Technical Analysis

CVE-2023-5553 is a high-severity vulnerability identified in AXIS OS, the operating system used by Axis Communications AB in their network video products. The vulnerability is classified under CWE-863, which pertains to incorrect authorization. Specifically, the flaw affects the Secure Boot mechanism designed to protect devices from tampering by ensuring that only authorized and verified firmware and software components are loaded during the boot process. During an internal threat modeling exercise under the Axis Security Development Model (ASDM), this flaw was discovered, revealing that an attacker could potentially bypass Secure Boot protections. This bypass could allow unauthorized code execution or firmware modification, compromising the device's integrity and security. The affected versions range from AXIS OS 10.8 through 11.6. Although no known exploits have been reported in the wild to date, the vulnerability is rated with a CVSS 3.1 score of 7.6, indicating a high level of risk. The CVSS vector (AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) shows that the attack requires physical access (AV:P), has low complexity (AC:L), requires no privileges (PR:N) or user interaction (UI:N), and impacts confidentiality, integrity, and availability with a changed scope (S:C). This means an attacker with physical access could fully compromise the device, leading to complete control over the system and potentially the network it is connected to. Axis Communications has released patched versions of AXIS OS to address this vulnerability, emphasizing the importance of updating affected devices promptly.

Potential Impact

For European organizations, the impact of CVE-2023-5553 is significant, especially for those relying on Axis network video products for security surveillance and monitoring. Successful exploitation could allow attackers to bypass Secure Boot protections, leading to unauthorized firmware modifications or code execution. This compromises the confidentiality, integrity, and availability of the surveillance systems, potentially allowing attackers to disable cameras, manipulate video feeds, or use compromised devices as entry points into broader network infrastructures. Given the critical role of video surveillance in public safety, critical infrastructure protection, and corporate security across Europe, such a compromise could have cascading effects including physical security breaches, data exfiltration, and disruption of security operations. The requirement for physical access limits remote exploitation but raises concerns in environments where devices are deployed in less secure or publicly accessible locations. The changed scope in the CVSS vector indicates that the attacker can affect components beyond the initially vulnerable device, potentially impacting connected systems and networks. Therefore, the vulnerability poses a high risk to organizations in sectors such as transportation, government, utilities, and large enterprises that utilize Axis devices extensively.

Mitigation Recommendations

To mitigate the risks posed by CVE-2023-5553, European organizations should take the following specific actions: 1) Immediately identify all Axis devices running AXIS OS versions 10.8 through 11.6 within their environment. 2) Apply the official patches released by Axis Communications without delay to ensure the Secure Boot bypass flaw is remediated. 3) Implement strict physical security controls around devices, especially those installed in publicly accessible or unsecured locations, to prevent unauthorized physical access that could enable exploitation. 4) Employ network segmentation to isolate Axis devices from critical network segments, limiting the potential lateral movement if a device is compromised. 5) Monitor device logs and network traffic for signs of tampering or unusual activity that could indicate attempts to exploit the vulnerability. 6) Establish a regular update and patch management process for all IoT and networked security devices to reduce exposure to known vulnerabilities. 7) Consider deploying additional security layers such as endpoint detection and response (EDR) solutions that can detect anomalous behavior on devices. These measures go beyond generic advice by focusing on physical security, patch prioritization, and network architecture adjustments tailored to the nature of this vulnerability.
