**ATTENTION:**Remotely exploitable/low skill level to exploit.
Vendor: LOYTEC
Equipment: LVIS-3ME
**Vulnerabilities:**Relative Path Traversal, Insufficient Entropy, Cross-site Scripting, Insufficiently Protected Credentials
The following versions of LVIS-3ME, an HMI Touch Panel, are affected:
Successful exploitation of these vulnerabilities may result in information exposure or allow arbitrary code execution.
LOYTEC has released a firmware update, V6.2.0, to address these vulnerabilities. LOYTEC recommends that users update to the latest firmware update which is available by accessing an account at the following location:

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT 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 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.
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.
In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
1.Do not click web links or open unsolicited attachments in email messages.
2.Refer to Recognizing and Avoiding Email Scamsfor more information on avoiding email scams.
3.Refer to Avoiding Social Engineering and Phishing Attacksfor more information on social engineering attacks.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are remotely exploitable. Low skill level is needed to exploit.
The web user interface fails to prevent access to critical files that non administrative users should not have access to, which could allow an attacker to create or modify files or execute arbitrary code.
CVE-2017-13996 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).
The application does not utilize sufficiently random number generation for the web interface authentication mechanism, which could allow remote code execution.
CVE-2017-13992 has been assigned to this vulnerability. A CVSS v3 base score of 8.1 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
The web interface lacks proper web request validation, which could allow XSS attacks to occur if an authenticated user of the web interface is tricked into clicking a malicious link.
CVE-2017-13994 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:L).
The application does not sufficiently protect sensitive information from unauthorized access.
CVE-2017-13998 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
Davy Douhine of RandoriSec reported the vulnerabilities to ICS-CERT.
