According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
    (CVE-2022-26377)

  - The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an     attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with     mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use     the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against     current headers to resolve the issue. (CVE-2022-28614)

  - Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected. (CVE-2022-28615)

  - In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size. (CVE-2022-29404)

  - If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input     to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
    (CVE-2022-30522)

  - Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point     past the end of the storage allocated for the buffer. (CVE-2022-30556)

  - Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on     client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on     the origin server/application. (CVE-2022-31813)

The remote Ubuntu 16.04 ESM / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5487-3 advisory.

    USN-5487-1 fixed several vulnerabilities in Apache HTTP Server. Unfortunately it caused regressions.
    USN-5487-2 reverted the patches that caused the regression in Ubuntu 14.04 ESM for further investigation.
    This update re-adds the security fixes for Ubuntu 14.04 ESM and fixes two different regressions: one     affecting mod_proxy only in Ubuntu 14.04 ESM and another in mod_sed affecting also Ubuntu 16.04 ESM and     Ubuntu 18.04 LTS.

    We apologize for the inconvenience.

    (CVE-2022-26377)

  - 當設定為使用 mod_isapi 模組處理要求時，Windows 主機上的 HTTP Server 2.4.53 和更舊版本可能會發生超出邊界讀取問題。(CVE-2022-28330)

  - 在 Apache HTTP Server 2.4.53 及更早版本中，若攻擊者能夠使用 ap_rwrite() 或 ap_rputs() (例如使用 mod_luas r:puts() 函式 ) 讓伺服器反映超大型輸入，則 ap_rwrite() 函式可能會讀取非預期的記憶體。從使用「ap_rputs」函式的 Apache HTTP Server 分別編譯和發佈的模組，必須針對目前的標頭編譯非常大 (INT_MAX 或更大) 的字串，才能解決此問題。(CVE-2022-28614)

  在 Apache HTTP Server 2.4.53 和更舊版本中，當應用程式處理超大型輸入緩衝區時，ap_strcmp_match() 中的超出邊界讀取弱點可能會造成應用程式損毀或資訊洩漏。雖然無法將隨伺服器發佈的程式碼強制轉換為此類呼叫，但使用 ap_strcmp_match() 的第三方模組或 lua 指令碼可能會受到影響。(CVE-2022-28615)

  - 在 Apache HTTP Server 2.4.53 和更舊版本中，由於對可能的輸入大小沒有預設限制，惡意要求呼叫 parsebody(0) 的 lua 指令碼可能會造成應用程式拒絕服務。(CVE-2022-29404)

  - 如果將 Apache HTTP Server 2.4.53 設定為在 mod_sed 的輸入可能非常大的環境中使用 mod_sed 進行轉換，則 mod_sed 可能會進行超大記憶體配置並觸發中止。
    (CVE-2022-30522)

  - Apache HTTP Server 2.4.53 及更舊版本可能會向呼叫 r: wsread() 的應用程式傳回指向超出為緩衝區配置的儲存區結尾的長度。(CVE-2022-30556)

  - Apache HTTP Server 2.4.53 及更舊版本可能不會根據用戶端的 Connection 標頭逐跳機制將 X-Forwarded-* 標頭傳送至原始伺服器。攻擊者可利用此問題繞過原始伺服器/應用程式上的 IP 型驗證。(CVE-2022-31813)
