CVE-2006-4191

Status: ModifiedMedium (5.1)—

Directory traversal vulnerability in memcp.php in XMB (Extreme Message Board) 1.9.6 and earlier allows remote attackers to include and execute arbitrary local files via directory traversal sequences in the langfilenew parameter, as demonstrated by injecting PHP sequences into an Apache HTTP Server log file, which is then included by header.php.

CVSS

Version: 2.0
Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
