CVE-2018-0662 in TS-WRLP
Summary
by MITRE
Multiple I-O DATA network camera products (TS-WRLP firmware Ver.1.09.04 and earlier, TS-WRLA firmware Ver.1.09.04 and earlier, TS-WRLP/E firmware Ver.1.09.04 and earlier) allow an attacker on the same network segment to add malicious files on the device and execute arbitrary code.

The vulnerability identified as CVE-2018-0662 affects multiple I-O DATA network camera models including TS-WRLP, TS-WRLA, and TS-WRLP/E devices running firmware versions 1.09.04 and earlier. This represents a critical security flaw that allows local network attackers to execute arbitrary code on affected devices through a malicious file upload process. The vulnerability stems from insufficient input validation and inadequate file handling mechanisms within the camera's firmware, creating a pathway for privilege escalation and unauthorized system control.
The technical implementation of this vulnerability involves a lack of proper file type verification and sanitization during the upload process. Attackers can exploit this weakness by crafting malicious files that bypass the device's security checks, ultimately leading to code execution with elevated privileges. This flaw aligns with CWE-434 which describes insecure file upload vulnerabilities where systems accept files without proper validation, and represents a direct violation of secure coding practices. The attack vector requires network proximity, making it a local privilege escalation vulnerability that could be leveraged by attackers within the same network segment.
The operational impact of CVE-2018-0662 extends beyond simple code execution, as compromised cameras can serve as entry points for broader network infiltration. Once an attacker gains control of a network camera, they can potentially access the entire network segment, capture video feeds, manipulate device settings, or use the compromised device as a pivot point for attacking other systems. This vulnerability directly maps to ATT&CK technique T1059.007 for command and scripting interpreter, and T1071.004 for application layer protocol, as attackers can leverage the compromised device to execute commands and establish persistent access. The implications are particularly severe for surveillance environments where camera security is paramount.
Mitigation strategies for this vulnerability should include immediate firmware updates from I-O DATA to address the underlying file handling flaws. Network segmentation and access control measures can help limit the attack surface, while implementing network monitoring to detect suspicious file upload activities. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in networked devices. The vulnerability highlights the importance of secure firmware development practices and proper input validation, as outlined in OWASP Top Ten and NIST cybersecurity guidelines. Organizations should also consider implementing network access controls such as 802.1X authentication and firewall rules to restrict unauthorized access to network camera devices and prevent exploitation of similar vulnerabilities in the future.
