Security Vulnerabilities
Apache ActiveMQ does not properly validate the remaining length field which may lead to an overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT control packets which makes the broker susceptible to unexpected behavior when interacting with non-compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts Remaining Length to a maximum of 4 bytes. The scenario occurs on established connections after the authentication process. Brokers that are not enabling mqtt transport connectors are not impacted.
This issue affects Apache ActiveMQ: before 5.19.2, 6.0.0 to 6.1.8, and 6.2.0
Users are recommended to upgrade to version 5.19.2, 6.1.9, or 6.2.1, which fixes the issue.

SFX2100 Satellite Receiver, trivial password for the `user` (usr) account. A remote unauthenticated attacker can exploit this to gain unauthorized SSH access to the system, while intially dropped into a restricted shell, an attacker can trivially spawn a complete pty to gain an appropriately interactive shell.

International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver contains undocumented, hardcoded/insecure credentials for the `xd` user account. A remote unauthenticated attacker can log in via FTP using these credentials. Because the `xd` user has write permissions to their home directory where root-executed binaries and symlinks (such as those invoked by `xdstartstop`) are stored, the attacker can overwrite these files or manipulate symlinks to achieve arbitrary code execution as the root user.

International Datacasting Corporation (IDC) SFX Series SuperFlex(SFX2100) SatelliteReceiver contains hardcoded and insecure credentials for the `admin` account. A remote unauthenticated attacker can use these undocumented credentials to access the satellite system directly via the Telnet service, leading to potential system compromise.

The /root/anaconda-ks.cfg installation configuration file in International Datacasting Corporation (IDC) SFX Series(SFX2100) SuperFlex Satellite Receiver insecurely stores the hardcoded root password hash. The password itself is highly insecure and susceptible to offline dictionary attacks using the rockyou.txt wordlist. Because direct root SSH login is disabled, an attacker must first obtain low-privileged access to the system (e.g., via other vulnerabilities) to be able to log in as the root user. The password is hardcoded and so allows for an actor with local access on effected versions to escalate to root

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the /index.cgi endpoint of International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web Management Interface version 101. The application fails to adequately sanitize user-supplied input provided via the `cat` parameter before reflecting it in the HTTP response, allowing a remote attacker to execute arbitrary HTML or JavaScript in the victim's browser context.

A Reflected Cross-Site Scripting (XSS) vulnerability in the /IDC_Logging/index.cgi endpoint of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface version 101 allows a remote attacker to execute arbitrary web scripts or HTML. The vulnerability is triggered by sending a crafted payload through the `submitType` parameter, which is reflected directly into the DOM without proper escaping.

The web-based Ping diagnostic utility (/IDC_Ping/main.cgi) in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web Management Interface version 101 is vulnerable to OS Command Injection. The application insecurely parses the `IPaddr` parameter. An authenticated attacker can bypass server-side semicolon exclusion checks by using alternate shell metacharacters (such as the pipe `|` operator) to append and execute arbitrary shell commands with root privileges.

An OS Command Injection vulnerability exists in the web-based Traceroute diagnostic utility of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface version 101. An authenticated attacker can inject arbitrary shell metacharacters (such as the pipe `|` operator) into the flags parameter, leading to the execution of arbitrary operating system commands with root privileges.

An unauthenticated Remote Code Execution (RCE) vulnerability exists in the SNMP service of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver. The deployment insecurely provisions the `private` SNMP community string with read/write access by default. Because the SNMP agent runs as root, an unauthenticated remote attacker can utilize `NET-SNMP-EXTEND-MIB` directives, abusing the fact that the system runs a vulnerable version of net-snmp pre 5.8, to execute arbitrary operating system commands with root privileges.
