The ABB Cylon FLXeon BACnet controller is vulnerable to authenticated remote root code execution via the /api/users/password endpoint. An attacker with valid credentials can inject arbitrary system commands by manipulating the newPassword PUT parameter. The issue arises in users.js, where the new password is hashed and improperly escaped before being passed to ChildProcess.exec() within a usermod command, allowing out of band (blind) command injection.

Organizations and development teams need to evolve from "being prepared" to "managing the risk" of security breaches.

The ABB Cylon FLXeon BACnet controller is vulnerable to authenticated remote root code execution via the /api/cert endpoint. An attacker with valid credentials can inject arbitrary system commands by manipulating the affected parameters. The issue arises due to improper input validation in cert.js, where user-supplied data is executed via ChildProcess.exec() without adequate sanitization.

In an attack vector that's been used before, threat actors aim to commit crypto fraud by hijacking highly followed users, thus reaching a broad audience of secondary victims.

When I joined Red Hat in 2019, one of the first blogs that I read was titled “Why CVSS does not equal risk: How to think about risk in your environment”. In summary, it explains why CVSS ≠ Risk: Common Vulnerability Scoring System (CVSS) scores measure the severity of vulnerabilities but don’t capture the unique risks they pose to specific environments. Risk is context-dependent, and organizations must consider factors like exploitability, impact and mitigation to tailor vulnerability management to their needs.Today, many organizations are still measuring the security of their environm

The ABB Cylon FLXeon BACnet controller is vulnerable to authenticated remote root code execution via the /api/timeConfig endpoint. An attacker with valid credentials can inject arbitrary system commands by manipulating parameters such as tz, timeServerYN, and multiple timeDate fields. The vulnerability exists due to improper input validation in timeConfig.js, where user-supplied data is executed via ChildProcess.exec() without adequate sanitization.

The ABB Cylon FLXeon BACnet controller is vulnerable to an authenticated root command injection. An attacker can exploit the Backup-Restore feature via the /api/upload endpoint to execute arbitrary system commands as root. The issue arises due to improper input validation in upload.js, where user-supplied input is passed to ChildProcess.exec() without adequate sanitization, allowing command injection via the filename parameter.

The ABB Cylon FLXeon BAS controller is vulnerable to authenticated root command execution via the cmds API. An authenticated attacker can execute arbitrary system commands with root privileges.

The ABB Cylon FLXeon (BACnet) controller suffers from an unauthenticated remote code execution vulnerability with root privileges. Input passed through the login.js script for the password JSON parameter allows out-of-band command injection.

This new report from Cisco Talos Incident Response explores how threat actors increasingly deployed web shells against vulnerable web applications, and exploited vulnerable or unpatched public-facing applications to gain initial access.
