Vulnerability Details
The vulnerability allows a remote attacker to cause a denial of service in Open5GS v2.7.3 through a crafted PDU Session Modification Request. The official CVE description highlights this issue, emphasizing its impact on service availability.
The CVSS score of 7.5 categorizes this as high severity, where the attack vector is network-based, the attack complexity is low, and no privileges or user interaction are required. The availability impact is rated as high, which is critical for organizations relying on the affected service.
Technical Analysis
The root cause of this vulnerability stems from improper handling of requests, which allows an attacker to send crafted requests that the system fails to process correctly, leading to a denial of service. The attack vector is network-based, meaning it can be exploited remotely without needing physical access to the system.
Attack complexity is low, as attackers do not need special skills or sophisticated techniques to exploit the vulnerability. Additionally, no privileges or user interactions are required, making it easier for attackers to initiate the denial of service.
The impacts on confidentiality and integrity are rated as none, but the availability impact is high, which is a significant concern for organizations dependent on the services provided by Open5GS.
Risk & Impact Analysis
Organizations using Open5GS v2.7.3 are at risk of service disruptions due to this vulnerability. The denial of service can affect not only the immediate services provided but also customer trust and satisfaction. The potential blast radius is significant, as it can impact multiple users and systems relying on this service.
Given the high CVSS score, organizations should assess their risk levels and prioritize remediation efforts accordingly. The vulnerability is currently deferred, which indicates that active exploitation has not been reported, but the potential for future exploitation exists.
Organizations should implement monitoring mechanisms to detect any unusual activities that might indicate an attempt to exploit this vulnerability. Urgency for patching remains high due to the potential impact on service availability.
