CVSS v3 9.9

ATTENTION: Remotely exploitable/low skill level to exploit.

Vendor: Gemalto

Equipment: Sentinel License Manager

Vulnerability: Null Pointer Dereference, Buffer Overflows, Improper Access
Control


AFFECTED PRODUCTS

The following Sentinel License Manger services are affected:

    All HASP SRM, Sentinel HASP, and Sentinel LDK products prior to Sentinel LDK
    RTE 7.55


IMPACT

Successful exploitation of these vulnerabilities could lead to remote code
execution or cause a denial-of-service condition, rendering the Sentinel LDK
License Manager service unavailable.


MITIGATION

Gemalto recommends users who have Sentinel LDK run-time environment (RTE)
Version 2.10 through Version 7.54 update to Sentinel LDK RTE component Version
7.6, or the latest version. The update was available as of July 2017 and can be
found at the following location:

https://sentinelcustomer.gemalto.com/sentineldownloads/

For more information about these vulnerabilities, users can contact customer
support at:

https://supportportal.gemalto.com/csm

Or visit the vendor's customer portal at:

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities. Specifically, users should:

    Minimize network exposure for all control system devices and/or systems, and
    ensure that they are not accessible from the Internet.

    Locate control system networks and remote devices behind firewalls, and
    isolate them from the business network.

    When remote access is required, use secure methods, such as Virtual Private
    Networks (VPNs), recognizing that VPNs may have vulnerabilities and should
    be updated to the most current version available. Also recognize that VPN is
    only as secure as the connected devices.

NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.

NCCIC also provides a section for control systems security recommended practices
on the ICS-CERT web page. Several recommended practices are available for
reading and download, including Improving Industrial Control Systems
Cybersecurity with Defense-in-Depth Strategies.

Additional mitigation guidance and recommended practices are publicly available
in the NCCIC Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber
Intrusion Detection and Mitigation Strategies, that is available for download
from the ICS-CERT web site.

Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to NCCIC for tracking
and correlation against other incidents.

In addition, NCCIC recommends that users take the following measures to protect
themselves from social engineering attacks:

    Do not click web links or open unsolicited attachments in email messages.

    Refer to Recognizing and Avoiding Email Scams for more information on
    avoiding email scams.

    Refer to Avoiding Social Engineering and Phishing Attacks for more
    information on social engineering attacks.

No known public exploits specifically target these vulnerabilities.


VULNERABILITY OVERVIEW

NULL POINTER DEREFERENCE CWE-476

Language packs (zip files) with invalid HTML files lead to NULL pointer
dereferences, which could be exploited by an attacker leveraging malicious HTML
files. This could lead to a denial-of-service condition.

CVE-2017-11498 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

STACK-BASED BUFFER OVERFLOW CWE-121

Language packs containing file names longer than 1,024 characters and malformed
ASN.1 streams in input files can lead to a stack-based buffer overflow. This may
allow remote code execution.

CVE-2017-11497 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

STACK-BASED BUFFER OVERFLOW CWE-121

Malformed ASN.1 streams in V2C and similar input files can be used to generate
stack-based buffer overflows. This could allow remote code execution.

CVE-2017-11496 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

STACK-BASED BUFFER OVERFLOW CWE-121

XML payload with more than supported number of elements leads to buffer overflow
of a variable in stack. This vulnerability can be exploited for denial of
service.

CVE-2017-12818 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

STACK-BASED BUFFER OVERFLOW CWE-121

XML payload with more than supported number of elements leads to buffer overflow
of a variable in stack. This vulnerability can be exploited for denial of
service or arbitrary code execution.

CVE-2017-12821 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

HEAP-BASED BUFFER OVERFLOW CWE-122

Malformed HTTP request body in Admin APIs can be used to generate heap buffer
overflows. This vulnerability can be exploited for denial of service.

CVE-2017-12820 has been assigned to this vulnerability. A CVSS v3 base score of
7.5 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

IMPROPER ACCESS CONTROL CWE-284

License manager web interface is enabled as a default configuration, and even if
disabled, it can be re-enabled remotely. This vulnerability can be exploited to
perform above mentioned attacks remotely.

CVE-2017-12822 has been assigned to this vulnerability. A CVSS v3 base score of
9.9 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:L).
