Server-Side Request Forgery (SSRF)
The primary vulnerability (CVE-2024-47578) is an SSRF flaw that enables attackers with administrative privileges to send specially crafted requests from vulnerable web applications.
This could potentially lead to unauthorized access to internal systems typically protected by firewalls.
File Upload And Download Exploits
CVE-2024-47579 allows authenticated attackers with administrative rights to exploit a web service for uploading or downloading custom PDF font files on the system server.
This vulnerability could be used to access any file on the server without affecting system integrity.
PDF Attachment Manipulation
CVE-2024-47580 permits authenticated attackers to create PDFs with embedded attachments, specifying internal server files as attachments.
This could lead to unauthorized access to sensitive files on the server.
The exploitation of these vulnerabilities could result in:
- Data breaches exposing confidential business information
- Unauthorized access to intellectual property and personal data
- Potential for lateral movement within internal networks
- Compromised system integrity and availability
- Regulatory non-compliance and associated penalties
Mitigation Steps
SAP urges customers to apply Security Note 3536965 immediately to address these vulnerabilities. Key mitigation steps include:
