Vulnerability details
The vulnerability allows an unauthenticated remote attacker to obtain server-side PHP source code and database configuration information from WeGIA.
The vulnerability exists due to a backup file stored beneath WeGIA's public web root that Apache serves as data rather than executing as PHP when requested.
