CVSS 3.1
5.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:NCVE-2023-45648
Medium (5.3). EPSS 5.9% chance of exploitation in the next 30 days. Fixed in org.apache.tomcat:tomcat 10.1.14, 11.0.0-M12, 8.5.94.
Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly parse HTTP trailer headers. A specially
crafted, invalid trailer header could cause Tomcat to treat a single
request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
Older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fix the issue.
