What is CVE-2015-3200?

A security flaw exists in the mod_auth module of lighttpd, allowing remote attackers to manipulate log entries. This vulnerability occurs when an attacker sends a specifically crafted basic HTTP authentication string that lacks a colon character. The malformed string may contain a NULL and new line character, enabling attackers to inject arbitrary content into the server's logs. This could lead to log spoofing and potential circumvention of security measures, necessitating prompt updates to safeguard against exploitation.
