Summary
CVE-2025-2494 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Sytel Softdial Contact Center. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-2494, published on 2025-03-18, is an unrestricted file upload vulnerability in Softdial Contact Center from Sytel Ltd. The flaw resides in the '/softdial/phpconsole/upload.php' endpoint, which is protected only by basic HTTP authentication but allows attackers to upload arbitrary files to a directory exposed by the web application. This can enable remote code execution, as the uploaded files may be executable within the server's environment.
Any remote attacker with network access can exploit this vulnerability without requiring privileges, user interaction, or special conditions, given its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). By uploading a malicious file such as a web shell, the attacker can achieve code execution on the server, potentially gaining full control over the affected system. The issue is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type).
The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-softdial-contact-center documents this as one of multiple vulnerabilities in Softdial Contact Center and provides related guidance.

V5.1.1
Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.
Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.
Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
