CVE-2025-67982 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the thembay Urna product up to version 2.5.12. The vulnerability enables Remote File Inclusion (RFI), a critical flaw where an attacker can manipulate the filename parameter used in PHP include or require statements to load and execute arbitrary remote PHP code. This occurs due to insufficient validation or sanitization of user-supplied input controlling the file path. The vulnerability does not require authentication or user interaction, and the attack vector is network-based, making exploitation feasible remotely. The CVSS v3.1 score of 8.1 reflects high impact on confidentiality, integrity, and availability, with a high attack complexity but no privileges or user interaction needed. Exploiting this vulnerability could allow attackers to execute arbitrary code on the server, leading to full system compromise, data theft, defacement, or service disruption. Although no public exploits are currently reported, the nature of RFI vulnerabilities historically makes them attractive targets. The vulnerability was reserved in December 2025 and published in February 2026, indicating recent discovery. The lack of available patches at the time of reporting necessitates immediate mitigation efforts by affected organizations.

The impact of CVE-2025-67982 is severe for organizations running thembay Urna versions up to 2.5.12. Successful exploitation allows remote attackers to execute arbitrary PHP code on the web server, potentially leading to full system compromise. This can result in unauthorized data access or exfiltration, defacement of websites, installation of backdoors or malware, and disruption of services. The breach of confidentiality, integrity, and availability can affect customer trust, lead to regulatory penalties, and cause financial losses. Since the vulnerability requires no authentication or user interaction, attackers can automate exploitation at scale, increasing risk. Organizations with public-facing web servers using the affected software are particularly vulnerable. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score indicates urgent attention is needed to prevent future attacks.

1. Apply official patches or updates from thembay as soon as they become available to address the vulnerability directly. 2. In the absence of patches, implement strict input validation and sanitization on all parameters controlling file inclusion paths to prevent injection of remote URLs or arbitrary file paths. 3. Configure PHP settings to disable allow_url_include and allow_url_fopen directives to prevent remote file inclusion. 4. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious include/require requests or attempts to inject remote URLs. 5. Restrict file inclusion paths using PHP's open_basedir directive to limit accessible directories. 6. Monitor web server logs for unusual requests targeting include/require parameters and investigate anomalies promptly. 7. Conduct regular security assessments and code reviews focusing on file inclusion mechanisms. 8. Educate development teams on secure coding practices related to dynamic file inclusion. 9. Isolate critical web applications in segmented network zones to limit lateral movement if compromise occurs.
