Apache 2.4.x < 2.4.64 Multiple Vulnerabilities

high Web App Scanning Plugin ID 114917

Synopsis

Apache 2.4.x < 2.4.64 Multiple Vulnerabilities

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.64. It is, therefore, affected by multiple vulnerabilities:

- HTTP response splitting in the core of Apache HTTP Server allows an attacker who can manipulate the Content-Type response headers of applications hosted or proxied by the server can split the HTTP response. (CVE-2024-42516)

- Server-Side Request Forgery (SSRF) in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker. (CVE-2024-43204)

- Server-Side Request Forgery (SSRF) in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via mod_rewrite or apache expressions that pass unvalidated request input. (CVE-2024-43394)

- Insufficient escaping of user-supplied data in mod_ssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations. (CVE-2024-47252)

- In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.62, an access control bypass by trusted clients is possible using TLS 1.3 session resumption. (CVE-2025-23048)

- In certain proxy configurations, a denial of service attack against Apache HTTP Server versions 2.4.26 through to 2.4.63 can be triggered by untrusted clients causing an assertion in mod_proxy_http2. (CVE-2025-49630)

- In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade. (CVE-2025-49812)

- Late Release of Memory after Effective Lifetime vulnerability in Apache HTTP Server. (CVE-2025-53020) Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.64 or later.
