CVE-2023-3042

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

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/edit_text_inc.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 DOT_URI_NORMALIZATION_FORBIDDEN_STRINGS environmental variable to add // to the list of invalid strings. 

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