    CVE-2015-3183

    Published: 20 Jul 2015Last Modified: 16 Apr 2026

    Summary:

    Details: The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c.
