根据其标题，远程主机上安装的 Apache 2.4.x 版本低于 2.4.16。因此，该应用程序受到以下漏洞的影响：

  - 由于未正确处理 WebSocket PING 帧，在“mod_lua”模块的 lua_websocket_read() 函数中存在缺陷。远程攻击者可利用此缺陷，在 Lua 脚本调用 wsupgrade() 函数后发送一个构建的 WebSocket PING 帧以造成子进程崩溃，从而导致拒绝服务。(CVE-2015-0228)

  由于未能初始化协议结构成员而导致 read_request_line() 函数中存在空指针取消引用缺陷。远程攻击者可利用此缺陷，在启用 INCLUDES 过滤器且包含指定本地 URI 的 ErrorDocument 400 指令的安装下发送缺少方法的请求，以造成拒绝服务。(CVE-2015-0253)

  - 由于未能正确解析区块标头，分块传输编码实现中存在一个缺陷。远程攻击者可利用此缺陷进行 HTTP 请求走私攻击。(CVE-2015-3183)

  - 由于未考虑 Require 指令可能与授权设置而非验证设置有关，因此，ap_some_auth_required() 函数中存在一个缺陷。如果存在依赖 2.2 API 行为的模块，远程攻击者可以利用此缺陷绕过预期访问限制。
    (CVE-2015-3185)

  - 由于密钥流生成中的初始双字节偏差，RC4 算法中存在一个缺陷。攻击者可利用此缺陷，通过将先验明文发行版本和密钥流发行版本统计数据相结合的 Bayesian 分析，执行密码文本的明文恢复。请注意，根据 RFC 7465 的要求，RC4 加密套件已禁止。Apache 版本 2.4.13 中已修复此问题，但 2.4.13、2.4.14 和 2.4.15 从未公开发行。

请注意，Nessus 尚未测试这些问题，而是只依靠应用程序自我报告的版本号。

已发现在 httpd 2.4 中，内部 API 函数 ap_some_auth_required() 可能在未使用认证的情况下错误地指出请求已认证。使用此 API 函数的 httpd 模块可因此允许本应拒绝的访问。(CVE-2015-3185)

在 httpd 使用分块传输编码解析 HTTP 请求和响应的方式中发现多种缺陷。远程攻击者可使用这些缺陷创建特别构建的请求，在该请求前 httpd 将以不同于解码 HTTP 代理软件的方式对其进行解码，从而可能导致 HTTP request smuggling 攻击。(CVE-2015-3183)

在 httpd 生成特定错误消息的方式中发现空指针取消引用缺陷。远程攻击者可能利用此缺陷，借助触发特定 HTTP 错误的请求来使 httpd 子进程崩溃。(CVE-2015-0253)

在 mod_lua httpd 模块处理某些 WebSocket Ping 请求的方式中发现拒绝服务缺陷。远程攻击者可发送特别构建的 WebSocket Ping 数据包，这会导致 httpd 子进程崩溃。(CVE-2015-0228)

 Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The version of Apache HTTP Server 2.4 installed on the remote host is prior to 2.4.13. It is, therefore, affected by the following vulnerabilities : 

 - A flaw exists in the lua_websocket_read() function in the 'mod_lua' module due to incorrect handling of WebSocket PING frames. A remote attacker can exploit this, by sending a crafted WebSocket PING frame after a Lua script has called the wsupgrade() function, to crash a child process, resulting in a denial of service condition. (CVE-2015-0228) 
 - A NULL pointer dereference flaw exists in the read_request_line() function due to a failure to initialize the protocol structure member. A remote  attacker can exploit this flaw, on installations that enable the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI, by sending a request that lacks a method, to cause a denial of service condition. (CVE-2015-0253) 
 - A flaw exists in the chunked transfer coding implementation due to a failure to properly parse chunk headers. A remote attacker can exploit this to conduct HTTP request smuggling attacks. (CVE-2015-3183) 
 - A security bypass flaw affects mod_authz_svn related to a failure to properly restrict anonymous access. This may allow anonymous access in scenarios where it is intended to be restricted to authenticated users. (CVE-2015-3184) 
 - A flaw exists in the ap_some_auth_required() function due to a failure to consider that a Require directive may be associated with an authorization setting rather than an authentication setting. A remote attacker can exploit this, if a module that relies on the 2.2 API behavior exists, to bypass intended access restrictions. (CVE-2015-3185) 
 - A flaw exists in the RC4 algorithm due to an initial double-byte bias in the keystream generation. An attacker can exploit this, via Bayesian analysis that combines a priori plaintext distribution with keystream distribution statistics, to conduct a plaintext recovery of the ciphertext. Note that RC4 cipher suites are now prohibited per RFC 7465. This issue was fixed in Apache version 2.4.13; however, 2.4.13, 2.4.14, and 2.4.15 were never publicly released. (CVE-2015-2808)
