Successful exploitation of these vulnerabilities may allow an attacker to read and write arbitrary files and sensitive data and execute commands and arbitrary code.
The following versions of CCS, a video management platform, are affected:
The user configuration menu in the web interface of CCS transfers user passwords in clear to the client (browser).
CVE-2019-13947 has been assigned to this vulnerability. A CVSS v3 base score of 4.9 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).
CCS contains an authentication bypass vulnerability in its XML-based communication protocol as provided by default on Ports 5444/TCP and 5440/TCP.
CVE-2019-18337 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
CCS contains a directory traversal vulnerability in its XML-based communication protocol as provided by default on Ports 5444/TCP and 5440/TCP.
CVE-2019-18338 has been assigned to this vulnerability. A CVSS v3 base score of 7.7 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).
CCS stores user and device passwords by applying weak cryptography.
CVE-2019-18340 has been assigned to this vulnerability. A CVSS v3 base score of 5.5 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
The SFTP service (default Port 22/TCP) of CCS contains an authentication bypass vulnerability.
CVE-2019-18341 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
The SFTP service (default Port 22/TCP) of CCS does not properly limit its capabilities to the specified purpose.
CVE-2019-18342 has been assigned to this vulnerability. A CVSS v3 base score of 9.9 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
A specific section in the web interface of CCS contains a path traversal vulnerability that could allow an authenticated remote attacker to access and download arbitrary files from the server where CCS is installed.
CVE-2019-19290 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
The FTP services of CCS maintain log files that store login credentials in cleartext. In configurations where the FTP service is enabled, authenticated remote attackers could extract login credentials of other users of the service.
CVE-2019-19291 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N).
CCS is vulnerable to an SQL injection in its XML-based communication protocol as provided by default on Ports 5444/TCP and 5440/TCP. An authenticated remote attacker could exploit this vulnerability to read or modify the CCS database and potentially execute administrative database operations or operating system commands.
CVE-2019-19292 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
The web interface of CCS contains a reflected cross-site scripting (XSS) vulnerability that could allow an unauthenticated remote attacker to steal sensitive data or execute administrative actions on behalf of a legitimate administrator of the CCS web interface.
CVE-2019-19293 has been assigned to this vulnerability. A CVSS v3 base score of 6.1 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N).
The web interface of CCS contains multiple stored XSS vulnerabilities in several input fields. This could allow an authenticated remote attacker to inject malicious JavaScript code into the CCS web application that is later executed in the browser context of any other user who views the relevant CCS web content.
CVE-2019-19294 has been assigned to this vulnerability. A CVSS v3 base score of 6.3 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N).
CCS does not enforce logging of security-relevant activities in its XML-based communication protocol as provided by default on Ports 5444/TCP and 5440/TCP. An authenticated remote attacker could exploit this vulnerability to perform covert actions not visible in the application log.
CVE-2019-19295 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N).
Raphaël Rigo of Airbus Security Lab reported some of these vulnerabilities to Siemens.
Siemens recommends users update to v1.5.0 or later.
Siemens has identified the following specific workarounds and mitigations users can apply to reduce the risk:
As a general security measure Siemens strongly recommends protecting network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices to run the devices in a protected IT environment.
For more information see SSA-761844
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.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 on the ICS webpage on us-cert.cisa.gov 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 CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
