the vulnerability if you have enabled this middleware in the top of your stack.\n\n### Credit:\nSergio Arcos","published":"2022-05-05T00:29:11Z","modified":"2023-11-08T03:57:28.875899Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"connect","fixedVersion":"2.8.2"}],"fix":{"url":"https://github.com/senchalabs/connect/commit/126187c4e12162e231b87350740045e5bb06e93a","label":"senchalabs/connect@126187c"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2013-7371"},{"type":"WEB","url":"https://github.com/senchalabs/connect/issues/831"},{"type":"WEB","url":"https://github.com/senchalabs/connect/commit/126187c4e12162e231b87350740045e5bb06e93a"},{"type":"WEB","url":"https://github.com/senchalabs/connect/commit/277e5aad6a95d00f55571a9a0e11f2fa190d8135"},{"type":"WEB","url":"https://access.redhat.com/security/cve/cve-2013-7371"},{"type":"WEB","url":"https://exchange.xforce.ibmcloud.com/vulnerabilities/92710"},{"type":"PACKAGE","url":"https://github.com/senchalabs/connect"},{"type":"WEB","url":"https://nodesecurity.io/advisories/methodOverride_Middleware_Reflected_Cross-Site_Scripting"},{"type":"WEB","url":"https://security-tracker.debian.org/tracker/CVE-2013-7371"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2014/04/21/2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2014/05/13/1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T03:57:28.875899Z"}}
