CVE-2020-26299 – File System Bounds Escape
https://notcve.org/view.php?id=CVE-2020-26299
ftp-srv is an open-source FTP server designed to be simple yet configurable. In ftp-srv before version 4.4.0 there is a path-traversal vulnerability. Clients of FTP servers utilizing ftp-srv hosted on Windows machines can escape the FTP user's defined root folder using the expected FTP commands, for example, CWD and UPDR. When windows separators exist within the path (`\`), `path.resolve` leaves the upper pointers intact and allows the user to move beyond the root folder defined for that user. We did not take that into account when creating the path resolve function. • https://github.com/autovance/ftp-srv/commit/457b859450a37cba10ff3c431eb4aa67771122e3 https://github.com/autovance/ftp-srv/issues/167 https://github.com/autovance/ftp-srv/issues/225 https://github.com/autovance/ftp-srv/pull/224 https://github.com/autovance/ftp-srv/security/advisories/GHSA-pmw4-jgxx-pcq9 https://www.npmjs.com/package/ftp-srv • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2020-15152 – Server-Side Request Forgery in ftp-srv
https://notcve.org/view.php?id=CVE-2020-15152
ftp-srv is an npm package which is a modern and extensible FTP server designed to be simple yet configurable. In ftp-srv before versions 2.19.6, 3.1.2, and 4.3.4 are vulnerable to Server-Side Request Forgery. The PORT command allows arbitrary IPs which can be used to cause the server to make a connection elsewhere. A possible workaround is blocking the PORT through the configuration. This issue is fixed in version2 2.19.6, 3.1.2, and 4.3.4. • https://github.com/ossf-cve-benchmark/CVE-2020-15152 https://github.com/autovance/ftp-srv/commit/e449e75219d918c400dec65b4b0759f60476abca https://github.com/autovance/ftp-srv/security/advisories/GHSA-jw37-5gqr-cf9j https://www.npmjs.com/package/ftp-srv • CWE-918: Server-Side Request Forgery (SSRF) •
