CVE-2026-65311 in HIPASE-250
Summary
by MITRE • 07/31/2026
The HTTP server component of ANDRITZ HIPASE-250 (formerly 250 SCALA) in affected versions exposes an undocumented endpoint that changes the server's logging level and target without requiring authentication. A remote, unauthenticated attacker with network access to the service may suppress audit logging, potentially concealing other activity on the system.

This vulnerability exists within the HTTP server component of ANDRITZ HIPASE-250 (formerly 250 SCALA) systems where an undocumented administrative endpoint allows modification of server logging configuration without authentication requirements. The flaw represents a critical security weakness that directly violates fundamental principles of access control and system integrity. The exposed endpoint enables unauthorized parties to alter the logging level and destination parameters, effectively compromising the system's ability to maintain proper audit trails.
The technical implementation of this vulnerability stems from inadequate authentication mechanisms within the HTTP server component. This issue aligns with CWE-287 which addresses improper authentication scenarios where systems fail to properly verify user identity before granting administrative privileges. The absence of proper authorization checks means that any remote attacker with network connectivity to the service can manipulate logging configurations regardless of their credentials or role within the system. This represents a classic case of insecure direct object reference vulnerability where sensitive system functions are accessible through predictable endpoint paths.
From an operational perspective, this vulnerability creates significant risk for security monitoring and incident response capabilities. When audit logging is suppressed, malicious actors can effectively erase traces of their activities within the system, making detection and forensic analysis considerably more difficult. The impact extends beyond simple log manipulation as it undermines the foundational security principle of defense in depth where multiple layers of protection should work together to detect and prevent unauthorized access. This vulnerability directly enables persistent threats to operate undetected while maintaining their presence within the target environment.
The threat landscape for this vulnerability is particularly concerning given that it requires no authentication credentials to exploit, making it accessible to any attacker who can establish network connectivity to the affected service. Attackers could leverage this capability to hide other malicious activities such as unauthorized data access, privilege escalation attempts, or system compromise operations. This aligns with ATT&CK technique T1562.006 which covers "Impair Command History Logging" and represents a critical step in maintaining persistence while avoiding detection. The vulnerability essentially provides an attacker with a backdoor mechanism to disable security controls that would otherwise alert administrators to suspicious activities.
Mitigation strategies should focus on implementing proper authentication and authorization controls for all administrative endpoints. Systems administrators should immediately implement network segmentation to restrict access to the affected service only to authorized personnel and trusted networks. Additionally, comprehensive monitoring should be deployed to detect unusual logging configuration changes, and regular security assessments should verify that no unauthorized endpoints exist within the system. The implementation of principle of least privilege access controls and regular security audits would help prevent similar vulnerabilities from emerging in other components of the system architecture.
