CVE-2025-14197 is an information disclosure vulnerability identified in Verysync, a file synchronization and web administration software, affecting versions 2.21.0 through 2.21.3. The vulnerability resides in an unspecified function within the Web Administration Module, specifically the REST API endpoint /rest/f/api/resources/f96956469e7be39d. This endpoint can be manipulated remotely by an unauthenticated attacker to disclose sensitive information. The exact nature of the disclosed information is not detailed, but such leaks typically include configuration data, user information, or system details that could facilitate further attacks. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with attack vector network (remote), low attack complexity, no privileges required, no user interaction, and limited confidentiality impact. The vendor was notified early but has not responded or provided a patch, and no known exploits have been observed in the wild yet. The public disclosure of the exploit increases the risk of exploitation, especially in environments where Verysync is exposed to untrusted networks. The lack of authentication and user interaction requirements makes this vulnerability easier to exploit compared to those requiring credentials or user actions. The vulnerability does not affect integrity or availability, limiting its impact to confidentiality breaches. The Web Administration Module is a critical component, and exposure of sensitive data could lead to further compromise if leveraged by attackers.

For European organizations, the primary impact is the unauthorized disclosure of sensitive information from the Verysync Web Administration Module. This could include configuration files, user credentials, or internal system information, which attackers could use to escalate privileges, move laterally, or conduct targeted attacks. Organizations relying on Verysync for file synchronization or administrative tasks may face increased risk of data breaches or espionage. The vulnerability’s remote and unauthenticated nature means attackers can exploit it without prior access, increasing exposure especially if the affected service is accessible from the internet or untrusted networks. While no integrity or availability impact is noted, the confidentiality breach could undermine trust, violate data protection regulations such as GDPR, and lead to financial or reputational damage. The absence of a vendor patch and public exploit disclosure heightens urgency for mitigation. Industries with sensitive data or critical infrastructure using Verysync are particularly vulnerable to targeted attacks leveraging this flaw.

1. Immediately restrict network access to the Verysync Web Administration Module, especially the /rest/f/api/resources/f96956469e7be39d endpoint, using firewalls or access control lists to limit exposure to trusted internal networks only. 2. Implement network segmentation to isolate Verysync servers from internet-facing systems and sensitive data repositories. 3. Monitor network traffic and logs for unusual or unauthorized access attempts targeting the vulnerable endpoint. 4. If possible, disable or restrict the vulnerable REST API functionality until a vendor patch is available. 5. Conduct thorough audits of Verysync configurations and user accounts to detect any signs of compromise. 6. Engage with the vendor for updates or patches and subscribe to vulnerability advisories for Verysync. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block exploitation attempts against the vulnerable endpoint. 8. Prepare incident response plans specific to information disclosure incidents involving Verysync. 9. Evaluate alternative secure file synchronization solutions if patching is delayed or vendor support remains absent. 10. Educate IT staff about this vulnerability and ensure rapid application of any future patches.
