CVE-2011-3639 1 Apache 10 Http Server, Http Server2.0a1, Http Server2.0a2 and 7 more 2025-04-11 4.3 MEDIUM N/A
The mod_proxy module in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x before 2.2.18, when the Revision 1179239 patch is in place, does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers by using the HTTP/0.9 protocol with a malformed URI containing an initial @ (at sign) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-3368.
CVE-2012-0053 5 Apache, Debian, Opensuse and 2 more 12 Http Server, Debian Linux, Opensuse and 9 more 2025-04-11 4.3 MEDIUM N/A
protocol.c in the Apache HTTP Server 2.2.x through 2.2.21 does not properly restrict header information during construction of Bad Request (aka 400) error documents, which allows remote attackers to obtain the values of HTTPOnly cookies via vectors involving a (1) long or (2) malformed header in conjunction with crafted web script.
CVE-2012-4557 1 Apache 1 Http Server 2025-04-11 5.0 MEDIUM N/A
The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 places a worker node into an error state upon detection of a long request-processing time, which allows remote attackers to cause a denial of service (worker consumption) via an expensive request.
CVE-2010-1452 1 Apache 1 Http Server 2025-04-11 5.0 MEDIUM N/A
The (1) mod_cache and (2) mod_dav modules in the Apache HTTP Server 2.2.x before 2.2.16 allow remote attackers to cause a denial of service (process crash) via a request that lacks a path.
CVE-2010-0425 2 Apache, Microsoft 2 Http Server, Windows 2025-04-11 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-2011-1176 3 Apache, Debian, Mpm-itk Project 3 Http Server, Debian Linux, Mpm-itk 2025-04-11 4.3 MEDIUM N/A
The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk Multi-Processing Module 2.2.11-01 and 2.2.11-02 for the Apache HTTP Server does not properly handle certain configuration sections that specify NiceValue but not AssignUserID, which might allow remote attackers to gain privileges by leveraging the root uid and root gid of an mpm-itk process.
CVE-2011-1928 1 Apache 2 Apr-util, Http Server 2025-04-11 4.3 MEDIUM N/A
The fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library 1.4.3 and 1.4.4, and the Apache HTTP Server 2.2.18, allows remote attackers to cause a denial of service (infinite loop) via a URI that does not match unspecified types of wildcard patterns, as demonstrated by attacks against mod_autoindex in httpd when a /*/WEB-INF/ configuration pattern is used. NOTE: this issue exists because of an incorrect fix for CVE-2011-0419.
CVE-2011-3192 1 Apache 1 Http Server 2025-04-11 7.8 HIGH N/A
The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086.
CVE-2012-0031 5 Apache, Debian, Opensuse and 2 more 13 Http Server, Debian Linux, Opensuse and 10 more 2025-04-11 4.6 MEDIUM N/A
scoreboard.c in the Apache HTTP Server 2.2.21 and earlier might allow local users to cause a denial of service (daemon crash during shutdown) or possibly have unspecified other impact by modifying a certain type field within a scoreboard shared memory segment, leading to an invalid call to the free function.
CVE-2012-3526 2 Apache, Thomas Eibner 2 Http Server, Mod Rpaf 2025-04-11 5.0 MEDIUM N/A
The reverse proxy add forward module (mod_rpaf) 0.5 and 0.6 for the Apache HTTP Server allows remote attackers to cause a denial of service (server or application crash) via multiple X-Forwarded-For headers in a request.
CVE-2013-5697 2 Apache, Simone Tellini 2 Http Server, Mod Accounting 2025-04-11 7.5 HIGH N/A
SQL injection vulnerability in mod_accounting.c in the mod_accounting module 0.5 and earlier for Apache allows remote attackers to execute arbitrary SQL commands via a Host header.
CVE-2003-1580 1 Apache 1 Http Server 2025-04-11 4.3 MEDIUM N/A
The Apache HTTP Server 2.0.44, when DNS resolution is enabled for client IP addresses, uses a logging format that does not identify whether a dotted quad represents an unresolved IP address, which allows remote attackers to spoof IP addresses via crafted DNS responses containing numerical top-level domains, as demonstrated by a forged 123.123.123.123 domain name, related to an "Inverse Lookup Log Corruption (ILLC)" issue.
CVE-2009-1956 2 Apache, Canonical 3 Apr-util, Http Server, Ubuntu Linux 2025-04-09 6.4 MEDIUM N/A
Off-by-one error in the apr_brigade_vprintf function in Apache APR-util before 1.3.5 on big-endian platforms allows remote attackers to obtain sensitive information or cause a denial of service (application crash) via crafted input.
CVE-2007-1862 1 Apache 1 Http Server 2025-04-09 5.0 MEDIUM N/A
The recall_headers function in mod_mem_cache in Apache 2.2.4 does not properly copy all levels of header data, which can cause Apache to return HTTP headers containing previously used data, which could be used by remote attackers to obtain potentially sensitive information.
CVE-2007-1863 2 Apache, Apple 2 Http Server, Mac Os X Server 2025-04-09 5.0 MEDIUM N/A
cache_util.c in the mod_cache module in Apache HTTP Server (httpd), when caching is enabled and a threaded Multi-Processing Module (MPM) is used, allows remote attackers to cause a denial of service (child processing handler crash) via a request with the (1) s-maxage, (2) max-age, (3) min-fresh, or (4) max-stale Cache-Control headers without a value.
CVE-2007-1741 1 Apache 1 Http Server 2025-04-09 6.2 MEDIUM N/A
Multiple race conditions in suexec in Apache HTTP Server (httpd) 2.2.3 between directory and file validation, and their usage, allow local users to gain privileges and execute arbitrary code by renaming directories or performing symlink attacks. NOTE: the researcher, who is reliable, claims that the vendor disputes the issue because "the attacks described rely on an insecure server configuration" in which the user "has write access to the document root."
CVE-2008-0456 1 Apache 1 Http Server 2025-04-09 2.6 LOW N/A
CRLF injection vulnerability in the mod_negotiation module in the Apache HTTP Server 2.2.6 and earlier in the 2.2.x series, 2.0.61 and earlier in the 2.0.x series, and 1.3.39 and earlier in the 1.3.x series allows remote authenticated users to inject arbitrary HTTP headers and conduct HTTP response splitting attacks by uploading a file with a multi-line name containing HTTP header sequences and a file extension, which leads to injection within a (1) "406 Not Acceptable" or (2) "300 Multiple Choices" HTTP response when the extension is omitted in a request for the file.
CVE-2007-3303 1 Apache 1 Http Server 2025-04-09 4.9 MEDIUM N/A
Apache httpd 2.0.59 and 2.2.4, with the Prefork MPM module, allows local users to cause a denial of service via certain code sequences executed in a worker process that (1) stop request processing by killing all worker processes and preventing creation of replacements or (2) hang the system by forcing the master process to fork an arbitrarily large number of worker processes. NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.
CVE-2009-1191 2 Apache, Canonical 2 Http Server, Ubuntu Linux 2025-04-09 5.0 MEDIUM N/A
mod_proxy_ajp.c in the mod_proxy_ajp module in the Apache HTTP Server 2.2.11 allows remote attackers to obtain sensitive response data, intended for a client that sent an earlier POST request with no request body, via an HTTP request.
CVE-2007-6388 1 Apache 1 Http Server 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in mod_status in the Apache HTTP Server 2.2.0 through 2.2.6, 2.0.35 through 2.0.61, and 1.3.2 through 1.3.39, when the server-status page is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
