SB20240717136 - Multiple vulnerabilities in Apache HTTP Server

Description

This security bulletin contains information about 2 vulnerabilities.

1) Information disclosure (CVE-ID: CVE-2024-40725)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error when processing legacy content-type based configuration of handlers, such as "AddType" and similar configuration when files are requested indirectly. A remote attacker can send a specially crafted HTTP request and view contents of files, for example the source code of a PHP script can be served instead of interpreted.

Note, the vulnerability exists due to incomplete fix for #VU93729 (CVE-2024-39884).

2) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-40898)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N/E:P/U:Amber

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in Apache HTTP Server on Windows with mod_rewrite in server/vhost context. A remote attacker can force the web server to leak NTML hashes to a malicious server via SSRF and malicious requests.

Remediation

Install update from vendor's website.
