CVE-2023-28708 Apache Tomcat - Information Disclosure

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:
Apache Tomcat 11.0.0-M1 to 11.0.0-M2
Apache Tomcat 10.1.0-M1 to 10.1.5
Apache Tomcat 9.0.0-M1 to 9.0.71
Apache Tomcat 8.5.0 to 8.5.85

Description:
When using the RemoteIpFilter with requests received from a reverse 
proxy via HTTP that include the X-Forwarded-Proto header set to https, 
session cookies created by Tomcat did not include the secure attribute. 
This could result in the user agent transmitting the session cookie over 
an insecure channel.

mitigations:
- - Upgrade to Apache Tomcat 11.0.0-M3 or later
- - Upgrade to Apache Tomcat 10.1.6 or later
