CVE-2024-38476
Description
A flaw was found in httpd. Backend applications whose response headers are malicious or exploitable may allow information disclosure, server-side request forgery (SSRF) or local script execution.
Statement
This flaw can only be exploited by backend applications via malicious or exploitable response headers. For this reason, this flaw was rated with an important and not critical severity.
Red Hat Enterprise Linux 6 is not affected by this vulnerability because the vulnerable code was introduced in a newer version of httpd.
Mitigation
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Execute Unauthorized Code or Commands
An attacker could insert malicious functionality into the program by causing the program to download code that the attacker has placed into the untrusted control sphere, such as a malicious web site. This could enable the injection of malware, information exposure by granting excessive privileges or permissions to the untrusted functionality, DOM-based XSS vulnerabilities, stealing user's cookies, open redirect to malware (CWE-601), etc.
