CVE-2024-41729 in NetWeaver BWinfo

Summary

by MITRE • 09/10/2024

Due to missing authorization checks, SAP BEx Analyzer allows an authenticated attacker to access information over the network which is otherwise restricted. On successful exploitation the attacker can enumerate information causing a limited impact on confidentiality of the application.

SAP BEx Analyzer represents a critical vulnerability in the enterprise business intelligence platform where insufficient authorization controls create a pathway for authenticated attackers to bypass security restrictions and access restricted network information. This vulnerability falls under the category of insufficient authorization checks, which is categorized as CWE-285 in the Common Weakness Enumeration framework. The flaw exists within the application's access control mechanisms, specifically within the network communication layer where proper authentication verification fails to occur before granting access to sensitive information resources.

The technical implementation of this vulnerability allows an attacker who has already established authentication credentials to exploit the missing authorization checks and enumerate information that should normally be restricted to authorized users only. This enumeration capability enables the attacker to discover and access data that would otherwise be protected by proper access controls, creating a limited but significant impact on the confidentiality aspect of the application's security posture. The vulnerability does not require elevated privileges beyond standard authentication, making it particularly dangerous as it can be exploited by users with legitimate access who may have broader information gathering capabilities than intended.

From an operational impact perspective, this vulnerability creates a risk of unauthorized information disclosure that could potentially expose sensitive business intelligence data, user access patterns, or system configurations that an attacker could leverage for further exploitation. The limited impact on confidentiality suggests that the vulnerability does not directly enable data modification or system compromise, but rather facilitates information gathering that could support more sophisticated attacks. This aligns with ATT&CK technique T1087.001 for account discovery and T1566.001 for credential access, as the vulnerability enables unauthorized information enumeration that could lead to privilege escalation or targeted attacks.

The exploitation of this vulnerability requires an authenticated user context, meaning that attackers must first obtain valid credentials before attempting to leverage the authorization bypass. This characteristic reduces the attack surface compared to vulnerabilities that allow anonymous access, but it still represents a significant risk within enterprise environments where credential compromise or insider threats could be exploited. Organizations should consider implementing additional monitoring controls to detect unusual enumeration patterns or unauthorized information access attempts that may indicate exploitation of this vulnerability. The remediation approach should focus on strengthening authorization controls within the BEx Analyzer component and ensuring proper access validation occurs before information disclosure.

Security teams should prioritize this vulnerability for remediation, particularly in environments where sensitive business intelligence data is processed or where the application serves as a gateway to other systems. The vulnerability demonstrates the importance of implementing defense-in-depth strategies that include proper authorization validation, network segmentation, and continuous monitoring of access patterns to detect anomalous behavior that may indicate exploitation attempts. Organizations should also consider implementing role-based access controls and regular security assessments to identify similar authorization gaps that could potentially be exploited to gain unauthorized access to restricted information resources.
