Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions Thin web server versions prior to 1.2.4

Description The issue allows remote attackers to spoof the IP address of the client by modifying the X-Forwarded-For header, potentially hiding their activities. This is due to the reliance on the X-Forwarded-For header to determine the client's IP address in the lib/thin/connection.rb file.

Recommendations For versions prior to 1.2.4, update to version 1.2.4 or later to resolve the issue. As a temporary workaround, consider validating the X-Forwarded-For header to prevent IP address spoofing. Restrict access to sensitive areas of the web server to minimize the risk of exploitation.
