- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2008-03-18 · Updated: 2024-08-07

## Affected

- n/a: version range not reported

## Description

CRLF injection vulnerability in Microsoft Internet Explorer 5 and 6 allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded CRLF (%0D%0A) before the FTP command, which causes the commands to be inserted into an authenticated FTP connection established earlier in the same browser session, as demonstrated using a DELE command, a variant or possibly a regression of CVE-2004-1166. NOTE: a trailing "//" can force Internet Explorer to try to reuse an existing authenticated connection.
