  • Text Web Templates Considered Harmful
    Text Web Templates considered Harmful Fernando Miguel Carvalho1[0000−0002−4281−3195], Luis Duarte1[0000−0003−3967−6254], and Julien Gouesse2 1 ADEETC, ISEL, Polytechnic Institute of Lisbon, Portugal fmcarvalho,[email protected] 2 Orange, France [email protected] Abstract. For the last decades text-based templates have been the primary op- tion to build dynamic web pages. Until today, no other alternative has rebutted this approach. Yet, using text-based templates has several drawbacks including: 1. blocking resolution, 2. programming languages heterogeneity, 3. limited set of templating features and 4. opinionated idioms. In this paper we show how a domain specific language (DSL) for HTML (such as HtmlFlow, Kotlinx.html or React JSX) can suppress the text-based templates limitations and outperform state-of-the-art template engines (such as JSP, Handlebars, Thymeleaf, and oth- ers) in well known benchmarks. To that end, we use the Spring Framework and the sample application PetClinic to show how a DSL for HTML provides unopin- ionated web templates with boundless resolving features only ruled by the host programming language (such as Java, Kotlin or JavaScript). Keywords: Web Templates · Dynamic Web Pages · Domain Specific Languages · Web Application · HTML. 1 Introduction Web templates (such as JSP, Handlebars or Thymeleaf) are based in HTML documents, which are augmented with template specific markers (e.g. <%, ffgg or $fg) representing dynamic information that can be replaced at runtime by the results of corresponding computations to produce a view [16,1]. The parsing and markers replacement process (i.e. resolution) is the main role of the template engine [31].

  • Scribbling Outside the Lines of Template Security
    Room for Escape: Scribbling Outside the Lines of Template Security Oleksandr Mirosh ([email protected]) & Alvaro Muñoz ([email protected]) ​ ​ ​ Abstract Now more than ever, digital communication and collaboration are essential to the modern human experience. People around the globe work together online as they share information, create documents, send emails, and collaborate on spreadsheets and presentations. Shared digital content is everywhere and networked communication platforms and software play a crucial role. Content Management Systems (CMS) allow the user to design, create, modify, and visualize dynamic content. For many companies, CMS platforms are pivotal to their content pipelines and workforce collaboration. In our research, we discovered multiple ways to achieve Remote Code Execution (RCE) on CMS platforms where users can create or modify templates for dynamic content. In today's multi-tenancy ecosystems, this often implies that a co-tenant on the same system can take over control of the CMS resources on which your organization relies. Using Microsoft Sharepoint and a variety of Java template engines as our main CMS attack surface, we combined implementation and design flaws with framework and language specific features to find more than twenty unique RCE vulnerabilities in Microsoft Sharepoint, Atlassian Confluence, Alfresco, Liferay, Crafter CMS, dotCMS, XWiki, Apache Ofbiz, and more. This paper presents our analysis of how these products and frameworks implement security controls and reviews techniques we used to bypass them. We describe all the vulnerabilities we uncovered in detail and show working demos of the most interesting attacks where unprivileged users can run arbitrary commands on SharePoint or Liferay servers.
