CRLF Injection allows the attacker to set fake cookies, steal CSRF tokens, disclose user information by injecting a script (XSS) and perform a variety of other attacks.
A CRLF Injection attack occurs when a user manages to submit a CRLF into an application. This is most commonly done by modifying an HTTP parameter or URL. CRLFsuite — Fast CRLF injection scanning tool.
In web applications a CRLF injection can have severe impacts, depending on what the application does with single items. Impacts can range from information disclosure to code execution, a direct impact web application security vulnerability.
A good example of session fixation (with CRLF injection) comes from the CVE-2017-5868 and is explained in this post. 1. An attacker notice that the parameter __session_start in OpenVPN is vulnerable to CRLF injection.
CRLF Injection Regexp 'Detect in response': request payloads: 29 lines (25 sloc) 716 Bytes.
The CRLF injection template's matcher is too lax resulting in false positives in particular when encountering Citrix Gateways.
In this case, Chariot performed testing for CRLF injection vulnerabilities using the Nuclei scanning utility. Figure 2 shows an example request in the finding Chariot generated. Figure 2: An example CRLF injection vulnerability Chariot discovered automatically.
The following simplified example uses CRLF to: 1. Add a fake HTTP response header: Content-Length: 0. This causes the web browser to treat this as a terminated response and begin parsing a new response.
In a CRLF injection vulnerability attack, the attacker inserts both the carriage return and linefeed characters into user input to trick the server, the web application or the user into thinking that an object is terminated and another one has started.
Конечно, эта CRLF Injection не бесполезная и ее можно попробовать использовать в комбинации с другими уязвимостями типа Session Fixation или для обхода каких-либо проверок cookie-значений…
It redirects me to /login, which is log out the current session, and also set a new session cookie!
