CVE-2025-0124 in Cloud NGFW
Summary
by MITRE • 04/11/2025
An authenticated file deletion vulnerability in the Palo Alto Networks PAN-OS® software enables an authenticated attacker with network access to the management web interface to delete certain files as the “nobody” user; this includes limited logs and configuration files but does not include system files.
The attacker must have network access to the management web interface to exploit this issue. You greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended critical deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
This issue affects Cloud NGFW. However, this issue does not affect Prisma® Access software.

The vulnerability identified as CVE-2025-0124 represents a significant authenticated file deletion flaw within Palo Alto Networks PAN-OS software that operates at the intersection of privilege escalation and file system manipulation. This weakness specifically targets the management web interface of the platform, creating a scenario where authenticated users with network access can leverage their credentials to perform unauthorized file deletion operations. The vulnerability is particularly concerning because it allows attackers to remove critical operational files including logs and configuration data, while maintaining operational security boundaries that prevent access to core system files. The technical implementation appears to involve insufficient access controls or validation mechanisms within the file management subsystem of the web interface, which fails to properly enforce user permissions when processing file deletion requests. This represents a direct violation of the principle of least privilege and demonstrates inadequate separation of concerns between different user roles and system functions. The vulnerability's impact is constrained to specific file types but remains significant due to the potential for operational disruption and forensic data loss that could compromise incident response capabilities and security monitoring effectiveness.
The operational implications of this vulnerability extend beyond simple file deletion to encompass broader security posture degradation and potential operational disruption within network security environments. When an attacker successfully exploits this weakness, they can remove audit logs that would normally provide visibility into security events, configuration files that maintain system integrity, and other operational artifacts that support network security operations. This creates a scenario where security teams may lose critical forensic evidence, making it difficult to investigate security incidents or understand the true state of their network environment. The ability to delete logs specifically targets the organization's security monitoring capabilities and could be used to cover malicious activities or obscure the true impact of security incidents. The vulnerability's scope excludes system files, suggesting that the underlying access control mechanisms properly distinguish between operational files and core system components, but this protection is insufficient to prevent the deletion of critical operational data that supports security operations and compliance requirements. This aligns with CWE-276, which addresses inadequate file permissions and improper file access control, and demonstrates how insufficient access control can lead to operational security degradation.
The exploitation of this vulnerability requires an authenticated user with network access to the management web interface, which provides a clear attack surface and mitigation pathway. Organizations can significantly reduce risk by implementing strict network access controls that limit management interface access to trusted internal IP addresses, as recommended by Palo Alto Networks deployment guidelines. This approach aligns with the ATT&CK framework's concept of network segmentation and access control, specifically addressing techniques related to privilege escalation and defense evasion. The restriction of management interface access represents a fundamental security control that addresses the initial access requirement for exploitation, effectively reducing the attack surface to only authorized personnel within trusted network segments. However, the vulnerability's presence in Cloud NGFW implementations suggests that organizations must maintain continuous vigilance regarding cloud-based security platform configurations and ensure that proper access controls are maintained across all deployment environments. The fact that this vulnerability does not affect Prisma Access software indicates that the implementation differences between these platforms may provide additional security controls or access restrictions that prevent exploitation of this specific weakness, though similar vulnerabilities may exist in other components of the broader Palo Alto Networks security ecosystem.
The mitigation strategies for this vulnerability should focus on implementing comprehensive access control measures including network segmentation, multi-factor authentication, and regular security audits of management interface access. Organizations should consider implementing additional logging and monitoring specifically for management interface activities, particularly file operations, to detect unauthorized access attempts or successful exploitation. The recommended restriction of management interface access to trusted internal IP addresses serves as the primary defense mechanism and aligns with industry best practices for securing management interfaces. This vulnerability highlights the importance of maintaining robust access control policies and demonstrates how even authenticated access can be leveraged to cause significant operational damage when proper access controls are not implemented. Regular security assessments should include verification of file system permissions and access controls within management interfaces to prevent similar issues from arising in other components of the security infrastructure. The vulnerability serves as a reminder that management interfaces, while necessary for system administration, represent critical attack surfaces that require rigorous security controls and continuous monitoring to prevent unauthorized access and exploitation.
