CVE-2025-13771 is a relative path traversal vulnerability (CWE-23) found in Uniong's WebITR software, which allows authenticated remote attackers to read arbitrary files from the affected system. The vulnerability arises due to improper sanitization of file path inputs, enabling attackers to traverse directories and access files outside the intended directory scope. Since the attack vector is network-based (AV:N) and requires low attack complexity (AC:L) with no user interaction (UI:N), an attacker with valid credentials (PR:L) can exploit this flaw remotely without additional privileges or user involvement. The vulnerability impacts confidentiality (VC:H) but does not affect integrity or availability. The affected version is listed as '0', which likely refers to an initial or early release of WebITR. No patches or known exploits are currently available, but the vulnerability's presence in a web-facing application makes it a significant risk for data leakage. The CVSS 4.0 vector indicates no scope change and no additional privileges or user interaction needed, emphasizing the importance of credential security and input validation. The vulnerability was published on November 28, 2025, and assigned by TWCert. Organizations using WebITR should assess their exposure and implement mitigations promptly.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive information stored on systems running WebITR. Attackers with valid credentials can exploit the flaw to access configuration files, credentials, or other sensitive data, potentially leading to further compromise or data breaches. Critical sectors such as government, finance, healthcare, and industrial control systems that rely on WebITR for monitoring or management could face operational and reputational damage. The ability to remotely read arbitrary files without user interaction increases the attack surface, especially if credential theft or phishing enables initial access. Data privacy regulations like GDPR heighten the consequences of unauthorized data disclosure, potentially resulting in legal penalties and loss of customer trust. The lack of known exploits currently provides a window for proactive defense, but the high CVSS score indicates the need for urgent attention.

1. Implement strict input validation and sanitization on all file path parameters within WebITR to prevent directory traversal sequences such as '../'. 2. Restrict file access permissions on the server to limit the files accessible by the WebITR application user, minimizing the impact of arbitrary file reads. 3. Enforce strong authentication mechanisms and monitor for unusual login patterns to reduce the risk of credential compromise. 4. Employ network segmentation and firewall rules to limit access to WebITR interfaces to trusted networks and users only. 5. Conduct regular security audits and penetration testing focused on path traversal and file access vulnerabilities. 6. Monitor logs for suspicious file access attempts and implement alerting for potential exploitation indicators. 7. Coordinate with Uniong for timely patches or updates and apply them as soon as they become available. 8. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting WebITR.
