CVE-2022-34032Public exploit

Denial of service via invalid address dereference

Published Jul 18, 2022 · Updated Aug 3, 2024

Denial of service in NGINX njs 0.7.5 allows attackers who can supply trusted JavaScript code to crash the runtime. A crafted script uses an accessor on a sparse array and AggregateError, causing njs_value_own_enumerate to dereference an invalid address while constructing an error stack. Script execution is required, and NGINX treats imported JavaScript as trusted configuration; the demonstrated consequence is an affected-process abort without data disclosure or modification.
