CVE-2020-1810Network attack vector

Information disclosure via weak RSA key exchange

Published Jan 9, 2020 · Updated Aug 4, 2024

Weak cryptography in Huawei network products allows remote attackers with network access to disclose information through SSL key exchange. The SSL key-exchange configuration selects RSA, which Huawei identifies as weak, but the advisory does not disclose the cryptanalytic method or exposed data. Network reachability is required; the documented consequence is limited to unspecified information disclosure, with no integrity or availability impact.
