CVE-2006-4847 describes multiple buffer overflow vulnerabilities in Ipswitch WS_FTP Server 5.05 prior to Hotfix 1, affecting both Ipswitch and Progress versions of the software. Authenticated attackers can exploit these flaws by sending overly long XCRC, XSHA1, or XMD5 commands, leading to arbitrary code execution. With a CVSS score of 6.5, this vulnerability is of medium severity, requiring network access and authentication for exploitation, but potentially allowing for complete compromise of confidentiality, integrity, and availability.
