Background
Mortbay Jetty is a popular open-source web server and servlet container. It provides a lightweight and scalable platform for hosting Java web applications. The vulnerability in question, identified as CVE-2007-5615, is a CRLF injection vulnerability that affects versions of Mortbay Jetty prior to 6.1.6rc0. This vulnerability allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks. HTTP response splitting attacks can lead to various security issues, including cross-site scripting (XSS) attacks, cache poisoning, and session hijacking.
Vulnerability Detail
The CRLF injection vulnerability in Mortbay Jetty allows attackers to manipulate HTTP headers by injecting newline characters (CRLF) into user-controlled input. This can result in the insertion of arbitrary headers or the modification of existing headers, leading to various attacks. By injecting malicious headers, an attacker can trick the server or client into performing unintended actions or disclose sensitive information. This vulnerability can be exploited through unspecified vectors, making it crucial to update to version 6.1.6rc0 or apply appropriate fixes to mitigate the risk.

However, as a general best practice, it is recommended to sanitize and validate user-controlled input before using it in HTTP headers. This can help prevent CRLF injection attacks and other types of injection vulnerabilities. Additionally, implementing a web application firewall (WAF) can provide an additional layer of protection against such attacks.
Conclusion
The CRLF injection vulnerability in Mortbay Jetty poses a moderate security risk, allowing attackers to manipulate HTTP headers and potentially conduct various attacks. It is crucial to update to version 6.1.6rc0 or apply the necessary fixes to mitigate this vulnerability.
