Name of the Vulnerable Software and Affected Versions
NGINX JavaScript (affected versions not specified)
Description
A flaw in NGINX JavaScript allows a remote attacker to cause a denial-of-service (DoS) on the system. The issue occurs when the
ngx.fetch() function receives a malformed HTTP response and trusted JavaScript subsequently reads the Response.statusText property, leading to a crash of the NGINX worker. Successful exploitation requires the attacker to have control or influence over the fetched HTTP response. This is a data plane issue and does not expose the control plane.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
