CVE-2025-46295 is a critical vulnerability found in Apache Commons Text library versions before 1.10.0, specifically impacting Claris FileMaker Server implementations that utilize this library for text interpolation. The vulnerability stems from unsafe interpolation features in the text-substitution API, which allow attackers to supply crafted untrusted input that is processed by interpolators capable of executing system commands or accessing external resources. This can lead to remote code execution (RCE) without requiring authentication or user interaction. The root cause relates to CWE-94 (Improper Control of Generation of Code), where input is improperly sanitized or validated before being executed or interpreted. The vulnerability affects all versions of FileMaker Server prior to 22.0.4, which includes the vulnerable Apache Commons Text versions. The CVSS v3.1 base score of 9.8 reflects the vulnerability's critical nature, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The scope is unchanged, but the impact on confidentiality, integrity, and availability is high, as attackers can execute arbitrary code remotely. Although no known exploits have been reported in the wild yet, the vulnerability's characteristics make it a prime target for attackers. The issue has been fully remediated in FileMaker Server 22.0.4 by updating the Apache Commons Text dependency and likely implementing stricter input validation and safer interpolation mechanisms.

The impact of CVE-2025-46295 is severe for organizations using vulnerable versions of Claris FileMaker Server. Successful exploitation allows remote attackers to execute arbitrary code on the server, potentially leading to full system compromise. This can result in unauthorized data access, data modification or deletion, disruption of services, and lateral movement within the network. Given FileMaker Server's role in managing databases and business-critical applications, exploitation could lead to significant operational downtime, data breaches, and loss of intellectual property. The vulnerability's ease of exploitation without authentication increases the risk of widespread attacks, especially in environments exposed to the internet. Organizations relying on FileMaker Server for sensitive or regulated data face compliance and reputational risks if exploited. Additionally, attackers could leverage this vulnerability to establish persistent access or deploy ransomware and other malware payloads.

To mitigate CVE-2025-46295, organizations should immediately upgrade Claris FileMaker Server to version 22.0.4 or later, where the vulnerability is fully addressed. If immediate upgrade is not feasible, restrict network access to FileMaker Server instances by implementing strict firewall rules and network segmentation to limit exposure. Review and sanitize all inputs passed to the text-substitution API to ensure untrusted data is never processed by vulnerable interpolation features. Employ application-layer controls to detect and block suspicious command execution attempts. Monitor server logs for unusual activity indicative of exploitation attempts. Additionally, consider deploying runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions to detect and prevent exploitation. Maintain an up-to-date inventory of software dependencies and apply security patches promptly. Educate developers and administrators about the risks of unsafe interpolation and the importance of secure coding practices.
