| CVE-2016-4971 | Hig | 0.66 | 8.8 | 0.75 | Jun 30, 2016 | GNU wget before 1.18 allows remote servers to write to arbitrary files by redirecting a request from HTTP to a crafted FTP resource. | |
| CVE-2017-13089 | Hig | 0.63 | 8.8 | 0.76 | Oct 27, 2017 | The http.c:skip_short_body() function is called in some circumstances, such as when processing redirects. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. | |
| CVE-2017-13090 | Hig | 0.58 | 8.8 | 0.09 | Oct 27, 2017 | The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer. | |
| CVE-2017-6508 | Med | 0.40 | 6.1 | 0.00 | Mar 7, 2017 | CRLF injection vulnerability in the url_parse function in url.c in Wget through 1.19.1 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in the host subcomponent of a URL. | |
| CVE-2014-4877 | 0.09 | — | 0.74 | Oct 29, 2014 | Absolute path traversal vulnerability in GNU Wget before 1.16, when recursion is enabled, allows remote FTP servers to write to arbitrary files, and consequently execute arbitrary code, via a LIST response that references the same filename within two entries, one of which indicates that the filename is for a symlink. | ||
| CVE-2004-1488 | 0.04 | — | 0.13 | Apr 27, 2005 | wget 1.8.x and 1.9.x does not filter or quote control characters when displaying HTTP responses to the terminal, which may allow remote malicious web servers to inject terminal escape sequences and execute arbitrary code. | ||
| CVE-2006-6719 | 0.03 | — | 0.04 | Dec 23, 2006 | The ftp_syst function in ftp-basic.c in Free Software Foundation (FSF) GNU wget 1.10.2 allows remote attackers to cause a denial of service (application crash) via a malicious FTP server with a large number of blank 220 responses to the SYST command. | ||
| CVE-2004-2014 | 0.03 | — | 0.00 | Dec 31, 2004 | Wget 1.9 and 1.9.1 allows local users to overwrite arbitrary files via a symlink attack on the name of the file being downloaded. | ||
| CVE-2010-2252 | 0.00 | — | 0.05 | Jul 6, 2010 | GNU Wget 1.12 and earlier uses a server-provided filename instead of the original URL to determine the destination filename of a download, which allows remote servers to create or overwrite arbitrary files via a 3xx redirect to a URL with a .wgetrc filename followed by a 3xx redirect to a URL with a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory. | ||
| CVE-2009-3490 | 0.00 | — | 0.02 | Sep 30, 2009 | GNU Wget before 1.12 does not properly handle a '\0' character in a domain name in the Common Name field of an X.509 certificate, which allows man-in-the-middle remote attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | ||
| CVE-2004-1487 | 0.00 | — | 0.01 | Apr 27, 2005 | wget 1.8.x and 1.9.x allows a remote malicious web server to overwrite certain files via a redirection URL containing a ".." that resolves to the IP address of the malicious server, which bypasses wget's filtering for ".." sequences. | ||
| CVE-2002-1344 | 0.00 | — | 0.01 | Dec 18, 2002 | Directory traversal vulnerability in wget before 1.8.2-4 allows a remote FTP server to create or overwrite files as the wget user via filenames containing (1) /absolute/path or (2) .. (dot dot) sequences. | ||
| CVE-1999-0402 | 0.00 | — | 0.00 | Jan 2, 1999 | wget 1.5.3 follows symlinks to change permissions of the target file instead of the symlink itself. |
