Operating System: Windows

Cause

The following CVE's have been published for Apache HTTP Server 2.4.61 and older.

===============================

CVE-2024-40725: source code disclosure with handlers configured via AddType
SEVERITY: Important
DESCRIPTION: A partial fix for CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 ignores some use of the legacy content-type based configuration of handlers. "AddType" and similar configuration, under some circumstances where files are requested indirectly, result in source code disclosure of local content. For example, PHP scripts may be served instead of interpreted.

IMPACTED: <=2.4.61
REDEMIATION: Apache 2.4.62
-------------------------------------
CVE-2024-40898: SSRF with mod_rewrite in server/vhost context on Windows
SEVERITY: Important
DESCRIPTION: SSRF in Apache HTTP Server on Windows with mod_rewrite in server/vhost context, allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests.

IMPACTED: <=2.4.61
REDEMIATION: Apache 2.4.62
-------------------------------------

CVE-2024-36387 "Apache HTTP Server: DoS by Null pointer in websocket over HTTP/2"
SEVERITY: low
DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38472: "Apache HTTP Server on WIndows UNC SSRF"
SEVERITY:  important
DESCRIPTION: SSRF in Apache HTTP Server on Windows allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests or content

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38473: "Apache HTTP Server proxy encoding problem"
SEVERITY:  moderate
DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38474: "Apache HTTP Server weakness with encoded question marks in backreferences"
SEVERITY:  important

DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38475: "Apache HTTP Server weakness in mod_rewrite when first segment of substitution matches filesystem path"
SEVERITY:  important

DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38476: "Apache HTTP Server may use exploitable/malicious backend application output to run local handlers via internal redirect"
SEVERITY:  important
DESCRIPTION: 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.

Note: Some legacy uses of the 'AddType' directive to connect a request to a handler must be ported to 'SetHandler' after this fix.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-38477: "Apache HTTP Server: Crash resulting in Denial of Service in mod_proxy via a malicious request"
SEVERITY:  important

DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60

-------------------------------------
CVE-2024-39573: "Apache HTTP Server: mod_rewrite proxy handler substitution"
SEVERITY: Moderate
DESCRIPTION: 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.

IMPACTED: <=2.4.59
REDEMIATION: Apache 2.4.60
