- Company Headquarters Location: United States
Vulnerabilities
CVE-2018-19518
Fuel-Boss is vulnerable to the University of Washington IMAP Toolkit 2007f on UNIX, used in imap_open() in PHP and other products, launching an rsh command via the imap_rimap and tcp_aopen functions without preventing argument injection, which can allow remote attackers to execute arbitrary OS commands when an untrusted IMAP server name is supplied and rsh has been replaced by a program with different argument semantics such as ssh. This enables attacks through IMAP server names containing a “-oProxyCommand” argument, as well as a stack-based buffer overflow that may allow an attacker to remotely execute arbitrary code.

CVE-2019-11043
Fuel-Boss running versions up to and including PHP 7.1.5 is vulnerable because certain FPM configurations allow the FPM module to write past allocated buffers into space reserved for FCGI protocol data, thereby creating a possible remote code execution condition.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
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 cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
These vulnerabilities have a high attack complexity.
