CVE-2024-8957 affects PTZOptics PT30X-SDI/NDI-xx cameras prior to firmware version 6.3.40. This vulnerability allows an OS command injection issue due to insufficient validation of the ntp_addr configuration value. When the ntp_client is initiated, it could lead to arbitrary command execution. If exploited in conjunction with CVE-2024-8956, a remote and unauthenticated attacker can execute arbitrary OS commands on affected devices.
With a CVSS base score of 7.2, categorized as high severity, this vulnerability presents significant risks. The attack vector is network-based, requiring high privileges and making it relatively easy to exploit. Consequently, organizations must address this vulnerability promptly to prevent potential exploitation.
Risk to organizations includes potential unauthorized access and control over affected devices, which could lead to further exploitation or data breaches. Given its high severity and the likelihood of exploitation, organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits available for this vulnerability, but it is part of the Known Exploited Vulnerabilities (KEV) catalog. This status highlights the urgency for organizations to implement necessary mitigations or updates.
Vulnerability Details
The official CVE description states that 'PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an OS command injection issue.' The vulnerability type is classified as OS command injection, represented by CWE-78, indicating a lack of input validation in the ntp_addr configuration.
The CVSS score of 7.2 indicates a high severity, meaning organizations are at considerable risk if they do not mitigate this vulnerability. The affected product is PTZOptics PT30X-SDI/NDI cameras, and the vulnerability was published on September 17, 2024.
Technical Analysis
Root cause analysis indicates that the vulnerability arises from insufficient validation of user input, specifically the ntp_addr parameter. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is low, requiring high privileges, and no user interaction is needed to exploit the vulnerability.
The impact on confidentiality, integrity, and availability is rated as high, as an attacker could execute arbitrary OS commands, potentially compromising the entire device.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-8957 is significant. A successful exploit could lead to unauthorized control over PTZOptics cameras, potentially exposing sensitive information or enabling further attacks within the network. Organizations utilizing these cameras must consider the implications of a compromised device, which could have widespread effects on operational security.
Given the high CVSS score and current inclusion in the KEV catalog, organizations must treat this vulnerability with urgency. The potential for significant impact underscores the necessity of prioritizing remediation efforts.
Organizations should address this vulnerability in their next patch cycle. Engaging in proactive threat modeling can help identify potential attack vectors and strengthen defenses against such vulnerabilities.
