| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-07-27 | CVE-2016-0736 | Cryptographic Issues vulnerability in Apache Http Server In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption. | 7.5 |
| 2017-07-26 | CVE-2017-7659 | NULL Pointer Dereference vulnerability in Apache Http Server 2.4.24/2.4.25 A maliciously constructed HTTP/2 request could cause mod_http2 in Apache HTTP Server 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process. | 7.5 |
| 2017-07-13 | CVE-2017-9789 | Use After Free vulnerability in Apache Http Server 2.4.26 When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour. | 7.5 |
| 2017-06-20 | CVE-2017-7668 | Out-of-bounds Read vulnerability in multiple products The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. | 7.5 |
| 2016-12-05 | CVE-2016-8740 | Resource Management Errors vulnerability in Apache Http Server The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23, when the Protocols configuration includes h2 or h2c, does not restrict request-header length, which allows remote attackers to cause a denial of service (memory consumption) via crafted CONTINUATION frames in an HTTP/2 request. | 7.5 |
| 2016-07-19 | CVE-2016-5387 | The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. | 8.1 |
| 2016-07-06 | CVE-2016-4979 | Improper Access Control vulnerability in Apache Http Server 2.4.18/2.4.19/2.4.20 The Apache HTTP Server 2.4.18 through 2.4.20, when mod_http2 and mod_ssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple requests over a single connection and aborting a renegotiation. | 7.5 |
| 2009-10-13 | CVE-2009-2699 | Improper Locking vulnerability in Apache Http Server and Portable Runtime The Solaris pollset feature in the Event Port backend in poll/unix/port.c in the Apache Portable Runtime (APR) library before 1.3.9, as used in the Apache HTTP Server before 2.2.14 and other products, does not properly handle errors, which allows remote attackers to cause a denial of service (daemon hang) via unspecified HTTP requests, related to the prefork and event MPMs. | 7.5 |
| 2009-06-08 | CVE-2009-1955 | XML Entity Expansion vulnerability in multiple products 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. | 7.5 |
| 2005-02-09 | CVE-2004-0940 | Incorrect Calculation of Buffer Size vulnerability in multiple products Buffer overflow in the get_tag function in mod_include for Apache 1.3.x to 1.3.32 allows local users who can create SSI documents to execute arbitrary code as the apache user via SSI (XSSI) documents that trigger a length calculation error. | 7.8 |
