CVE-2022-30503

Name of the Vulnerable Software and Affected Versions Nginx NJS version 0.7.2

Description The issue is related to a segmentation violation in the njs set number() function, which can be caused by insufficient input data sanitization, leading to a buffer overflow. This can potentially allow a remote attacker to cause a denial of service.
