6DescriptionNVD
A vulnerability exists in the ngx_http_scgi_module and ngx_http_uwsgi_module modules that may result in excessive memory allocation or an over-read of data. When scgi_pass or uwsgi_pass is configured, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to read the memory of the NGINX worker process or restart it. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
AnalysisAI
Memory disclosure and denial-of-service in NGINX's SCGI and uWSGI proxy modules allow attackers with man-in-the-middle position between NGINX and upstream servers to read worker process memory or crash the service. Affects both NGINX Open Source and NGINX Plus when scgi_pass or uwsgi_pass directives are configured. …
Sign in for full analysis, threat intelligence, and remediation guidance.
RemediationAI
Within 24 hours: Inventory all NGINX deployments using scgi_pass or uwsgi_pass directives and verify network segmentation between NGINX and upstream servers. Within 7 days: Apply vendor-released patch to all affected NGINX instances (Open Source and Plus versions); consult vendor advisory for specific patched versions. …
