Vulnerability Details
The vulnerability allows unauthenticated attackers in the SAP NetWeaver AS Java Logon application, specifically version 7.50, to perform brute force attacks on the login functionality. This action can lead to the identification of legitimate user IDs. The CVSS score of this vulnerability is 5.3, categorized as medium severity due to its potential impact on confidentiality.
The specific affected product is "netweaver_application_server_java" by SAP. The vulnerability was published on November 14, 2023, and is classified under CWE-307, indicating improper authentication.
Technical Analysis
The root cause of CVE-2023-42480 is the inadequate protection of the login mechanism within the NetWeaver AS Java Logon application. Attackers can exploit this weakness by leveraging automated tools to brute force user IDs without requiring any privileges or user interaction.
The attack vector for this vulnerability is network-based, characterized by low attack complexity. No privileges are required for an attacker, and user interaction is not needed to exploit this vulnerability. The impact on confidentiality is low, as attackers can only identify user IDs without gaining further access.
Risk & Impact Analysis
The real-world risk associated with this vulnerability includes the possibility of unauthorized access attempts against the identified user accounts. If successful, such attacks can lead to further exploitation of the system and compromise sensitive information.
Organizations must recognize the urgency to address this vulnerability, considering its potential impact on user confidentiality and the broader security posture of their systems. With a CVSS score of 5.3, it falls within the medium severity range, prompting a medium priority for remediation.
Given the nature of brute force attacks, the blast radius can be significant if multiple accounts are targeted. Therefore, organizations should implement robust monitoring and response strategies to mitigate the risk of unauthorized access.
