Some Huawei products RSE6500 V500R002C00; SoftCo V200R003C20SPCb00; VP9660 V600R006C10; eSpace U1981 V100R001C20; V200R003C20; V200R003C30; V200R003C50 have a weak algorithm vulnerability. To exploit the vulnerability, a remote, unauthenticated attacker has to capture TLS traffic between clients and the affected products. The attacker may launch the Bleichenbacher attack on RSA key exchange to decrypt the session key and the previously captured sessions by some cryptanalytic operations. Successful exploit may cause information leak.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.9, indicating it can be exploited remotely over the network but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 8 products from huawei, from huawei, from huawei and 5 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For huawei's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
