Summary
PHOENIX CONTACT: FL MGUARD affected by two vulnerabilities
Notes
Summary: The FL MGUARD family of devices is affected by two vulnerabilities.
Impact: CVE-2022-4304: The OpenSSL library contains a bug that leads to a timing oracle when RSA based ciphers are used without forward secrecy for network communication. By sending a very large number of trial messages, an attacker can try to achieve a decryption of encrypted network packets. This affects TLS connections to and from the FL MGUARD as well as VPN connections. The highest risk arises from deferred attempts to decrypt pre-recorded network sessions. The throttling feature of the FL MGUARD can impede but not prevent the attack.There is a risk that attackers could decrypt network traffic encrypted by the FL MGUARD device. CVE-2023-2673: If a FL MGUARD or TC MGUARD device is operated in static or autodetect stealth mode, UDP packets which are directed to the protected device do not pass the configured MAC filter rules. The issue does not compromise the incoming IPv4 packet filter, which blocks all incoming traffic by default. The issue does not affect multi stealth mode.There is a risk that attackers could send UDP packets to the protected device which should have been filtered out.
Mitigation: Do not use RSA based ciphers for encryption of network traffic, use cipher suites with forward secrecy for TLS or IPsec communication and renew vulnerable certificates frequently. Configure the incoming IPv4 packet filter carefully to protect clients from potentially malicious UDP packets.
Remediation: The vulnerabilities are fixed in firmware versions 8.9.1 and 10.2.0. We strongly recommend all affected FL MGUARD users to upgrade to this or a later version.
CVE-2022-4304

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.

5.9 (Medium)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
CWE-203 - Observable Discrepancy
Mitigation Do not use RSA based ciphers for encryption of network traffic, use cipher suites with forward secrecy for TLS or IPsec communication and renew vulnerable certificates frequently. Configure the incoming IPv4 packet filter carefully to protect clients from potentially malicious UDP packets.
Vendor Fix The vulnerabilities are fixed in firmware versions 8.9.1 and 10.2.0. We strongly recommend all affected FL MGUARD users to upgrade to this or a later version.
CVE-2023-2673

Improper Input Validation vulnerability in PHOENIX CONTACT FL/TC MGUARD Family in multiple versions may allow UDP packets to bypass the filter rules and access the solely connected device behind the MGUARD which can be used for flooding attacks.

5.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
CWE-1287 - Improper Validation of Specified Type of Input
Mitigation Do not use RSA based ciphers for encryption of network traffic, use cipher suites with forward secrecy for TLS or IPsec communication and renew vulnerable certificates frequently. Configure the incoming IPv4 packet filter carefully to protect clients from potentially malicious UDP packets.
Vendor Fix The vulnerabilities are fixed in firmware versions 8.9.1 and 10.2.0. We strongly recommend all affected FL MGUARD users to upgrade to this or a later version.

          "text": "A timing based side channel exists in the OpenSSL RSA Decryption implementation\nwhich could be sufficient to recover a plaintext across a network in a\nBleichenbacher style attack. To achieve a successful decryption an attacker\nwould have to be able to send a very large number of trial messages for\ndecryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5,\nRSA-OEAP and RSASVE.\n\nFor example, in a TLS connection, RSA is commonly used by a client to send an\nencrypted pre-master secret to the server. An attacker that had observed a\ngenuine connection between a client and a server could use this flaw to send\ntrial messages to the server and record the time taken to process them. After a\nsufficiently large number of messages the attacker could recover the pre-master\nsecret used for the original connection and thus be able to decrypt the\napplication data sent over that connection.",
