Successful exploitation of these vulnerabilities could allow an attacker to obtain confidential information or execute remote code.
The following version of LAquis SCADA, an industrial automation software, is affected:
Processing a specially crafted project file may trigger an out-of-bounds read, which may allow an attacker to obtain sensitive information.
CVE-2019-10994 has been assigned to this vulnerability. A CVSS v3 base score of 2.5 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).
A type confusion vulnerability may be exploited when LAquis SCADA processes a specially crafted project file. This may allow an attacker to execute remote code.
CVE-2019-10980 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Francis Provencher (PRL), working with Trend Micro’s Zero Day Initiative, reported these vulnerabilities to CISA.
LCDS recommends users update to Version 4.3.1.323, which can be found at the following location:
CISA recommends users take the following measures to protect themselves from social engineering attacks:
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.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.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. These vulnerabilities are not exploitable remotely.
