2) Resource management error
EUVDB-ID: #VU35854
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-11993
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application while processing HTTP/2 requests with enabled trace/debug for HTTP/2 connections. A remote attacker can send specially crafted HTTP/2 requests to Apache HTTP Server and force it to make logging statements on wrong connection for certain traffic edge patterns. This results in concurrent use of memory pools for separate connections and triggers denial of service condition.
