Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-59895 is a remote denial-of-service (DoS) vulnerability in the configuration restore functionality of Sync Breeze Enterprise Server version 10.4.18 and Disk Pulse Enterprise version 10.4.18. The issue arises from insufficient validation of user-supplied data (CWE-20), allowing malicious input to corrupt the configuration file. Published on 2026-01-28, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high availability impact with no confidentiality or integrity effects.
An unauthenticated remote attacker can exploit this vulnerability by sending crafted requests over the network to the affected service. Successful exploitation alters the configuration file, rendering the application unresponsive and potentially preventing the service from restarting, even manually. Recovery may necessitate a complete reinstallation, as the corruption can make the service irrecoverable without intervention.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing input validation through analysis or test cases.
SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.
Requiring documented development standards and tools can embed input-validation practices into the engineering process.

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.
Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.
Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.
Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
