Service crash via invalid Promise value
Published Jun 21, 2022 · Updated Aug 3, 2024
NJS 0.7.2 contains a use-after-free flaw that allows attackers to crash the process through crafted Promise aggregation inputs. The njs_vmcode_interpreter can expose an internal INVALID value while Promise.all, Promise.allSettled, Promise.any, or Promise.race iterate array-like objects, leading to a segmentation violation. Exploitation requires execution of attacker-influenced JavaScript in the NJS runtime; the documented consequence is process availability loss, with no evidence of confidentiality or integrity impact.
