Security readout for executives and security teams
CVE-2021-36160 is a denial-of-service flaw in Apache HTTP Server's mod_proxy_uwsgi. A specially crafted request path can make affected servers read outside allocated memory and crash. The sourced affected range is Apache HTTP Server 2.4.30 through 2.4.48 inclusive. Exposure is most likely where Apache HTTP Server 2.4.30-2.4.48 is deployed with mod_proxy_uwsgi enabled or configured to proxy uWSGI applications. Internet-facing reverse proxies have higher business impact because a crash can interrupt public service availability. Treat this as a moderate availability risk. It is not presented as data theft or remote code execution, but public web infrastructure can still suffer outages. Patch exposed Apache reverse proxies first, especially systems supporting revenue, customer portals, or critical operations. Mitigation focus: Inventory Apache HTTP Server versions and identify deployments in the 2.4.30-2.4.48 range.; Identify where mod_proxy_uwsgi is enabled or used for uWSGI application proxying.; Apply Apache or operating-system vendor security updates that move systems outside the affected range..
