Sambar Server before 6.0 beta 3 allows attackers with physical access to execute arbitrary code via a request with an MS-DOS device name such as com1.pl, con.pl, or aux.pl, which causes Perl to read the code from the associated device.

Multiple cross-site scripting (XSS) vulnerabilities in Sambar Server before 6.0 beta 6 allow remote attackers to inject arbitrary web script or HTML via the query string to (1) isapi/testisa.dll, (2) testcgi.exe, (3) environ.pl, (4) the query parameter to samples/search.dll, (5) the price parameter to mortgage.pl, (6) the query string in dumpenv.pl, (7) the query string to dumpenv.pl, and (8) the E-Mail field of the guestbook script (book.pl).

HTTP Proxy in Sambar Server before 6.0 beta 6, when security.ini lacks a 127.0.0.1 proxydeny entry, allows remote attackers to send proxy HTTP requests to the Sambar Server's administrative interface and external web servers, by making a "Connection: keep-alive" request before the proxy requests.

Sambar Telnet Proxy/Server allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long password.

The default configuration of Sambar Server 5 and earlier uses a symmetric key that is compiled into the binary program for encrypting passwords, which could allow local users to break all user passwords by cracking the key or modifying a copy of the sambar program to call the decryption procedure.

Directory traversal vulnerability in pagecount CGI script in Sambar Server before 5.0 beta 5 allows remote attackers to overwrite arbitrary files via a .. (dot dot) attack on the page parameter.
