Bug ID: 62383
Summary: HttpParser.DomainParserState fails valid hostname
gateway.demo-ilt-latest-demo:9000
Product: Tomcat 8
Version: 8.5.31
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P2
Component: Util
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ----
We recently upgraded to Tomcat 8.5.31 and found that it's rejecting the
hostname gateway.demo-ilt-latest-demo:9000 with the following message:
The character [:] is not valid after a letter in a domain name.
I traced the code on GitHub to
https://github.com/apache/tomcat/blob/trunk/java/org/apache/tomcat/util/http/parser/HttpParser.java#L875
Looking at the history of this file, it appears that there have been quite a
few problems with the hostname verification. I'd like to know why the above
hostname is considered invalid. FWIW, name
gateway.demo-ilt-latest-demo.svc.cluster.local works.
