Successful exploitation of these vulnerabilities could allow access to sensitive information.
Siemens reports that the vulnerabilities affect all versions prior to 3.2.1 of the following SIMATIC RF6XXR UHF RFID products:
3.2.1 IMPROPER INPUT VALIDATION CWE-20
The SSL protocol encrypts data by using CBC mode with chained initialization vectors, which may allow a man-in-the-middle attack to obtain plaintext HTTP headers.
CVE-2011-3389 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
3.2.2 CRYPTOGRAPIC ISSUES CWE-310
Long-duration TLS sessions used with a 64-bit block cipher may allow remote attackers to obtain cleartext data.
CVE-2016-6329 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
3.2.3 CRYPTOGRAPIC ISSUES CWE-310
Outdated versions of TLS and DTLS allow statistical analysis of timing data for crafted packets, which may allow remote attackers to conduct distinguishing and plaintext-recovery attacks.
CVE-2013-0169 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
Wendy Parrington from United Utilities reported these vulnerabilities to Siemens.
Siemens recommends users upgrade to Version 3.2.1 or newer for both affected products.
Siemens also recommends users restrict network access to the device.
For more information on these vulnerabilities and associated software updates, please see Siemens’ security advisory SSA-556833 at: https://www.siemens.com/cert/advisories.
NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
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 webpage on us-cert.gov. 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 Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
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.
High skill level is needed to exploit.
