Server-side template injection attacks can occur when user input is concatenated directly into a template, rather than passed in as data. This allows attackers to inject arbitrary template directives in order to manipulate the template engine, often enabling them to take complete control of the server.
To detect Server-Side Template Injection (SSTI), initially, fuzzing the template is a straightforward approach. This involves injecting a sequence of special characters ( ${{<%[%'"}}%\ ) into the template and analyzing the differences in the server's response to regular data versus this special payload.
Jun 10, 2024 · A template engine generates a web page by combining a fixed template with volatile data. Attackers use the server-side template injection technique to directly insert user input into templates, allowing them to introduce arbitrary directives that alter the template engine’s behavior.
Aug 5, 2015 · Back to all articles. Template engines are widely used by web applications to present dynamic data via web pages and emails. Unsafely embedding user input in templates enables Server-Side Template Injection, a frequently c.
server-side template injection. This lab is vulnerable to server-side template injection due to the unsafe construction of an ERB template. To solve the lab, review the ERB documentation to find out how to execute arbitrary code, then delete the morale.txt file from Carlos's home directory.
Dec 24, 2020 · Read the Pentester’s Guide to Server-Side Template Injection (SSTI) for insights into this common vulnerability with expert tips from Busra Demir at Cobalt.
Jan 1, 2023 · Server-Side Template Injection (SSTI) occurs when an attacker injects a malicious payload into a template using native template syntax and causes it to execute on the server.
Mar 3, 2024 · Server-Side Template Injection (SSTI) is a critical vulnerability that can compromise the security of web applications. It occurs when user input is embedded within templates processed by...
Dec 29, 2021 · A server-side template injection (SSTI) vulnerability occurs when user data is embedded directly in a template and then interpreted by the template engine. This allows attackers to inject arbitrary directives to manipulate the template engine.
Dec 31, 2020 · Template Injection, also known as Server-Side Template Injection (SSTI) is a vulnerability class that has established the foundations for the exploitation techniques in multiple template...
