IOActive has coordinated with Siemens regarding multiple vulnerabilities in the Ruggedcom WIN firmware. Siemens has produced firmware updates that mitigates these vulnerabilities.
These vulnerabilities could be exploited remotely if there is network access to the affected service.
The following Siemens Ruggedcom WIN versions are affected:
These vulnerabilities could allow an attacker to perform administrative actions without proper authentication.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.
Siemens is a multinational company headquartered in Munich, Germany.
Ruggedcom WIN products are used as base stations or subscriber units in wide area private wireless networks. The products are compliant to the IEEE 802.16e standard and can be operated in harsh environments. According to Siemens, these devices are deployed across several sectors including Chemical, Communications, Critical Manufacturing, Dams, Defense Industrial Base, Energy, Food and Agriculture, Government Facilities, Transportation Systems, and Water and Wastewater Systems. Siemens estimates that these products are used worldwide.
The integrated management service might allow attackers to perform administrative operations over the network without prior authentication.
CVE- 2015-1448NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-1448, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:N/C:C/I:C/A:C, web site last accessed February 03, 2015.
The integrated web server (Port 443/TCP) of the affected devices is vulnerable to a buffer overflow that might allow remote code execution.
CVE- 2015-1449NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-1449, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:N/C:C/I:C/A:C, web site last accessed February 03, 2015.
Sensitive information, such as password hashes, might be insecurely stored and might be obtained by a malicious attacker from local files or security logs.
CVE- 2015-1357NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-1357, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v2 base score of 2.6 has been assigned; the CVSS vector string is (AV:N/AC:H/Au:N/C:P/I:N/A:N).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:H/Au:N/C:P/I:N/A:N, web site last accessed February 03, 2015.
These vulnerabilities could be exploited remotely if there is network access to the affected service.
No known public exploits specifically target these vulnerabilities.
An attacker with a low skill would be able to exploit these vulnerabilities.
Siemens has produced a firmware update that mitigates these vulnerabilities and recommends updating as soon as possible. The firmware update for the affected products can be obtained for free by the following methods:

ICS-CERT encourages asset owners to take additional defensive measures to protect against this and other cybersecurity risks.
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Additional mitigation guidance and recommended practices are publicly available in the ICSβCERT Technical Information Paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/).
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.
