CVE-2025-46157 is a remote code execution (RCE) vulnerability found in EfroTech Time Trax version 1.0, specifically within the file attachment functionality of the leave request form. This vulnerability allows a remote attacker to execute arbitrary code on the affected system by exploiting the file upload mechanism. The issue likely arises due to insufficient validation or sanitization of uploaded files, enabling malicious payloads to be executed on the server or client side. Since the vulnerability is triggered via the leave request form, it implies that an attacker can remotely interact with the application without requiring prior authentication or elevated privileges. The lack of a CVSS score and absence of known exploits in the wild suggest that this vulnerability is newly disclosed and not yet actively exploited. However, the potential for arbitrary code execution makes it a critical security concern. The vulnerability affects EfroTech Time Trax v1.0, a time management and leave request software solution, which is typically used by HR departments and employees to manage attendance and leave records. The exploitation of this vulnerability could lead to full system compromise, data theft, or disruption of business processes. Given the nature of the vulnerability, it is likely that the attack vector involves uploading a specially crafted file that bypasses security controls, leading to code execution on the server hosting the application or on connected systems. The absence of patches or mitigation details indicates that organizations using this software should urgently assess their exposure and apply compensating controls until an official fix is released.

For European organizations, the impact of CVE-2025-46157 can be significant, especially for those relying on EfroTech Time Trax for HR and attendance management. Successful exploitation could lead to unauthorized access to sensitive employee data, including personal identification information and leave records, potentially violating GDPR and other data protection regulations. Furthermore, arbitrary code execution could allow attackers to deploy ransomware, steal intellectual property, or move laterally within corporate networks, causing operational disruptions and financial losses. The vulnerability could also undermine trust in internal HR systems, affecting employee morale and organizational reputation. Since the vulnerability can be exploited remotely without authentication, it broadens the attack surface, increasing the risk of widespread compromise. Additionally, organizations in sectors with stringent compliance requirements, such as finance, healthcare, and government, may face severe regulatory penalties if exploited. The lack of known exploits currently provides a window for proactive defense, but the critical nature of RCE vulnerabilities necessitates immediate attention to prevent potential future attacks.

Given the absence of an official patch, European organizations should implement the following specific mitigation strategies: 1) Restrict access to the EfroTech Time Trax application by network segmentation and firewall rules, limiting exposure to trusted internal networks only. 2) Implement strict file upload controls, including disabling file attachments if feasible, or enforcing file type whitelisting and size restrictions. 3) Deploy web application firewalls (WAFs) with custom rules to detect and block malicious file upload patterns targeting the leave request form. 4) Conduct thorough input validation and sanitization on all file uploads at the application and server levels. 5) Monitor logs for unusual activity related to file uploads and leave request submissions, enabling early detection of exploitation attempts. 6) Educate HR and IT staff about the vulnerability and encourage prompt reporting of suspicious behavior. 7) Prepare incident response plans specifically addressing potential exploitation scenarios of this vulnerability. 8) Engage with EfroTech for updates on patches or official remediation guidance and plan for timely application once available. 9) Consider deploying endpoint detection and response (EDR) solutions to identify and contain any post-exploitation activities. These targeted measures go beyond generic advice by focusing on the specific attack vector and operational context of the affected software.
