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.

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 ICS‑CERT 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

Multiple Path Traversal vulnerabilities have been identified. The flaws exist within the ActiveMQ Broker service that is installed as part of the product. By issuing specific HTTP requests, if a user visits a malicious page, an attacker can gain access to arbitrary files on the server. Smart Security Manager Versions 1.4 and prior to 1.31 are affected by these vulnerabilities. These vulnerabilities can allow for remote code execution.

CVE-2017-5168 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:H/PR:N/UI:R/S:U/C:H/I:H/A:H).

Multiple Cross Site Request Forgery vulnerabilities have been identified. The flaws exist within the Redis and Apache Felix Gogo servers that are installed as part of this product. By issuing specific HTTP Post requests, an attacker can gain system level access to a remote shell session. Smart Security Manager Versions 1.5 and prior are affected by these vulnerabilities. These vulnerabilities can allow for remote code execution.

CVE-2017-5169 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:H/PR:N/UI:R/S:U/C:H/I:H/A:H).
