Description
Traccar is an open source GPS tracking system. Default installs of Traccar on Windows between versions 6.1- 6.8.1 and non default installs between versions 5.8 - 6.0 are vulnerable to unauthenticated local file inclusion attacks which can lead to leakage of passwords or any file on the file system including the Traccar configuration file.
