Summary
by MITRE
Huawei DP300 V500R002C00; TP3206 V100R002C00; ViewPoint 9030 V100R011C02; V100R011C03 have a use of a broken or risky cryptographic algorithm vulnerability. The software uses risky cryptographic algorithm in SSL. This is dangerous because a remote unauthenticated attacker could use well-known techniques to break the algorithm. Successful exploit could result in the exposure of sensitive information.

The vulnerability identified as CVE-2017-17167 affects several Huawei video conferencing and collaboration devices including the DP300 V500R002C00, TP3206 V100R002C00, and ViewPoint 9030 V100R011C02 and V100R011C03 models. This represents a critical weakness in the cryptographic implementation that undermines the security of secure communications established through these devices. The flaw specifically resides in the Secure Sockets Layer implementation where the software employs deprecated or insufficiently secure cryptographic algorithms that are vulnerable to well-documented attack techniques.
The technical nature of this vulnerability stems from the use of weak cryptographic primitives within the SSL/TLS protocol stack of these devices. When systems rely on outdated or broken cryptographic algorithms, they become susceptible to various attacks including man-in-the-middle scenarios, decryption of intercepted communications, and unauthorized access to sensitive data transmitted through these platforms. The risk is particularly severe because the vulnerability does not require authentication from the attacker, making it exploitable by remote unauthorized parties who can leverage known cryptographic weaknesses to compromise the system's security posture.
From an operational perspective, successful exploitation of this vulnerability could lead to the exposure of confidential information transmitted through the affected devices, potentially including proprietary communications, business-sensitive data, and personal information. The impact extends beyond simple data theft to encompass potential disruption of business continuity and compromise of enterprise security infrastructure. Organizations relying on these video conferencing solutions for critical communications may face significant security implications, particularly in regulated environments where data protection and privacy compliance are mandatory.
The vulnerability aligns with CWE-327, which addresses the use of a broken or risky cryptographic algorithm, and represents a clear violation of security best practices outlined in industry standards such as NIST SP 800-57 and ISO/IEC 15408. From an adversarial perspective, this weakness maps to ATT&CK technique T1566, which involves the use of social engineering to gain access to systems, as attackers could potentially exploit the cryptographic weakness to bypass security controls. The affected devices should be immediately isolated from critical networks and patched with available firmware updates from Huawei to remediate the cryptographic vulnerabilities and restore proper security controls.
Organizations should implement comprehensive network monitoring to detect any suspicious activities that might indicate exploitation attempts, while also conducting thorough risk assessments to determine the full scope of potential compromise. The remediation process requires careful attention to ensure that firmware updates do not disrupt existing video conferencing operations, and that proper change management procedures are followed to maintain service availability during the security patching process.
