Synopsis

Spring Boot Actuator Logview < 0.2.13 Directory Traversal

Description

Spring Boot Actuator Logview is a library that adds a simple logfile viewer as Spring Boot Actuator endpoint. In Spring Boot Actuator Logview before version 0.2.13 there is a directory traversal vulnerability. The nature of this library is to expose a log file directory via admin (Spring Boot Actuator) HTTP endpoints. Both the filename to view and a base folder can be specified via request parameters. While the filename parameter was checked to prevent directory traversal exploits, the base folder parameter was not sufficiently checked.

Solution

Update to Spring Boot Actuator Logview version 0.2.13 or latest.
