CVE-2022-30560 is classified as a high-severity vulnerability with a CVSS score of 7.4. It affects multiple DahuaSecurity IPC firmware versions. An attacker who obtains administrative credentials or executes a man-in-the-middle attack can exploit this vulnerability by sending specially crafted packets to the vulnerable interface, leading to a device crash. The risk to organizations includes potential downtime and disruption of services, making this a critical issue to address.
Organizations should prioritize patching immediately to prevent exploitation. The vulnerability was published on June 28, 2022, and has been marked as modified, indicating updates may have been made to the vulnerability's details or remediation status.
As of now, there are no public exploits confirmed for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for exploitation remains a concern, especially in environments utilizing the affected DahuaSecurity products.
The urgency for defenders to act cannot be overstated, given the implications of device crashes in operational settings. Immediate attention to remediation measures is advised.
Vulnerability Details
The official description of CVE-2022-30560 states: 'When an attacker obtaining the administrative account and password, or through a man-in-the-middle attack, the attacker could send a specified crafted packet to the vulnerable interface then lead the device to crash.' This vulnerability is classified under the attack vector 'NETWORK' with high complexity, indicating that a skilled attacker may be required to exploit it effectively.
The CVSS v3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H, which reflects a high impact on confidentiality and availability, while integrity is not affected. The affected DahuaSecurity components include various IPC firmware versions, particularly those released before April 2022.
Technical Analysis
The root cause of this vulnerability is associated with insufficient validation of packets sent to the device. This oversight allows an attacker to manipulate the network traffic, potentially leading to a denial of service condition by causing the device to crash.
The attack vector is categorized as network, with high attack complexity, meaning that while exploitation is possible, it requires a knowledgeable attacker. No privileges are required, and user interaction is not necessary, which increases the risk profile of this vulnerability.
Regarding impact, the vulnerability has high confidentiality impact, as it could lead to unauthorized access to sensitive information, and high availability impact, as it could cause the device to crash and become unusable. Integrity impact is assessed as none.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-30560 is significant, especially for organizations that rely on DahuaSecurity products for critical operations. The potential for device crashes can lead to service interruptions, impacting customer satisfaction and operational efficiency.
The blast radius for this vulnerability can be substantial, affecting not only individual devices but potentially entire networks if exploited effectively. Organizations must assess their exposure to ensure that all vulnerable devices are identified and remediated.
Given the CVSS score of 7.4 and the lack of mitigation measures available, organizations should address this vulnerability in their priority patch cycle. Prompt action is essential to minimize risks.
