To exploit the vulnerability, a remote, unauthenticated attacker has to capture traffic between clients and the affected products. The attacker may launch the Bleichenbacher attack on RSA key exchange and decrypt the session key by some cryptanalytic operations and the previously captured TLS sessions. Successful exploit may cause information leak. (Vulnerability ID: HWPSIRT-2017-12135)This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2017-17174.Huawei has released software updates to fix this vulnerability.
