CVE-2007-3947 1 Lighttpd 1 Lighttpd 2025-04-09 N/A
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-2007-3948 1 Lighttpd 1 Lighttpd 2025-04-09 N/A
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-2007-3949 1 Lighttpd 1 Lighttpd 2025-04-09 N/A
mod_access.c in lighttpd 1.4.15 ignores trailing / (slash) characters in the URL, which allows remote attackers to bypass url.access-deny settings.
CVE-2007-3950 1 Lighttpd 1 Lighttpd 2025-04-09 N/A
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 modules.
CVE-2007-4727 1 Lighttpd 1 Lighttpd 2025-04-09 N/A
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-2005-0453 1 Lighttpd 1 Lighttpd 2025-04-03 N/A
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.
CVE-2006-0814 1 Lighttpd 1 Lighttpd 2025-04-03 N/A
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-2006-0760 1 Lighttpd 1 Lighttpd 2025-04-03 N/A
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 invokes the PHP interpreter only for ".php" names.
CVE-2018-25103 1 Lighttpd 1 Lighttpd 2025-02-13 5.3 Medium
There exists use-after-free vulnerabilities in lighttpd <= 1.4.50 request parsing which might read from invalid pointers to memory used in the same request, not from other requests.
CVE-2022-41556 2 Fedoraproject, Lighttpd 2 Fedora, Lighttpd 2024-11-21 7.5 High
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 mod_fastcgi is, for example, affected. This is fixed in 1.4.67.
CVE-2022-37797 2 Debian, Lighttpd 2 Debian Linux, Lighttpd 2024-11-21 7.5 High
In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could be used by an external attacker to cause denial of service condition.
CVE-2022-30780 1 Lighttpd 1 Lighttpd 2024-11-21 7.5 High
Lighttpd 1.4.56 through 1.4.58 allows a remote attacker to cause a denial of service (CPU consumption from stuck connections) because connection_read_header_more in connections.c has a typo that disrupts use of multiple read operations on large headers.
CVE-2022-22707 2 Debian, Lighttpd 2 Debian Linux, Lighttpd 2024-11-21 5.9 Medium
In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system.
CVE-2019-11072 1 Lighttpd 1 Lighttpd 2024-11-21 N/A
lighttpd before 1.4.54 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a malicious HTTP GET request, as demonstrated by mishandling of /%2F? in burl_normalize_2F_to_slash_fix in burl.c. NOTE: The developer states "The feature which can be abused to cause the crash is a new feature in lighttpd 1.4.50, and is not enabled by default. It must be explicitly configured in the config file (e.g. lighttpd.conf). Certain input will trigger an abort() in lighttpd when that feature is enabled. lighttpd detects the underflow or realloc() will fail (in both 32-bit and 64-bit executables), also detected in lighttpd. Either triggers an explicit abort() by lighttpd. This is not exploitable beyond triggering the explicit abort() with subsequent application exit.
CVE-2018-19052 4 Debian, Lighttpd, Opensuse and 1 more 5 Debian Linux, Lighttpd, Backports Sle and 2 more 2024-11-21 7.5 High
An issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.
