Mitsubishi Electric Air Conditioning Systems
Use of a broken or risky cryptographic algorithm allows a remote unauthenticated attacker to cause a disclosure of an encrypted message from the air conditioning systems by sniffing encrypted communications.CVE-2022-24296 has been assigned to this vulnerability. A CVSS v3 base score of 3.1 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N). The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately 4 billion blocks. This which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode (a.k.a. a Sweet32 attack).CVE-2016-2183 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases that make it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions using the same plaintext.CVE-2013-2566 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). This vulnerability makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that relies on keys affected by the Invariance Weakness. An attacker can then use a brute-force approach involving LSB values (a.k.a. the Bar Mitzvah issue).CVE-2015-2808 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N). The TLS protocol and the SSL Protocol 3.0 and earlier do not properly associate renegotiation handshakes with an existing connection in some third-party products. This allows machine-in-the-middle attackers to insert data into sessions protected by TLS or SSL by sending an unauthenticated request processed retroactively by a server in a post-renegotiation context.CVE-2009-3555 has been assigned to this vulnerability. A CVSS v3 base score of 7.4 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H).
