ATTENTION: Exploitable remotely/low skill level to exploit
**Vendor:**Optergy
Equipment: Proton/Enterprise Building Management System
**Vulnerabilities:**Information Exposure, Cross-site Request Forgery, Unrestricted Upload of File with Dangerous Type, Open Redirect, Hidden Functionality, Exposed Dangerous Method or Function, Use of Hard-coded Credentials
Successful exploitation of these vulnerabilities could allow an attacker to achieve remote code execution and gain full system access.
The following versions of Proton/Enterprise Building Management Systems, are affected:
The application suffers from username disclosure via its username reset functionality. An attacker can enumerate and disclose all the valid users on the system. Furthermore, when calling a certain page from a remote location, the following internal information can be divulged for the current system: Name, Internal IP Address, Netmask, Hostname, Gateway, DNS Server, and DNS Server 2.
CVE-2019-7272 and CVE-2019-7277 have been assigned to these vulnerabilities. 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 affected application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious website.
CVE-2019-7273 has been assigned to this vulnerability. A CVSS v3 base score of 5.0 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L).
The vulnerability exists due to the absence of file extension validation when uploading files through the badge image upload script. A remote and unauthenticated attacker can upload files with arbitrary extensions into a directory within applicationβs web root and execute them with privileges of the web server.
CVE-2019-7274 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).
This vulnerability can be exploited to redirect a user to an arbitrary website; e.g., when a user clicks a specially crafted link to the affected script hosted on a trusted domain.
CVE-2019-7275 has been assigned to this vulnerability. A CVSS v3 base score of 3.1 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N).
Attackers can directly navigate to an undocumented backdoor script and gain full system access. This allows unauthenticated code execution with highest privileges.
CVE-2019-7276 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Unauthenticated users may be able to use undeclared class functions to access certain resources directly.
CVE-2019-7278 have been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
Attackers can use CVE-2019-7278 to send unauthorized SMS messages to any phone number depending on the stored credits to the hard-coded credentials in the function.
CVE-2019-7279 have been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
Gjoko Krstic of Applied Risk reported these vulnerabilities to Optergy.
Optergy recommends the following procedure to remediate these issues:
The latest Optergy software updates include important security updates including enhancements to prevent unwanted intrusion. In addition to these software updates, Optergy emphasizes it is important for users to ensure the site network is also secure to add an extra layer of security. To keep the Optergy system safer from unintended access, Optergy recommends the following:
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-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 on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01BβTargeted 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.
NCCIC also recommends that users take the following measures to protect themselves from social engineering attacks:
