HP Data Protector 7.0x < 7.03 build 108 / 8.1x < 8.15 / 9.0x < 9.06 Multiple Vulnerabilities (HPSBGN03580) (Bar Mitzvah)

Synopsis :

The remote host is affected by multiple vulnerabilities.

Description :

The version of HP Data Protector installed on the remote host is 7.0x
prior to 7.03 build 108, 8.1x prior to 8.15, or 9.0x prior to 9.06. It
is, therefore, affected by the following vulnerabilities :

- A security feature bypass vulnerability exists, known as
Bar Mitzvah, due to improper combination of state data
with key data by the RC4 cipher algorithm during the
initialization phase. A man-in-the-middle attacker can
exploit this, via a brute-force attack using LSB values,
to decrypt the traffic. (CVE-2015-2808)

- A flaw exists due to a failure to authenticate users,
even with Encrypted Control Communications enabled. An
unauthenticated, remote attacker can exploit this to
execute arbitrary code. (CVE-2016-2004)

- Multiple overflow conditions exist due to improper
validation of user-supplied input. An unauthenticated,
remote attacker can exploit these issues, via specially
crafted 'User Name' or 'Domain' field in an EXEC_BAR
request, to cause a stack-based buffer overflow,
resulting in a denial of service or the execution of
arbitrary code. (CVE-2016-2005, CVE-2016-2006)

- An overflow condition exists due to improper validation
of user-supplied input. An unauthenticated, remote
attacker can exploit this, via specially crafted
EXEC_SCRIPT request, to cause a stack-based buffer
overflow, resulting in a denial of service or the
execution of arbitrary code. (CVE-2016-2007)

- An unspecified flaw exists that allows an
unauthenticated, remote attacker to disclose sensitive
information or execute arbitrary code. (CVE-2016-2008)
