CVSS v3 7.5
ATTENTION: Remotely exploitable
Vendor: Hanwha Techwin
Equipment: Smart Security Manager
Vulnerabilities: Remote Code Execution
AFFECTED PRODUCTS
The following Smart Security Manager, a software management platform, versions
are affected:
Smart Security Manager Versions 1.5 and prior.
IMPACT
Successful exploitation of these vulnerabilities could allow an attacker to
create an arbitrary file on the server with attacker controlled data as well
as an attacker gaining root shell access. These conditions could allow remote
code execution.
MITIGATION
Hanwha Techwin has released a patch for v1.4 and v1.5. Customers using v1.4
and v1.5 need to upgrade using Patch_SSMv1.5_or_1.4_for_Cert_Vulnerability.
Customers using v1.3 and prior need to upgrade using patch SSM-TS v1.60.0.
Patches and updates can be found at this location:
http://www.hanwha-security.com/prod/info.do?menuCd=MN000185&catg1=MC000087&catg2=MC000089&catg3=&mdlCd=MC000825

NCCIC/ICS-CERT recommends that 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.
ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
ICS-CERT 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 ICSCERT 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 ICS-CERT for
tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
VULNERABILITY OVERVIEW
PATH TRAVERSAL CWE-22
