CVE-2026-41993 in SafePortAgent
Summary
by MITRE • 07/17/2026
Improper Access Control vulnerability in the Removable Media Validation function of TXOne Networks products allows a local attacker with administrator privileges to bypass the file lockdown mechanism, resulting in unauthorized file transfer to the victim device. The attacker needs to deploy unauthorized file on the removable media in advance. This issue affects SafePortAgent: before 3.2.5024; StellarProtect: from 3.2.4011 before 5.0.1083.

This vulnerability represents a critical improper access control flaw within the removable media validation mechanisms of TXOne Networks products, specifically affecting the SafePortAgent and StellarProtect software solutions. The issue stems from inadequate validation of removable media content during file transfer operations, creating a pathway for malicious actors to circumvent established security controls. The vulnerability requires local administrator privileges to exploit, indicating that it operates within an already compromised environment where the attacker has elevated system access. This represents a significant escalation risk as it allows attackers who have already gained administrative access to bypass additional security layers designed to prevent unauthorized file transfers between systems.
The technical implementation flaw manifests in how the Removable Media Validation function processes and validates file content prior to allowing transfer operations. When an attacker with administrator privileges places malicious files on removable media, the system fails to properly validate these files against established security policies and lockdown mechanisms. The validation process appears to rely on insufficient checks that do not adequately verify file integrity or source authenticity before permitting transfer operations. This creates a scenario where legitimate security controls designed to prevent unauthorized data exfiltration or infiltration are effectively bypassed through manipulation of the removable media validation routine.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it enables attackers to perform unauthorized file transfers that could facilitate further compromise of target systems. The ability to bypass file lockdown mechanisms represents a serious threat to data protection policies and security controls within enterprise environments where such products are deployed. Attackers can leverage this vulnerability to deploy malware, steal sensitive information, or establish persistent access points on victim devices through the bypassed transfer mechanisms. This issue particularly affects organizations using TXOne Networks solutions for secure file transfer operations, potentially undermining their entire security infrastructure.
The affected product versions demonstrate a clear pattern of vulnerability persistence across different software releases, with SafePortAgent requiring updates beyond version 3.2.5024 and StellarProtect needing upgrades from version 3.2.4011 to address the issue before version 5.0.1083. This indicates that the vulnerability has been present for an extended period, potentially allowing attackers to exploit it for prolonged periods without detection. The vulnerability classification aligns with CWE-284, which addresses improper access control in software systems, and represents a specific implementation failure where authorization controls are bypassed through inadequate validation of removable media content. From an attack framework perspective, this vulnerability maps to ATT&CK technique T1074.001 for data staging and potentially T1566 for initial compromise through removable media.
Mitigation strategies should focus on immediate deployment of the vendor-provided patches for both SafePortAgent and StellarProtect products, while also implementing additional monitoring controls around removable media usage and file transfer operations. Organizations should conduct comprehensive vulnerability assessments to identify systems running affected versions and implement network segmentation to limit potential lateral movement if exploitation occurs. Additional security measures including enhanced logging of file transfer activities, implementation of endpoint detection and response solutions, and regular security audits of removable media policies can help detect and prevent exploitation attempts. The remediation process should also include reviewing and strengthening existing access control policies to ensure that administrator privileges are properly managed and that least privilege principles are enforced across all systems utilizing these products.
