Direct response write with header

direct-response-write-with-header

Untrusted input could be used to tamper with a web page rendering, which can lead to a Cross-site scripting (XSS) vulnerability. XSS vulnerabilities occur when untrusted input executes malicious JavaScript code, leading to issues such as account compromise and sensitive information leakage. Use ‘resp.render()’ to render safely escaped HTML. Validate the user input, perform contextual output encoding, or sanitize the input. A popular library used to prevent XSS is DOMPurify. You can also use libraries and frameworks such as Angular, Vue, and React, which offer secure defaults when rendering input.
Likelihood: HIGH
Confidence: MEDIUM
CWE:
- CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
OWASP:
- A07:2017 - Cross-Site Scripting (XSS)
- A03:2021 - Injection
