CERT has told us of an authentication bypass flaw in Net-SNMP and UCD-SNMP.

According to net-snmp:

"The quick technical summary is that the SNMPv3 packet contains a truncated HMAC authentication code. The author that wrote the code very very long ago to check that HMAC code used the length of the packet's version of the HMAC code to do the check. Thus if you send a single byte HMAC code, it'll only check it against the first byte of HMAC output. Thus it's fairly easy to spoof an authenticated SNMPv3 packet."

The Oracle database component in Sun Management Center (Sun MC) 3.6.1, 3.6, and 3.5 Update 1 has a default account, which allows remote attackers to obtain database access and execute arbitrary code.

Unspecified vulnerability in the authentication mechanism in Solaris Management Console (SMC) on Sun Solaris 8 through 10 before 20070605 allows remote authenticated users to execute arbitrary code via unspecified vectors, related to the WBEM server.

Unspecified vulnerability in the logging mechanism in Solaris Management Console (SMC) on Sun Solaris 8 through 10 before 20070605 allows remote attackers to execute arbitrary code via unspecified vectors, related to the WBEM server.

Argument injection vulnerability in the telnet daemon (in.telnetd) in Solaris 10 and 11 (SunOS 5.10 and 5.11) misinterprets certain client "-f" sequences as valid requests for the login program to skip authentication, which allows remote attackers to log into certain accounts, as demonstrated by the bin account.
