Changes with Apache 2.4.60
*) SECURITY: CVE-2024-39573: Apache HTTP Server: mod_rewrite proxy handler substitution (cve.mitre.org) Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-38477: Apache HTTP Server: Crash resulting in Denial of Service in mod_proxy via a malicious request (cve.mitre.org) null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash the server via a malicious request. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-38476: Apache HTTP Server may use exploitable/malicious backend application output to run local handlers via internal redirect (cve.mitre.org) Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-38475: Apache HTTP Server weakness in mod_rewrite when first segment of substitution matches filesystem path. (cve.mitre.org) Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained.

*) SECURITY: CVE-2024-38474: Apache HTTP Server weakness with encoded question marks in backreferences (cve.mitre.org) Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI. Users are recommended to upgrade to version 2.4.60, which fixes this issue.
Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag "UnsafeAllow3F" is specified. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-38473: Apache HTTP Server proxy encoding problem (cve.mitre.org) Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-38472: Apache HTTP Server on WIndows UNC SSRF (cve.mitre.org) SSRF in Apache HTTP Server on Windows allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests or content
Users are recommended to upgrade to version 2.4.60 which fixes this issue. Note: Existing configurations that access UNC paths will have to configure new directive "UNCList" to allow access during request processing. Credits: Orange Tsai (@orange_8361) from DEVCORE
*) SECURITY: CVE-2024-36387: Apache HTTP Server: DoS by Null pointer in websocket over HTTP/2 (cve.mitre.org) Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference, leading to a crash
of the server process, degrading performance. Credits: Marc Stern (<marc.stern approach.be>)
*) mod_proxy: Fix DNS requests and connections closed before the configured addressTTL. BZ 69126. [Yann Ylavic]
*) core: On Linux, log the real thread ID in error logs. [Joe Orton]
*) core: Support zone/scope in IPv6 link-local addresses in Listen and VirtualHost directives (requires APR 1.7.x or later). PR 59396 [Joe Orton]
*) mod_ssl: Reject client-initiated renegotiation with a TLS alert (rather than connection closure). [Joe Orton, Yann Ylavic]
*) Updated mime.types. [Mohamed Akram <mohd.akram outlook.com>, Adam Silverstein <adamsilverstein earthboundhosting.com>]
*) mod_ssl: Fix a regression that causes the default DH parameters for a key no longer set and thus effectively disabling DH ciphers when no explicit DH parameters are set. PR 68863 [Ruediger Pluem]
*) mod_cgid: Optional support for file descriptor passing, fixing error log handling (configure --enable-cgid-fdpassing) on Unix platforms. PR 54221. [Joe Orton]
*) mod_cgid/mod_cgi: Distinguish script stderr output clearly in error logs. PR 61980. [Hank Ibell <hwibell gmail.com>]
*) mod_tls: update version of rustls-ffi to v0.13.0. [Daniel McCarney (@cpu}]
*) mod_md:
- Using OCSP stapling information to trigger certificate renewals. Proposed by @frasertweedale.
- Added directive `MDCheckInterval` to control how often the server checks for detected revocations. Added proposals for configurations in the README.md chapter "Revocations".
- OCSP stapling: accept OCSP responses without a `nextUpdate` entry which is allowed in RFC 6960. Treat those as having an update interval of 12 hours. Added by @frasertweedale.
- Adapt OpenSSL usage to changes in their API. By Yann Ylavic.
The stable version of Apache HTTP Server 2.4.60 is now available following four release candidates. Apache HTTP Server 2.4.60 has been upgraded to address a number of security vulnerabilities. These include a potential SSRF in mod_rewrite, a crash resulting in denial of service in mod_proxy caused by a malicious request, a vulnerability in the core of Apache HTTP Server 2.4.59 and earlier, a vulnerability in mod_rewrite when the first segment of substitution matches the filesystem path, a weakness with encoded question marks in backreferences, and a proxy encoding issue. Users should upgrade to version 2.4.60 to address these vulnerabilities.
