The remote host has been identified as a RuggedCom server prior to v2.13.0, and is therefore affected by multiple vulnerabilities in the included Quagga package :

 - The Quagga BGP daemon used to double-free memory when processing certain forms of UPDATE messages. This issue could be exploited by sending an optional/transitive UPDATE attribute that all conforming eBGP speakers should pass along. Consequently, a single UPDATE message could have affected many bgpd processes across a wide area of a network. Through this vulnerability, attackers could potentially have taken over control of affected bgpd processes remotely. (CVE-2018-5379)
 - It was possible to overrun internal BGP code-to-string conversion tables in the Quagga BGP daemon. Configured peers could have exploited this issue and cause bgpd to emit debug and warning messages into the logs that would contained arbitrary bytes. (CVE-2018-5380)
 - The Quagga BGP daemon could have entered an infinite loop if sent an invalid OPEN message by a configured peer. If this issue was exploited, then bgpd would cease to respond to any other events. BGP sessions would have been dropped and not be reestablished. The CLI interface would have been unresponsive. The bgpd daemon would have stayed in this state until restarted. (CVE-2018-5381)

The remote device is running SIMOCODE Pro V EIP prior to version 1.0.2, and is therefore affected by a vulnerability that could allow remote attackers to conduct a DoS attack by sending specially crafted packets to port 161/udp (SNMP).

Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source, this may lead to a denial-of-service condition. An application that calls DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a denial-of-service attack. DH_generate_key() and DH_check_pub_key() are also called by a number of other OpenSSL functions. Also vulnerable are the OpenSSL pkey command line application when using the '-pubcheck' option, as well as the OpenSSL genpkey command line application. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

Specially crafted network packets sent to affected devices on port 4840/tcp could allow an unauthenticated remote attacker to cause a denial of service condition of the OPC communication or crash the device. The security vulnerability could be exploited by an attacker with network access to the affected systems.
Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the OPC communication.

The webserver of the affected devices contains a vulnerability that may lead to a denial of service condition. An attacker may cause a denial of service situation which leads to a restart of the webserver of the affected device. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the device.
