CVE-2018-13992

Name of the Vulnerable Software and Affected Versions PHOENIX CONTACT FL SWITCH 3xxx, 4xxx, 48xx versions 1.0 through 1.34

Description The WebUI of the affected devices allows for plaintext transmission of user credentials by default, which can be done over HTTP.

Recommendations For versions 1.0 through 1.34, consider configuring the WebUI to use encrypted transmission, such as HTTPS, to protect user credentials. As a temporary workaround, restrict access to the WebUI to minimize the risk of exploitation.
