CVE-2002-0392 2 Apache, Debian 2 Http Server, Debian Linux 2021-07-15 7.5 HIGH N/A
Apache 1.3 through 1.3.24, and Apache 2.0 through 2.0.36, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a chunk-encoded HTTP request that causes Apache to use an incorrect size.
CVE-2003-0083 1 Apache 1 Http Server 2021-07-15 5.0 MEDIUM N/A
Apache 1.3 before 1.3.25 and Apache 2.0 before version 2.0.46 does not filter terminal escape sequences from its access logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences, a different vulnerability than CVE-2003-0020.
CVE-2001-1534 1 Apache 1 Http Server 2021-07-15 2.1 LOW N/A
mod_usertrack in Apache 1.3.11 through 1.3.20 generates session ID's using predictable information including host IP address, system time and server process ID, which allows local users to obtain session ID's and bypass authentication when these session ID's are used for authentication.
CVE-2003-0132 1 Apache 1 Http Server 2021-07-15 5.0 MEDIUM N/A
A memory leak in Apache 2.0 through 2.0.44 allows remote attackers to cause a denial of service (memory consumption) via large chunks of linefeed characters, which causes Apache to allocate 80 bytes for each linefeed.
CVE-2019-10097 2 Apache, Oracle 8 Http Server, Communications Element Manager, Communications Session Report Manager and 5 more 2021-07-07 6.0 MEDIUM 7.2 HIGH
In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients.
CVE-2018-17189 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2021-07-06 5.0 MEDIUM 5.3 MEDIUM
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.
CVE-2001-0925 2 Apache, Debian 2 Http Server, Debian Linux 2021-07-06 5.0 MEDIUM N/A
The default installation of Apache before 1.3.19 allows remote attackers to list directories instead of the multiview index.html file via an HTTP request for a path that contains many / (slash) characters, which causes the path to be mishandled by (1) mod_negotiation, (2) mod_dir, or (3) mod_autoindex.
CVE-2019-10098 1 Apache 1 Http Server 2021-06-14 5.8 MEDIUM 6.1 MEDIUM
In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL.
CVE-2003-0192 1 Apache 1 Http Server 2021-06-06 6.4 MEDIUM N/A
Apache 2 before 2.0.47, and certain versions of mod_ssl for Apache 1.3, do not properly handle "certain sequences of per-directory renegotiations and the SSLCipherSuite directive being used to upgrade from a weak ciphersuite to a strong one," which could cause Apache to use the weak ciphersuite.
CVE-2010-0425 2 Apache, Microsoft 2 Http Server, Windows 2021-06-06 10.0 HIGH N/A
modules/arch/win32/mod_isapi.c in mod_isapi in the Apache HTTP Server 2.0.37 through 2.0.63, 2.2.0 through 2.2.14, and 2.3.x before 2.3.7, when running on Windows, does not ensure that request processing is complete before calling isapi_unload for an ISAPI .dll module, which allows remote attackers to execute arbitrary code via unspecified vectors related to a crafted request, a reset packet, and "orphaned callback pointers."
CVE-2003-0189 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.
CVE-2001-1342 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
Apache before 1.3.20 on Windows and OS/2 systems allows remote attackers to cause a denial of service (GPF) via an HTTP request for a URI that contains a large number of / (slash) or other characters, which causes certain functions to dereference a null pointer.
CVE-2010-0010 1 Apache 1 Http Server 2021-06-06 6.8 MEDIUM N/A
Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow.
CVE-2003-0245 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
Vulnerability in the apr_psprintf function in the Apache Portable Runtime (APR) library for Apache 2.0.37 through 2.0.45 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long strings, as demonstrated using XML objects to mod_dav, and possibly other vectors.
CVE-2003-0134 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
Unknown vulnerability in filestat.c for Apache running on OS2, versions 2.0 through 2.0.45, allows unknown attackers to cause a denial of service via requests related to device names.
CVE-2014-0117 2 Apache, Apple 2 Http Server, Mac Os X 2021-06-06 4.3 MEDIUM N/A
The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header.
CVE-2019-0196 3 Apache, Canonical, Debian 3 Http Server, Ubuntu Linux, Debian Linux 2021-06-06 5.0 MEDIUM 5.3 MEDIUM
A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly.
CVE-2017-15715 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2021-06-06 6.8 MEDIUM 8.1 HIGH
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.
CVE-2017-9798 2 Apache, Debian 2 Http Server, Debian Linux 2021-06-06 5.0 MEDIUM 7.5 HIGH
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
CVE-2003-0020 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM N/A
Apache does not filter terminal escape sequences from its error logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences.
