The NCCIC has published an advisory on a stack-based buffer overflow vulnerability in Fuji Electric Alpha5 Smart Loader. All versions prior to 4.2 are affected. Successful exploitation of this vulnerability could allow an attacker to execute code under the privileges of the application. Fuji Electric has released version 4.2 of the Alpha Loader software. The NCCIC also recommends a series of measures to mitigate the vulnerabilities. Read the advisory at CISA.

Johnson Controls Metasys (ICSA-19-227-01)

The NCCIC has published an advisory on reusing a nonce, key pair in encryption and on the use of hard-coded cryptographic key vulnerabilities in Johnson Controls Metasys.

Microsoft Releases Security Updates to Address Remote Code Execution Vulnerabilities

Microsoft has released security updates to address two remote code execution vulnerabilities, CVE-2019-1181 and CVE-2019-1182, in its operating systems. An attacker could exploit these vulnerabilities to take control of an affected system. Similar to CVE-2019-0708 - dubbed BlueKeep - these vulnerabilities are considered “wormable” because malware exploiting these vulnerabilities on a system could propagate to other vulnerable systems.

Multiple HTTP/2 Implementation Vulnerabilities

The CERT Coordination Center (CERT/CC) has released information on vulnerabilities affecting HTTP/2 implementations. An attacker could exploit these vulnerabilities to cause a denial-of-service (DoS) condition. Attacks can consume excessive system resources and lead to distributed DoS (DDoS) attacks. The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review CERT/CC’s Vulnerability Note VU#605641 for more information and refer to vendors for updates.

Delta Industrial Automation DOPSoft (ICSA-225-01)

The NCCIC has published an advisory on out-of-bounds read and use after free vulnerabilities in Delta Industrial Automation DOPSoft. DOPSoft Version 4.00.06.15 and prior are affected. Successful exploitation of these vulnerabilities may allow information disclosure, remote code execution, or crash of the application. Delta recommends users update to the latest version of DOPSoft, version 4.00.06.47, and restrict interaction with the application to trusted files. The NCCIC also recommends a series of measures to mitigate the vulnerabilities.

OSIsoft PI Web API (ICSA-19-225-02) – Products Used in the Water and Wastewater and Energy Sectors

The NCCIC has published an advisory on inclusion on sensitive information in log files and protection mechanism failure vulnerabilities in OSIsoft PI Web API. PI Web API 2018 and prior are affected. Successful exploitation of these vulnerabilities may allow direct attacks against the product and disclose sensitive information. OSIsoft recommends users upgrade to PI Web API 2018 SP1 or later to resolve these issues. The NCCIC also recommends a series of measures to mitigate the vulnerabilities.

Australia Releases Advisory on Password Spraying Attacks

The Australian Cyber Security Centre (ACSC) has released an advisory on password spraying attacks, noting it is aware of a high volume of such attacks targeting Australian organizations. Password spraying is a type of brute-force attack in which a malicious actor uses a single password against targeted user accounts before moving on to attempt a second password, and so on. This technique allows the actor to remain undetected by avoiding rapid or frequent account lockouts.
