CVE-2024-34047 identifies a vulnerability in the O-RAN RIC I-Release e2mgr component, specifically within the RicServiceUpdateHandler function, which fails to perform adequate array size checks. This type of vulnerability typically leads to out-of-bounds memory access or buffer overflows, potentially causing data corruption or integrity violations. The O-RAN RIC (Radio Intelligent Controller) is a critical component in open RAN architectures, enabling intelligent control and management of radio access networks. The vulnerability allows an attacker with network access and low privileges to send crafted requests that exploit the lack of array bounds validation, leading to integrity issues in the service's internal data structures. The CVSS vector indicates no impact on confidentiality or availability, no user interaction required, and low attack complexity, but it requires privileges to access the network service. No known exploits have been reported yet, and no patches have been published, indicating this is a newly disclosed vulnerability. Given the specialized nature of O-RAN deployments, the vulnerability primarily affects telecom operators and vendors implementing open RAN solutions. The lack of array size checks is a common programming oversight that can be leveraged to disrupt normal operations or corrupt data, potentially impacting network management functions.

The primary impact of CVE-2024-34047 is on data integrity within the O-RAN RIC e2mgr component. Exploitation could lead to corrupted or manipulated data in the RicServiceUpdateHandler, potentially affecting the reliability of network control operations. While confidentiality and availability are not directly impacted, integrity issues in a critical network controller could indirectly degrade network performance or cause misconfigurations. Telecom operators relying on O-RAN RIC I-Release for network management may experience operational disruptions or degraded service quality if this vulnerability is exploited. The scope is limited to organizations deploying this specific open RAN software component, which is increasingly adopted in modern telecom networks aiming for vendor interoperability and flexibility. The absence of known exploits reduces immediate risk, but the vulnerability's presence in a critical telecom control plane component warrants proactive mitigation to prevent future exploitation. The medium CVSS score reflects moderate risk, balancing the limited impact scope with the ease of exploitation and network accessibility.

Organizations should monitor vendor advisories for patches addressing CVE-2024-34047 and apply them promptly once available. In the interim, implement strict input validation and sanitization on all data processed by the RicServiceUpdateHandler to prevent malformed requests from triggering the vulnerability. Restrict network access to the e2mgr service using network segmentation, firewalls, and access control lists to limit exposure to trusted entities only. Employ runtime application self-protection (RASP) or intrusion detection systems capable of detecting anomalous requests targeting the RicServiceUpdateHandler. Conduct thorough code reviews and static analysis on the O-RAN RIC software to identify and remediate similar array bounds issues. Additionally, maintain comprehensive logging and monitoring of the e2mgr component to detect potential exploitation attempts. Collaborate with O-RAN community and vendors to share threat intelligence and best practices for securing open RAN deployments.
