CVE-2017-17106 in PR115-204-P-RS
Summary
by MITRE
Credentials for Zivif PR115-204-P-RS V2.3.4.2103 Webcams can be obtained by an unauthenticated remote attacker using a standard web /cgi-bin/hi3510/param.cgi?cmd=getuser HTTP request. This vulnerability exists because of a lack of authentication checks in requests to CGI pages.

The CVE-2017-17106 vulnerability represents a critical security flaw in Zivif PR115-204-P-RS V2.3.4.2103 webcams that exposes sensitive authentication credentials to unauthenticated remote attackers. This vulnerability specifically affects the device's web interface implementation and demonstrates a fundamental failure in access control mechanisms. The issue stems from the absence of proper authentication verification when processing requests to the /cgi-bin/hi3510/param.cgi endpoint, allowing any remote attacker to retrieve user credentials simply by sending a standard HTTP GET request with the command parameter set to getuser. This flaw essentially provides an open door for unauthorized access to the device's authentication system, bypassing all security measures that should normally protect credential information.
The technical nature of this vulnerability aligns with CWE-287, which addresses improper authentication issues in software systems. This weakness creates a direct path for attackers to escalate their privileges and gain unauthorized access to the webcam's administrative functions. The vulnerability exists within the CGI (Common Gateway Interface) implementation where the device fails to verify the authenticity of incoming requests before responding with sensitive user information. The attack vector is particularly concerning because it requires no prior authentication credentials, making it accessible to anyone who can reach the device's network address. The exploitation process involves sending a simple HTTP request to the vulnerable endpoint, which then returns the user credentials without any verification of the requester's authorization status.
From an operational perspective, this vulnerability poses significant risks to network security and privacy. Once an attacker obtains valid credentials, they can assume full administrative control over the affected webcam devices, potentially enabling them to modify device configurations, access live video feeds, change user permissions, or even use the devices as entry points for further network attacks. The impact extends beyond individual device compromise, as these webcams are often deployed in security monitoring environments where unauthorized access could lead to complete surveillance system breaches. The vulnerability also creates opportunities for attackers to use compromised devices for botnet formation, DDoS attacks, or as pivoting points for accessing other network resources. This type of vulnerability is particularly dangerous in enterprise environments where multiple devices may be deployed across different locations, creating a potential attack surface that could be exploited to gain access to entire network infrastructures.
The mitigation strategies for CVE-2017-17106 should focus on immediate remediation efforts including firmware updates from the vendor, network segmentation to isolate affected devices, and implementation of network access controls to restrict access to the vulnerable CGI endpoints. Organizations should also consider disabling unnecessary web services and implementing strong authentication mechanisms for any remaining access points. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and privilege escalation, specifically targeting the T1078 (Valid Accounts) and T1566 (Phishing) tactics. Regular security assessments and network monitoring should be implemented to detect potential exploitation attempts, while incident response procedures should be established to address any confirmed compromises. The vulnerability also highlights the importance of secure coding practices and proper authentication implementation in embedded systems, emphasizing that even simple devices require robust security controls to prevent unauthorized access to sensitive information.
