CVE-2020-35580: SearchBlox <9.2.2 - Local File Inclusion

2025-08-01 SearchBlox PoC Public

Description

SearchBlox prior to version 9.2.2 is susceptible to local file inclusion in FileServlet that allows remote, unauthenticated users to read arbitrary files from the operating system via a /searchblox/servlet/FileServlet?col=url= request. Additionally, this may be used to read the contents of the SearchBlox configuration file (e.g., searchblox/WEB-INF/config.xml), which contains both the Super Admin API key and the base64 encoded SHA1 password hashes of other SearchBlox users.
