Summary
PHOENIX CONTACT: FL COMSERVER cross-site scripting (XSS) vulnerability
Notes
Summary: A cross-site scripting (XSS) vulnerability affects PHOENIX CONTACT FL COMSERVER products running firmware versions prior to 1.99, 2.20, or 2.40.
Impact: On devices with older firmware versions, an unauthenticated user with network access is able to change (but not activate) the configuration variables by accessing a specific URL on the web server, without authenticating in the web interface first. A changed configuration can only be permanently saved and activated by an authenticated user. However, since the input is not properly sanitised, an attacker could inject malicious JavaScript code. When this code is executed on the client of an authenticated user, changed configuration variables could be saved and activated without user interaction.
Remediation: PHOENIX CONTACT released new firmware versions for the affected devices, which fix this vulnerability. Customers using these devices in an unprotected network environment are recommended to update to firmware versions 1.99, 2.20, or 2.40
