CVE-2021-33544 identifies a high-severity vulnerability affecting multiple camera devices by Geutebrück and other vendors. This vulnerability allows command injection, enabling attackers to remotely execute arbitrary code. The CVSS score of 7.2 highlights the critical nature of this vulnerability, necessitating urgent attention from organizations utilizing affected devices.
With an attack vector classified as network-based and low complexity, attackers can exploit this vulnerability with minimal effort, particularly given that high privileges are required to execute commands. The potential for unauthorized access and control over camera functionality underscores the need for immediate remediation.
Currently, there are no public exploits confirmed for this vulnerability, but its presence in multiple firmware versions raises concerns about widespread impact. Organizations should prioritize patching affected devices to mitigate risks associated with this vulnerability.
Organizations should address this vulnerability promptly as part of their security posture. Failure to do so may result in severe consequences, including compromised surveillance integrity and unauthorized access.
Vulnerability Details
The official description notes that multiple camera devices by UDP Technology, Geutebrück, and other vendors are susceptible to command injection. This vulnerability affects several firmware versions across multiple product lines, including the g-cam_ebc, g-cam_efd, and g-cam_ethc series. The vulnerability is classified under CWE-78, indicating a command injection flaw.
The CVSS score of 7.2 denotes a high severity level, indicating substantial risk to confidentiality, integrity, and availability. Affected systems include g-cam_ebc-2110, g-cam_ebc-2111, g-cam_efd-2241, and more, with a publication date of September 13, 2021.
Technical Analysis
The root cause of this vulnerability is improper input validation, which enables command injection through specially crafted requests. The attack vector is primarily network-based, allowing remote exploitation without user interaction. Attack complexity is low, and an attacker requires high privileges to execute code, amplifying the potential risk.
The impacts on confidentiality, integrity, and availability are significant, with high potential for data exposure and service disruption. Organizations must be vigilant regarding system configurations and network protections to mitigate this vulnerability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access and remote code execution, which could lead to surveillance system manipulation or data breaches. The blast radius for this vulnerability is considerable, affecting various camera models across different deployments. Given the CVSS score and the potential for exploitation, organizations should prioritize remediation in their patch cycle.
With an EPSS score of 0.942, this vulnerability is in the highest risk percentile, indicating a strong likelihood of exploitation in the wild. Organizations must take immediate action to patch vulnerable firmware to prevent possible exploitation.
In summary, the urgency for patching is critical. Organizations should incorporate this vulnerability into their risk management strategies and conduct thorough assessments of their camera systems.
