Microsoft » Site Server : Security Vulnerabilities, CVEs, CVSS score >= 6

Microsoft Site Server 3.0 prior to SP4 installs a default user, LDAP_Anonymous, with a default password of LdapPassword_1, which allows remote attackers the "Log on locally" privilege.

Sample web sites on Microsoft Site Server 3.0 Commerce Edition do not validate an identification number, which allows remote attackers to execute SQL commands.

IIS does not properly canonicalize URLs, potentially allowing remote attackers to bypass access restrictions in third-party software via escape characters, aka the "Escape Character Parsing" vulnerability.

Direct Mailer feature in Microsoft Site Server 3.0 saves user domain names and passwords in plaintext in the TMLBQueue network share, which has insecure default permissions, allowing remote attackers to read the passwords and gain privileges.

The Remote Data Service (RDS) DataFactory component of Microsoft Data Access Components (MDAC) in IIS 3.x and 4.x exposes unsafe methods, which allows remote attackers to execute arbitrary commands.

MS Site Server 2.0 with IIS 4 can allow users to upload content, including ASP, to the target web site, thus allowing them to execute commands remotely.
