The ABB Cylon Aspect BMS/BAS controller is vulnerable to session fixation, allowing an attacker to set a predefined PHPSESSID value. An attacker can leverage an unauthenticated reflected XSS vulnerability in jsonProxy.php to inject a crafted request, forcing the victim to adopt a fixated session.

The ABB Cylon FLXeon BACnet controller is vulnerable to an authenticated JSON flooding attack, leading to uncontrolled resource consumption and a denial-of-service (DoS) condition. The /api/serialConfig endpoint allows an authenticated attacker to abuse an unrestricted loop to create a large number of JSON objects by sending specially crafted requests through the ports JSON array. This results in excessive memory and CPU usage, causing resource exhaustion and potential service failure.

The ABB Cylon FLXeon BACnet controller is vulnerable to an unauthenticated WebSocket implementation that allows an attacker to execute the tcpdump command. This command captures network traffic and filters it on serial ports 4855 and 4851, which are relevant to the device's services. The vulnerability can be exploited in a loop to start multiple instances of tcpdump, leading to resource exhaustion, denial of service (DoS) conditions, and potential data exfiltration. The lack of authentication on the WebSocket interface allows unauthorized users to continuously spawn new tcpdump processes, amplifying the attack's impact.

The application has a hidden administrative account 'cxpro' that has write access permissions to the device.

New research highlights how bad actors could abuse deleted AWS S3 buckets to create all sorts of mayhem, including a SolarWinds-style supply chain attack.

The North Korea-linked Lazarus Group has been linked to an active campaign that leverages fake LinkedIn job offers in the cryptocurrency and travel sectors to deliver malware capable of infecting Windows, macOS, and Linux operating systems. According to cybersecurity company Bitdefender, the scam begins with a message sent on a professional social media network, enticing them with the promise of

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.
