Описание
Thymeleaf is a server-side Java template engine for web and standalone environments. Versions 3.1.3.RELEASE and prior contain a security bypass vulnerability in the the expression execution mechanisms. Although the library provides mechanisms to prevent expression injection, it fails to properly neutralize specific syntax patterns that allow for the execution of unauthorized expressions. If an application developer passes unvalidated user input directly to the template engine, an unauthenticated remote attacker can bypass the library's protections to achieve Server-Side Template Injection (SSTI). This issue has ben fixed in version 3.1.4.RELEASE.
A flaw was found in Thymeleaf, a server-side Java template engine. An unauthenticated remote attacker can exploit this vulnerability by providing unvalidated user input to the template engine. This bypasses existing security mechanisms, allowing for the execution of unauthorized expressions and leading to Server-Side Template Injection (SSTI).
Меры по смягчению последствий
The vulnerability arises when unvalidated user input is directly passed to the Thymeleaf template engine. To mitigate this, application developers should implement robust input validation and sanitization for all user-supplied data before it is processed by the Thymeleaf template engine. This ensures that malicious expressions cannot be executed.
