26

FAUCET Score

CVE-2022-2053 describes a Denial of Service (DoS) vulnerability in Undertow's AjpServerRequestConduit, affecting Red Hat JBoss Fuse, Camel K, and Undertow itself. When a POST request via AJP exceeds the max-post-size limit, Undertow improperly closes the connection without a response, causing front-end proxies like mod_cluster to mark the backend worker as an error state, potentially leading to a 503 Service Unavailable for up to 10 seconds. This vulnerability has a CVSS v3.1 score of 7.5 (HIGH), indicating a network-based attack with low complexity and high impact on availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
