Deskripsi CVE
Schneider Electric SCADA Expert ClearSCADA Improper Authentication
Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 allows remote attackers to read database records by leveraging access to the guest account.Solusi CVE
Schneider Electric advises all ClearSCADA users to take steps to
secure the interfaces to the ClearSCADA system. The ClearSCADA database
security configuration should be reviewed and updated to limit all
system access to authorized users only. The access permissions of
existing users should be reduced to only those required by their role
(e.g., removing any higher level System Administration privileges from
Operations or Engineering users), and specific accounts should be
created with appropriate permissions for performing System
Administration tasks.
Existing ClearSCADA customers using WebX can protect their system
from cross-site scripting attacks by disabling the “Allow database
shutdown via WebX” option within the ClearSCADA Server Configuration
utility.
Existing ClearSCADA customers should take measures to ensure their
system does not grant any system access until users have supplied a
valid username and password.
Schneider Electric has corrected the default user security
permissions; however, upgrading an existing vulnerable installation to a
new version will not affect existing configured database security
permissions. Therefore, the measures suggested here are strongly
recommended for all users.
Schneider Electric has corrected these vulnerabilities in the following service packs:
* ClearSCADA 2010 R3.2, Released October 2014, and
* SCADA Expert ClearSCADA 2014 R1.1, Released October 2014.
If asset owners wish to upgrade to a new ClearSCADA Service Pack,
please contact the local Schneider Electric office for the latest
software version for ClearSCADA; alternatively, these new versions are
available for direct download from the Schneider Electric web site. To
update their license (not required when upgrading to a service pack of
the same version), asset owners are required to complete and submit an
online form, which is available here:

EPSS
EPSS adalah model penilaian yang memprediksi kemungkinan suatu kerentanan dieksploitasi.
Skor EPSS
Model EPSS menghasilkan skor probabilitas antara 0 dan 1 (0 hingga 100%). Semakin tinggi skor, semakin besar probabilitas bahwa suatu kerentanan akan dieksploitasi.
Persentil EPSS
Persentil digunakan untuk meranking CVE berdasarkan skor EPSS mereka. Misalnya, CVE di persentil ke-95 berdasarkan skor EPSS-nya lebih mungkin dieksploitasi daripada 95% CVE lainnya. Dengan demikian, persentil digunakan untuk membandingkan skor EPSS suatu CVE dengan CVE lainnya.
