Title

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

Summary

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

GHSA-4473-7649-RJ9X

Vulnerability from github – Published: 2023-10-18 00:31 – Updated: 2024-09-30 18:31

Details

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.

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

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
