The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625.
CVE-2009-2299 2 Apache, Hyperguard Web Application Firewall Project 2 Http Server, Hyperguard Web Application Firewall 2025-04-09 5.0 MEDIUM N/A
The Artofdefence Hyperguard Web Application Firewall (WAF) module before 2.5.5-11635, 3.0 before 3.0.3-11636, and 3.1 before 3.1.1-11637, a module for the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via an HTTP request with a large Content-Length value but no POST data.
CVE-2007-3304 4 Apache, Canonical, Fedoraproject and 1 more 6 Http Server, Ubuntu Linux, Fedora and 3 more 2025-04-09 4.7 MEDIUM N/A
Apache httpd 1.3.37, 2.0.59, and 2.2.4 with the Prefork MPM module, allows local users to cause a denial of service by modifying the worker_score and process_score arrays to reference an arbitrary process ID, which is sent a SIGUSR1 signal from the master process, aka "SIGUSR1 killer."
CVE-2009-0023 1 Apache 2 Apr-util, Http Server 2025-04-09 4.3 MEDIUM N/A
The apr_strmatch_precompile function in strmatch/apr_strmatch.c in Apache APR-util before 1.3.5 allows remote attackers to cause a denial of service (daemon crash) via crafted input involving (1) a .htaccess file used with the Apache HTTP Server, (2) the SVNMasterURI directive in the mod_dav_svn module in the Apache HTTP Server, (3) the mod_apreq2 module for the Apache HTTP Server, or (4) an application that uses the libapreq2 library, which triggers a heap-based buffer underflow.
CVE-2008-0005 3 Apache, Canonical, Fedoraproject 3 Http Server, Ubuntu Linux, Fedora 2025-04-09 4.3 MEDIUM N/A
mod_proxy_ftp in Apache 2.2.x before 2.2.7-dev, 2.0.x before 2.0.62-dev, and 1.3.x before 1.3.40-dev does not define a charset, which allows remote attackers to conduct cross-site scripting (XSS) attacks using UTF-7 encoding.
CVE-2008-2168 1 Apache 1 Http Server 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Apache 2.2.6 and earlier allows remote attackers to inject arbitrary web script or HTML via UTF-7 encoded URLs that are not properly handled when displaying the 403 Forbidden error page.
CVE-2008-0456 2 Apache, Redhat 4 Http Server, Enterprise Linux Desktop, Enterprise Linux Server and 1 more 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-2007-0086 1 Apache 1 Http Server 2025-04-09 7.8 HIGH N/A
The Apache HTTP Server, when accessed through a TCP connection with a large window size, allows remote attackers to cause a denial of service (network bandwidth consumption) via a Range header that specifies multiple copies of the same fragment. NOTE: the severity of this issue has been disputed by third parties, who state that the large window size required by the attack is not normally supported or configured by the server, or that a DDoS-style attack would accomplish the same goal
CVE-2007-1742 1 Apache 1 Http Server 2025-04-09 3.7 LOW N/A
suexec in Apache HTTP Server (httpd) 2.2.3 uses a partial comparison for verifying whether the current directory is within the document root, which might allow local users to perform unauthorized operations on incorrect directories, as demonstrated using "html_backup" and "htmleditor" under an "html" directory. 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-2006-4154 1 Apache 1 Http Server 2025-04-09 6.8 MEDIUM N/A
Format string vulnerability in the mod_tcl module 1.0 for Apache 2.x allows context-dependent attackers to execute arbitrary code via format string specifiers that are not properly handled in a set_var function call in (1) tcl_cmds.c and (2) tcl_core.c.
CVE-2007-0450 1 Apache 2 Http Server, Tomcat 2025-04-09 5.0 MEDIUM N/A
Directory traversal vulnerability in Apache HTTP Server and Tomcat 5.x before 5.5.22 and 6.x before 6.0.10, when using certain proxy modules (mod_proxy, mod_rewrite, mod_jk), allows remote attackers to read arbitrary files via a .. (dot dot) sequence with combinations of (1) "/" (slash), (2) "\" (backslash), and (3) URL-encoded backslash (%5C) characters in the URL, which are valid separators in Tomcat but not in Apache.
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-2009-1195 1 Apache 1 Http Server 2025-04-09 4.9 MEDIUM N/A
The Apache HTTP Server 2.2.11 and earlier 2.2 versions does not properly handle Options=IncludesNOEXEC in the AllowOverride directive, which allows local users to gain privileges by configuring (1) Options Includes, (2) Options +Includes, or (3) Options +IncludesNOEXEC in a .htaccess file, and then inserting an exec element in a .shtml file.
CVE-2009-1890 5 Apache, Canonical, Debian and 2 more 9 Http Server, Ubuntu Linux, Debian Linux and 6 more 2025-04-09 7.1 HIGH N/A
The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests.
CVE-2009-3095 6 Apache, Apple, Debian and 3 more 7 Http Server, Mac Os X, Debian Linux and 4 more 2025-04-09 5.0 MEDIUM N/A
The mod_proxy_ftp module in the Apache HTTP Server allows remote attackers to bypass intended access restrictions and send arbitrary commands to an FTP server via vectors related to the embedding of these commands in the Authorization HTTP header, as demonstrated by a certain module in VulnDisco Pack Professional 8.11.
CVE-2009-1955 7 Apache, Apple, Canonical and 4 more 8 Apr-util, Http Server, Mac Os X and 5 more 2025-04-09 5.0 MEDIUM 7.5 HIGH
The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, as demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564.
CVE-2007-5000 6 Apache, Canonical, Fedoraproject and 3 more 7 Http Server, Ubuntu Linux, Fedora and 4 more 2025-04-09 4.3 MEDIUM N/A

CVE-2008-0455 2 Apache, Redhat 6 Http Server, Enterprise Linux, Enterprise Linux Desktop and 3 more 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) 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 web script or HTML by uploading a file with a name containing XSS 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-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-2009-0796 1 Apache 2 Http Server, Mod Perl 2025-04-09 2.6 LOW N/A
Cross-site scripting (XSS) vulnerability in Status.pm in Apache::Status and Apache2::Status in mod_perl1 and mod_perl2 for the Apache HTTP Server, when /perl-status is accessible, allows remote attackers to inject arbitrary web script or HTML via the URI.
