| CVE-2014-2323 | Cri | 0.71 | 9.8 | 0.90 | Mar 14, 2014 | SQL injection vulnerability in mod_mysql_vhost.c in lighttpd before 1.4.35 allows remote attackers to execute arbitrary SQL commands via the host name, related to request_check_hostname. | |
| CVE-2015-3200 | Hig | 0.50 | 7.5 | 0.20 | Jun 9, 2015 | mod_auth in lighttpd before 1.4.36 allows remote attackers to inject arbitrary log entries via a basic HTTP authentication string without a colon character, as demonstrated by a string containing a NULL and new line character. | |
| CVE-2013-4508 | Hig | 0.49 | 7.5 | 0.01 | Nov 8, 2013 | lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network. | |
| CVE-2014-2324 | 0.06 | — | 0.72 | Mar 14, 2014 | Multiple directory traversal vulnerabilities in (1) mod_evhost and (2) mod_simple_vhost in lighttpd before 1.4.35 allow remote attackers to read arbitrary files via a .. (dot dot) in the host name, related to request_check_hostname. | ||
| CVE-2012-5533 | 0.06 | — | 0.38 | Nov 24, 2012 | The http_request_split_value function in request.c in lighttpd before 1.4.32 allows remote attackers to cause a denial of service (infinite loop) via a request with a header containing an empty token, as demonstrated using the "Connection: TE,,Keep-Alive" header. | ||
| CVE-2008-1270 | 0.04 | — | 0.09 | Mar 10, 2008 | mod_userdir in lighttpd 1.4.18 and earlier, when userdir.path is not set, uses a default of $HOME, which might allow remote attackers to read arbitrary files, as demonstrated by accessing the ~nobody directory. | ||
| CVE-2007-3947 | 0.04 | — | 0.16 | Jul 24, 2007 | request.c in lighttpd 1.4.15 allows remote attackers to cause a denial of service (daemon crash) by sending an HTTP request with duplicate headers, as demonstrated by a request containing two Location header lines, which results in a segmentation fault. | ||
| CVE-2011-4362 | 0.03 | — | 0.04 | Dec 24, 2011 | Integer signedness error in the base64_decode function in the HTTP authentication functionality (http_auth.c) in lighttpd 1.4 before 1.4.30 and 1.5 before SVN revision 2806 allows remote attackers to cause a denial of service (segmentation fault) via crafted base64 input that triggers an out-of-bounds read with a negative index. | ||
| CVE-2010-0295 | 0.03 | — | 0.06 | Feb 3, 2010 | lighttpd before 1.4.26, and 1.5.x, allocates a buffer for each read operation that occurs for a request, which allows remote attackers to cause a denial of service (memory consumption) by breaking a request into small pieces that are sent at a slow rate. | ||
| CVE-2013-4560 | 0.01 | — | 0.07 | 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-2013-4559 | 0.01 | — | 0.10 | Nov 20, 2013 | lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached. | ||
| CVE-2007-4727 | 0.01 | — | 0.19 | Sep 12, 2007 | Buffer overflow in the fcgi_env_add function in mod_proxy_backend_fastcgi.c in the mod_fastcgi extension in lighttpd before 1.4.18 allows remote attackers to overwrite arbitrary CGI variables and execute arbitrary code via an HTTP request with a long content length, as demonstrated by overwriting the SCRIPT_FILENAME variable, aka a "header overflow." | ||
| CVE-2025-12642 | 0.00 | — | 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 backend logic that trusts request headers * Execute HTTP Request Smuggling attacks under some conditions This issue affects lighttpd1.4.80 | ||
| CVE-2013-1427 | 0.00 | — | 0.00 | Mar 21, 2013 | The configuration file for the FastCGI PHP support for lighttpd before 1.4.28 on Debian GNU/Linux creates a socket file with a predictable name in /tmp, which allows local users to hijack the PHP control socket and perform unauthorized actions such as forcing the use of a different version of PHP via a symlink attack or a race condition. | ||
| CVE-2008-4360 | 0.00 | — | 0.01 | Oct 3, 2008 | mod_userdir in lighttpd before 1.4.20, when a case-insensitive operating system or filesystem is used, performs case-sensitive comparisons on filename components in configuration options, which might allow remote attackers to bypass intended access restrictions, as demonstrated by a request for a .PHP file when there is a configuration rule for .php files. | ||
| CVE-2008-4359 | 0.00 | — | 0.00 | 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 | — | 0.03 | 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 | — | 0.04 | 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 causes all active SSL connections to be lost. | ||
| CVE-2008-1111 | 0.00 | — | 0.01 | 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 | — | 0.05 | 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. |
