QUOTE: US-CERT is aware of public reports of a malware exploit circulating. This is a drive-by-download exploit with multiple stages and is being referred to as Gumblar. The first stage of this exploit attempts to compromise legitimate websites by injecting malicious code into them. Reports indicate that these website infections occur primarily through stolen FTP credentials but may also be compromised through poor configuration settings, vulnerable web applications, etc.
