Vulnerability Title
Unauthenticated Resource Exhaustion
Source: CVE Program / CVE List V5
Vulnerability Description
TBEA TLogger V2.1.0.0B0.0.0.0 contains an unauthenticated resource exhaustion vulnerability in its web server. An unauthenticated remote attacker can send PUT requests to the /tmp/ endpoint, causing the web server to create persistent files containing attacker-controlled data under /opt/myapp/webserver/. The generated files are not removed because the web server attempts to move them into a non-existent directory. Repeated requests can therefore exhaust available storage and cause a denial-of-service condition.
