Vulnerabilities in this advisory

• CVE-2019-13947 — CVE-2019-13947 · CWE-317

  The user configuration menu in the web interface of the Control Center Server (CCS) transfers user passwords in clear to the client (browser). An attacker with administrative privileges for the web interface could be able to read (and not only reset) passwords of other CCS users.

• CVE-2019-18337 — CVE-2019-18337 · CWE-287

  The Control Center Server (CCS) contains an authentication bypass vulnerability in its XML-based communication protocol as provided by default on ports 5444/tcp and 5440/tcp. A remote attacker with network access to the CCS server could exploit this vulnerability to read the CCS users database, including the passwords of all users in obfuscated cleartext.

• CVE-2019-18338 — CVE-2019-18338 · CWE-23

  The Control Center Server (CCS) contains a directory traversal vulnerability in its XML-based communication protocol as provided by default on ports 5444/tcp and 5440/tcp. An authenticated remote attacker with network access to the CCS server could exploit this vulnerability to list arbitrary directories or read files outside of the CCS application context.

• CVE-2019-18340 — CVE-2019-18340 · CWE-327

  Both the SiVMS/SiNVR Video Server and the Control Center Server (CCS) store user and device passwords by applying weak cryptography. A local attacker could exploit this vulnerability to extract the passwords from the user database and/or the device configuration files to conduct further attacks.

• CVE-2019-18341 — CVE-2019-18341 · CWE-287

  The SFTP service (default port 22/tcp) of the Control Center Server (CCS) contains an authentication bypass vulnerability. A remote attacker with network access to the CCS server could exploit this vulnerability to read data from the EDIR directory (for example, the list of all configured stations).

• CVE-2019-18342 — CVE-2019-18342 · CWE-749

  The SFTP service (default port 22/tcp) of the Control Center Server (CCS) does not properly limit its capabilities to the specified purpose. In conjunction with CVE-2019-18341, an unauthenticated remote attacker with network access to the CCS server could exploit this vulnerability to read or delete arbitrary files, or access other resources on the same server.

• CVE-2019-19290 — CVE-2019-19290 · CWE-22

  The DOWNLOADS section in the web interface of the Control Center Server (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-2019-19291 — CVE-2019-19291 · CWE-313

  The FTP services of the SiVMS/SiNVR Video Server and the Control Center Server (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-2019-19292 — CVE-2019-19292 · CWE-89

  The Control Center Server (CCS) contains an SQL injection vulnerability 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-2019-19293 — CVE-2019-19293 · CWE-79

  The web interface of the Control Center Server (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-2019-19294 — CVE-2019-19294 · CWE-79

  The web interface of the Control Center Server (CCS) contains multiple stored Cross-site Scripting (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-2019-19295 — CVE-2019-19295 · CWE-778

  The Control Center Server (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 that are not visible in the application log.
