| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-06-20 | CVE-2017-3169 | NULL Pointer Dereference vulnerability in Apache Http Server In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. | 9.8 |
| 2017-06-20 | CVE-2017-3167 | Improper Authentication vulnerability in multiple products In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. | 9.8 |
| 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 |
| 2016-07-06 | CVE-2016-1546 | Resource Management Errors vulnerability in Apache Http Server 2.4.17/2.4.18 The Apache HTTP Server 2.4.17 and 2.4.18, when mod_http2 is enabled, does not limit the number of simultaneous stream workers for a single HTTP/2 connection, which allows remote attackers to cause a denial of service (stream-processing outage) via modified flow-control windows. | 5.9 |
