Rational ClearCase 4.1, 2002.05, and possibly other versions allows remote attackers to cause a denial of service (crash) via certain packets to port 371, e.g. via nmap.
DB4Web server, when configured to use verbose debug messages, allows remote attackers to use DB4Web as a proxy and attempt TCP connections to other systems (port scan) via a request for a URL that specifies the target IP address and port, which produces a connection status in the resulting error message.
db4web_c and db4web_c.exe programs in DB4Web 3.4 and 3.6 allow remote attackers to read arbitrary files via an HTTP request whose argument is a filename of the form (1) C: (drive letter), (2) //absolute/path (double-slash), or (3) .. (dot-dot).
