CVSS v3 7.8
ATTENTION: Exploitable remotely/low skill level to exploit
Vendor: LCDS - Leão Consultoria e Desenvolvimento de Sistemas Ltda ME
Equipment: LAquis SCADA
Vulnerabilities: Improper Input Validation, Out-of-Bounds Read, Code Injection, Untrusted Pointer Dereference, Out-of-Bounds Write, Relative Path Traversal, Injection, Use of Hard-Coded Credentials, Authentication Bypass Using an Alternate Path or Channel
Successful exploitation of these vulnerabilities could allow remote code execution, data exfiltration, or cause a system crash.
The following versions of LAquis SCADA, an industrial automation software, are affected:
Opening a specially crafted report format file allows execution of script code, which may allow remote code execution, data exfiltration, or cause a system crash.
CVE-2018-18988 has 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).
Opening a specially crafted project file may cause an out of bounds read, which may allow data exfiltration.
CVE-2018-19004 has been assigned to this vulnerability. A CVSS v3 base score of 3.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).
Opening a specially crafted project file may cause improper control of generation of code, which may allow remote code execution, data exfiltration, or cause a system crash.
CVE-2018-19002 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).
An attacker using a specially crafted project file can supply a pointer for a controlled memory address, which may allow remote code execution, data exfiltration, or cause a system crash.
CVE-2018-19029 has 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).
Opening specially crafted report format file may cause an out of bounds read, which may cause a system crash, allow data exfiltration, or remote code execution.
CVE-2018-18986 has 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).
The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose sensitive information under the context of the web server process.
CVE-2018-18990 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).
Opening specially crafted project file may cause an out of bounds read, which may cause a system crash or allow data exfiltration.
CVE-2018-18994 has 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).
Taking in user input without proper sanitation may allow an attacker to execute remote code on the server.
CVE-2018-18992 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:L/PR:N/UI:R/S:U/C:L/I:L/A:L).
Taking in user input without proper authorization or sanitation may allow an attacker to execute remote code on the server.
CVE-2018-18996 has 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).
Use of hard coded credentials may allow an attacker unauthorized access to the system with high-privileges.
CVE-2018-18998 has 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).
An authentication bypass is possible, which may allow an attacker access to sensitive data.
CVE-2018-19000 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).
Esteban Ruiz (mr me) working with Zero Day Initiative reported these vulnerabilities to NCCIC.
LCDS recommends users update to Version 4.1.0.4150 which can be found at the following location:
NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
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-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
NCCIC also recommends that users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities.
