Nortel MG1000S, Signaling Server, and Call Server on the Communications Server 1000 (CS1K) 4.50.x contain multiple unspecified hard-coded accounts and passwords, which allows remote attackers to gain privileges.
_blogadata/include/init_pass2.php in Blogator-script 0.95 allows remote attackers to change the password for arbitrary users via a modified "a" parameter with a "%" wildcard symbol in the b parameter.
