Cybersecurity researchers have uncovered an ongoing malvertising campaign that abuses Meta's advertising platform and hijacked Facebook accounts to distribute information known as SYS01stealer. "The hackers behind the campaign use trusted brands to expand their reach," Bitdefender Labs said in a report shared with The Hacker News. "The malvertising campaign leverages nearly a hundred malicious

This blog will demonstrate the practice and methodology of reversing BugSleep’s protocol, writing a functional C2 server, and detecting this traffic with Snort.

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to unauthorized project file disclosure. An unauthenticated remote attacker can issue a GET request abusing the DownloadProject servlet to download sensitive project files. The jsonProxy.php script bypasses authentication by proxying requests to localhost (AspectFT Automation Application Server), granting remote attackers unauthorized access to internal Java servlets. This exposes potentially sensitive project data and configuration details without requiring authentication.

The ABB BMS/BAS controller is vulnerable to remote, arbitrary servlet inclusion. The jsonProxy.php endpoint allows unauthenticated remote attackers to access internal services by proxying requests to localhost. This results in an authentication bypass, enabling attackers to interact with multiple java servlets without authorization, potentially exposing sensitive system functions and information.

The ABB BMS/BAS controller allows an unauthenticated attacker to disclose credentials in plain-text.

The ABB BMS/BAS controller suffers from an unauthenticated reflected cross-site scripting vulnerability. Input passed to the GET parameters 'query' and 'application' is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML/JS code in a user's browser session in context of an affected site.

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to unauthorized SSH service configuration changes. An unauthenticated attacker can enable or disable the SSH service on the server by accessing the FTControlServlet with the sshenable parameter. The jsonProxy.php script proxies requests to localhost without enforcing authentication, allowing attackers to modify SSH settings and potentially gain further unauthorized access to the system.

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to an unauthenticated Denial of Service (DoS) attack. An attacker can remotely restart the main Java server by accessing the FTControlServlet with the restart parameter. The endpoint proxies requests to localhost without requiring authentication, enabling attackers to disrupt system availability by repeatedly triggering server restarts.

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to username enumeration. An unauthenticated attacker can interact with the UserManager servlet to enumerate valid usernames on the system. Since jsonProxy.php proxies requests to internal services without requiring authentication, attackers can gain unauthorized insights into valid usernames.

The jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable to unauthorized information disclosure. An unauthenticated attacker can retrieve sensitive system information, including system time, uptime, memory usage, and network load statistics. The jsonProxy.php endpoint proxies these requests to internal services without requiring authentication, allowing attackers to obtain detailed system status data, which could aid in further attacks by revealing operational characteristics and resource utilization.
