GarrettCom Magnum 6K and 10K managed switches contain an authentication bypass vulnerability that allows unauthenticated attackers to gain unauthorized access by exploiting a hardcoded string in the authentication mechanism. Attackers can bypass login controls to access administrative functions and sensitive switch configuration without valid credentials.

Hirschmann HiLCOS products OpenBAT, BAT450, WLC, BAT867 contains a firewall filtering vulnerability that fails to correctly filter IPv4 multicast and broadcast traffic when management IP address filtering is disabled, allowing configured filter rules to be bypassed. Attackers with network access can inject or observe multicast and broadcast packets that should have been blocked by the firewall.

Hirschmann HiOS and HiSecOS products RSP, RSPE, RSPS, RSPL, MSP, EES, EESX, GRS, OS, RED, EAGLE contain an authentication bypass vulnerability in the HTTP(S) management module that allows unauthenticated remote attackers to gain administrative access by crafting specially formed HTTP requests. Attackers can exploit improper authentication handling to obtain the authentication status and privileges of a previously authenticated user without providing valid credentials.

Hirschmann HiLCOS OpenBAT and BAT450 products contain a firewall bypass vulnerability in IPv6 IPsec deployments that allows traffic from VPN connections to bypass configured firewall rules. Attackers can exploit this vulnerability by establishing IPv6 IPsec connections (IKEv1 or IKEv2) while simultaneously using an IPv6 Internet connection to circumvent firewall policy enforcement.

Hirschmann Industrial HiVision versions 06.0.00 and 07.0.00 prior to 06.0.06 and 07.0.01 contains an improper authorization vulnerability that allows read-only users to gain write access to managed devices by bypassing access control mechanisms. Attackers can exploit alternative interfaces such as the web interface or SNMP browser to modify device configurations despite having restricted permissions.

Hirschmann HiLCOS Classic Platform switches Classic L2E, L2P, L3E, L3P versions prior to 09.0.06 and Classic L2B prior to 05.3.07 contain a credential exposure vulnerability where user passwords are synchronized with SNMPv1/v2 community strings and transmitted in plaintext when the feature is enabled. Attackers with local network access can sniff SNMP traffic or extract configuration data to recover plaintext credentials and gain unauthorized administrative access to the switches.

Hirschmann HiLCOS devices OpenBAT, WLC, BAT300, BAT54 prior to 8.80 and OpenBAT prior to 9.10 are shipped with identical default SSH and SSL keys that cannot be changed, allowing unauthenticated remote attackers to decrypt or intercept encrypted management communications. Attackers can perform man-in-the-middle attacks, impersonate devices, and expose sensitive information by leveraging the shared default cryptographic keys across multiple devices.

Hirschmann HiSecOS devices versions prior to 05.3.03 contain a buffer overflow vulnerability in the HTTPS login interface when RADIUS authentication is enabled that allows remote attackers to crash the device or execute arbitrary code by submitting a password longer than 128 characters. Attackers can exploit improper bounds checking in password handling to overflow a fixed-size buffer and achieve denial of service or remote code execution.

Hirschmann Industrial HiVision versions prior to 06.0.07 and 07.0.03 contains an authentication bypass vulnerability in the master service that allows unauthenticated remote attackers to execute arbitrary commands with administrative privileges. Attackers can invoke exposed interface methods over the remote service to bypass authentication and achieve remote code execution on the underlying operating system.

Hirschmann HiOS devices versions prior to 08.1.00 and 07.1.01 contain a denial of service vulnerability in the EtherNet/IP stack where improper handling of packet length fields allows remote attackers to crash or hang the device. Attackers can send specially crafted UDP EtherNet/IP packets with a length value larger than the actual packet size to render the device inoperable.

Hirschmann Industrial HiVision version 08.1.03 prior to 08.1.04 and 08.2.00 contains a vulnerability in the execution of user-configured external applications that allows a local attacker to execute arbitrary binaries. Due to insufficient path sanitization, an attacker can place a malicious binary in the execution path of a configured external application, causing it to be executed instead of the intended application. This can result in execution with elevated privileges depending on the context of the external application.

Hirschmann EagleSDV version 05.4.01 prior to 05.4.02 contains a denial-of-service vulnerability that causes the device to crash during session establishment when using TLS 1.0 or TLS 1.1. Attackers can trigger a crash by initiating TLS connections with these protocol versions to disrupt service availability.

Hirschmann Industrial IT products (BAT-R, BAT-F, BAT450-F, BAT867-R, BAT867-F, WLC, BAT Controller Virtual) contain a heap overflow vulnerability in the HiLCOS web interface that allows unauthenticated remote attackers to trigger a denial-of-service condition by sending specially crafted requests to the web interface. Attackers can exploit this heap overflow to crash the affected device and cause service disruption, particularly in configurations where the Public Spot functionality is enabled.

HiOS Switch Platform versions 09.1.00 prior to 09.4.05 and 10.3.01 contains a denial-of-service vulnerability in the web interface that allows remote attackers to reboot the affected device by sending a malicious HTTP GET request to a specific endpoint. Attackers can trigger an uncontrolled reboot condition through crafted HTTP requests to cause service disruption and unavailability of the switch.

Hirschmann HiEOS devices versions prior to 01.1.00 contain an authentication bypass vulnerability in the HTTP(S) management module that allows unauthenticated remote attackers to gain administrative access by sending specially crafted HTTP(S) requests. Attackers can exploit improper authentication handling to obtain elevated privileges and perform unauthorized actions including configuration download or upload and firmware modification.

HiSecOS web server versions 05.0.00 to 08.3.01 prior to 08.3.02 contains a privilege escalation vulnerability that allows authenticated users with operator or auditor roles to escalate privileges to the administrator role by sending specially crafted packets to the web server. Attackers can exploit this flaw to gain full administrative access to the affected device.

HiSecOS web server versions 03.4.00 prior to 04.1.00 contains a privilege escalation vulnerability that allows authenticated users with operator or auditor roles to escalate privileges to the administrator role by sending specially crafted packets to the web server. Attackers can exploit this flaw to gain full administrative access to the affected device.

HiSecOS 04.0.01 contains a privilege escalation vulnerability that allows authenticated users to modify their access role through XML-based NETCONF configuration. Attackers can send crafted XML payloads to the /mops_data endpoint with a specific role value to elevate their user privileges to administrative level.
