Summary
CNA SHORTNAME: dotCMSORG UUID: 5b9d93f2-25c7-46b4-ab60-d201718c9dd8
Details

In dotCMS, versions mentioned, a flaw in the NormalizationFilter does not strip double slashes (//) from URLs, potentially enabling bypasses for XSS and access controls. An example affected URL is https://demo.dotcms.com//html/portlet/ext/files/edittextinc.jsp , which should return a 404 response but didn't.

The oversight in the default invalid URL character list can be viewed at the provided GitHub link https://github.com/dotCMS/core/blob/master/dotCMS/src/main/java/com/dotcms/filters/NormalizationFilter.java#L37 . 

To mitigate, users can block URLs with double slashes at firewalls or utilize dotCMS config variables.

Specifically, they can use the DOTURINORMALIZATIONFORBIDDENSTRINGS environmental variable to add // to the list of invalid strings.

Additionally, the DOTURINORMALIZATIONFORBIDDENREGEX variable offers more detailed control, for instance, to block //html.* URLs.

Fix Version:23.06+, LTS 22.03.7+, LTS 23.01.4+
