CVE-2020-9501 in Web P2P
Summary
by MITRE
Attackers can obtain Cloud Key information from the Dahua Web P2P control in specific ways. Cloud Key is used to authenticate the connection between the client tool and the platform. An attacker may use the leaked Cloud Key to impersonate the client to connect to the platform, resulting in additional consumption of platform server resources. Versions with Build time before April 2020 are affected.

The vulnerability identified as CVE-2020-9501 affects Dahua Web P2P control systems where attackers can extract Cloud Key information through specific exploitation techniques. This authentication mechanism represents a critical security flaw that undermines the integrity of client-platform communications within Dahua's ecosystem. The Cloud Key serves as the primary credential for establishing secure connections between client tools and the platform infrastructure, making its compromise particularly dangerous for maintaining system security and access control.
This vulnerability stems from improper handling of authentication credentials within the Dahua Web P2P control implementation, specifically exposing Cloud Key information that should remain confidential. The flaw allows attackers to obtain these credentials through methods that exploit weaknesses in the system's authentication architecture, creating opportunities for unauthorized access and impersonation attacks. The vulnerability is particularly concerning because it affects systems with build times prior to April 2020, indicating a widespread exposure across multiple deployments that may have been operational for extended periods without proper security updates.
The operational impact of this vulnerability extends beyond simple credential theft, as attackers can leverage the compromised Cloud Key to establish unauthorized connections to platform services. This unauthorized access results in additional consumption of platform server resources, potentially leading to performance degradation, resource exhaustion, and increased operational costs for affected organizations. The implications of such resource consumption can cascade through the platform infrastructure, affecting legitimate users and potentially creating denial-of-service conditions that impact business operations.
From a cybersecurity perspective, this vulnerability aligns with CWE-259 Weak Passwords and CWE-312 Cleartext Storage of Sensitive Information, representing multiple security weaknesses that together create a dangerous exposure for the affected systems. The attack pattern associated with this vulnerability can be categorized under ATT&CK technique T1078 Valid Accounts, as it involves the exploitation of legitimate authentication mechanisms through credential compromise. Organizations should implement immediate mitigations including patching affected systems, monitoring for unauthorized access attempts, and implementing additional authentication controls to prevent exploitation of this vulnerability.
The affected timeframe of build times before April 2020 indicates that this vulnerability has likely been present in production environments for considerable periods, potentially exposing organizations to prolonged risk without their knowledge. This long exposure period underscores the importance of regular security assessments and patch management processes that can identify and remediate such vulnerabilities before they can be exploited by threat actors. Security teams should prioritize identifying all affected systems within their infrastructure and implementing comprehensive monitoring to detect potential exploitation attempts that could leverage this Cloud Key exposure for unauthorized platform access.
