7.5CVSS score

97%of all CVEs are less likely

Readycheck to confirm it

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.

Impact

An attacker can exploit this vulnerability to access sensitive information, such as configuration files, credentials, or other sensitive data stored on the server.

Fix

Upgrade to SearchBlox version 9.2.2 or later to mitigate the vulnerability.

How to confirm it

Send: GET {{BaseURL}}/searchblox/servlet/FileServlet?col=9&url=/etc/passwd
