CVE-2025-29865: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in TAGFREE X-Free Uploader
: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in TAGFREE X-Free Uploader XFU allows Path Traversal.This issue affects X-Free Uploader: from 1.0.1.0084 before 1.0.1.0085, from 2.0.1.0034 before 2.0.1.0035.
AI Analysis
Technical Summary
CVE-2025-29865 is a high-severity path traversal vulnerability (CWE-22) found in TAGFREE's X-Free Uploader software versions 1.0.1.0084 and 2.0.1.0034, affecting all versions prior to 1.0.1.0085 and 2.0.1.0035 respectively. This vulnerability arises from improper limitation of a pathname to a restricted directory, allowing an attacker to craft malicious file paths that traverse outside the intended upload directory. By exploiting this flaw, an unauthenticated remote attacker can potentially access or overwrite arbitrary files on the server hosting the X-Free Uploader without any user interaction. The CVSS 4.0 base score of 8.7 reflects its network attack vector, low complexity, no privileges or user interaction required, and high impact on confidentiality due to unauthorized file access. The vulnerability does not affect integrity or availability directly but poses a significant risk of data exposure or unauthorized file manipulation. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability was reserved in March 2025 and published in August 2025, indicating recent discovery and disclosure. The lack of patch links suggests that organizations using affected versions should prioritize mitigation and monitoring until updates are available. The vulnerability is critical in environments where X-Free Uploader is used to handle sensitive or critical file uploads, as attackers could leverage path traversal to access configuration files, credentials, or other sensitive data stored on the server.
Potential Impact
For European organizations, the impact of CVE-2025-29865 can be significant, especially for those relying on TAGFREE's X-Free Uploader for file management or web applications. Unauthorized access to sensitive files could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Confidentiality breaches could expose intellectual property, customer data, or internal configurations, increasing the risk of further attacks such as lateral movement or privilege escalation. Since the vulnerability requires no authentication or user interaction, it can be exploited remotely by attackers scanning for vulnerable instances, increasing the attack surface. Organizations in sectors such as finance, healthcare, government, and critical infrastructure in Europe are particularly at risk due to the sensitivity of their data and regulatory requirements. Additionally, the ability to overwrite files could allow attackers to implant backdoors or malware, leading to persistent compromise. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score indicates that exploitation would be impactful and relatively straightforward once exploit code becomes available.
Mitigation Recommendations
European organizations should immediately inventory their use of TAGFREE X-Free Uploader and identify affected versions (1.0.1.0084 and 2.0.1.0034). Until official patches are released, organizations should implement strict input validation and sanitization on file upload paths to prevent directory traversal sequences (e.g., '..\' or '../'). Deploy web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting the uploader endpoints. Restrict file system permissions for the uploader process to the minimum necessary directories, preventing access to sensitive areas even if traversal is attempted. Monitor logs for suspicious file access patterns or unexpected file modifications. Network segmentation can limit exposure by isolating servers running the uploader from broader internal networks. Organizations should subscribe to TAGFREE security advisories for timely patch releases and apply updates promptly. Additionally, conducting penetration testing focused on file upload functionalities can help identify residual vulnerabilities. Employing intrusion detection systems (IDS) with signatures for path traversal attacks can provide early warnings. Finally, consider alternative secure file upload solutions if immediate patching is not feasible.
