Security fix(es):

  • CVE-2025-53020: Apache HTTP Server: HTTP/2 DoS by Memory Increase (cve.mitre.org) Late Release of Memory after Effective Lifetime vulnerability in Apache HTTP Server. This issue affects Apache HTTP Server: from 2.4.17 up to 2.4.63. Users are recommended to upgrade to version 2.4.64, which fixes the issue. Credits: Gal Bar Nahum
  • CVE-2025-49812: Apache HTTP Server: mod_ssl TLS upgrade attack (cve.mitre.org) 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. Only configurations using "SSLEngine optional" to enable TLS upgrades are affected. Users are recommended to upgrade to version 2.4.64, which removes support for TLS upgrade.

  • CVE-2025-49630: Apache HTTP Server: mod_proxy_http2 denial of service (cve.mitre.org) 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. Configurations affected are a reverse proxy is configured for an HTTP/2 backend, with ProxyPreserveHost set to "on". Credits: Anthony CORSIEZ
  • CVE-2025-23048: Apache HTTP Server: mod_ssl access control bypass with session resumption (cve.mitre.org) 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. Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host.

  • CVE-2024-47252: Apache HTTP Server: mod_ssl error log variable escaping (cve.mitre.org) 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. In a logging configuration where CustomLog is used with "%{varname}x" or "%{varname}c" to log variables provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and unsanitized data provided by the client may appear in log files.

  • CVE-2024-43394: Apache HTTP Server: SSRF on Windows due to UNC paths (cve.mitre.org) 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. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.63. Note: The Apache HTTP Server Project will be setting a higher bar for accepting vulnerability reports regarding SSRF via UNC paths. The server offers limited protection against administrators directing the server to open UNC paths. Windows servers should limit the hosts they will connect over via SMB based on the nature of NTLM authentication. Credits: Kainan Zhang (@4xpl0r3r) from Fortinet
  • CVE-2024-43204: Apache HTTP Server: SSRF with mod_headers setting Content-Type header (cve.mitre.org) SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker. Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request. Users are recommended to upgrade to version 2.4.64 which fixes this issue. Credits: xiaojunjie@安恒信息杭州市滨江区技能大师工作室
  • CVE-2024-42516: Apache HTTP Server: HTTP response splitting (cve.mitre.org) 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. This vulnerability was described as CVE-2023-38709 but the patch included in Apache HTTP Server 2.4.59 did not address the issue. Users are recommended to upgrade to version 2.4.64, which fixes this issue.
