| CVE-2006-0814 | 0.01 | — | 0.11 | Mar 6, 2006 | response.c in Lighttpd 1.4.10 and possibly previous versions, when run on Windows, allows remote attackers to read arbitrary source code via requests that contain trailing (1) "." (dot) and (2) space characters, which are ignored by Windows, as demonstrated by PHP files. | |||
| CVE-2025-12642 | Cri | 0.00 | 9.1 | 0.00 | Nov 3, 2025 | lighttpd1.4.80 incorrectly merged trailer fields into headers after http request parsing. This behavior can be exploited to conduct HTTP Header Smuggling attacks. Successful exploitation may allow an attacker to: * Bypass access control rules * Inject unsafe input into… | ||
| CVE-2022-41556 | Hig | 0.00 | 7.5 | 0.03 | Oct 6, 2022 | A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of… | ||
| CVE-2013-4560 | 0.00 | — | 0.05 | Nov 20, 2013 | Use-after-free vulnerability in lighttpd before 1.4.33 allows remote attackers to cause a denial of service (segmentation fault and crash) via unspecified vectors that trigger FAMMonitorDirectory failures. | |||

| CVE-2008-4359 | 0.00 | — | 0.04 | Oct 3, 2008 | lighttpd before 1.4.20 compares URIs to patterns in the (1) url.redirect and (2) url.rewrite configuration settings before performing URL decoding, which might allow remote attackers to bypass intended access restrictions, and obtain sensitive information or possibly modify data. | |||
| CVE-2008-4298 | 0.00 | — | 0.04 | Sep 27, 2008 | Memory leak in the http_request_parse function in request.c in lighttpd before 1.4.20 allows remote attackers to cause a denial of service (memory consumption) via a large number of requests with duplicate request headers. | |||
| CVE-2008-1531 | 0.00 | — | 0.03 | Mar 27, 2008 | The connection_state_machine function (connections.c) in lighttpd 1.4.19 and earlier, and 1.5.x before 1.5.0, allows remote attackers to cause a denial of service (active SSL connection loss) by triggering an SSL error, such as disconnecting before a download has finished, which… | |||
| CVE-2008-1111 | 0.00 | — | 0.02 | Mar 4, 2008 | mod_cgi in lighttpd 1.4.18 sends the source code of CGI scripts instead of a 500 error when a fork failure occurs, which might allow remote attackers to obtain sensitive information. | |||
| CVE-2008-0983 | 0.00 | — | 0.02 | Feb 26, 2008 | lighttpd 1.4.18, and possibly other versions before 1.5.0, does not properly calculate the size of a file descriptor array, which allows remote attackers to cause a denial of service (crash) via a large number of connections, which triggers an out-of-bounds access. | |||
| CVE-2007-3950 | 0.00 | — | 0.03 | Jul 24, 2007 | lighttpd 1.4.15, when run on 32 bit platforms, allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving the use of incompatible format specifiers in certain debugging messages in the (1) mod_scgi, (2) mod_fastcgi, and (3) mod_webdav… | |||

| CVE-2007-3948 | 0.00 | — | 0.03 | Jul 24, 2007 | connections.c in lighttpd before 1.4.16 might accept more connections than the configured maximum, which allows remote attackers to cause a denial of service (failed assertion) via a large number of connection attempts. | |||
| CVE-2007-1869 | 0.00 | — | 0.03 | Apr 18, 2007 | lighttpd 1.4.12 and 1.4.13 allows remote attackers to cause a denial of service (cpu and resource consumption) by disconnecting while lighttpd is parsing CRLF sequences, which triggers an infinite loop and file descriptor consumption. | |||
| CVE-2007-1870 | 0.00 | — | 0.03 | Apr 18, 2007 | lighttpd before 1.4.14 allows attackers to cause a denial of service (crash) via a request to a file whose mtime is 0, which results in a NULL pointer dereference. | |||
| CVE-2006-0760 | 0.00 | — | 0.02 | Feb 18, 2006 | LightTPD 1.4.8 and earlier, when the web root is on a case-insensitive filesystem, allows remote attackers to bypass URL checks and obtain sensitive information via file extensions with unexpected capitalization, as demonstrated by a request for index.PHP when the configuration… | |||
| CVE-2005-0453 | 0.00 | — | 0.02 | Feb 16, 2005 | The buffer_urldecode function in Lighttpd 1.3.7 and earlier does not properly handle control characters, which allows remote attackers to obtain the source code for CGI and FastCGI scripts via a URL with a %00 (null) character after the file extension. |
