CVE-2025-4807 is a medium-severity Exposure of Information Through Directory Listing (CWE-548) vulnerability in Senior-Walter Online Student Clearance System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A vulnerability classified as problematic has been identified in SourceCodester Online Student Clearance System version 1.0. The issue stems from exposure of information through directory listing, associated with CWE-548, CWE-552, and CWE-22, and can be triggered remotely without authentication by manipulating an unspecified component.
Unauthenticated remote attackers can exploit the flaw to enumerate directory contents and obtain sensitive information about the application's file structure. The CVSS 4.0 score of 6.9 reflects network attack vector, low complexity, and limited confidentiality impact with no integrity or availability effects.
Public references including a GitHub disclosure and Vuldb entries indicate the exploit has been made available, but no vendor advisories or patch details are referenced. The EPSS score remains flat at a low 0.0159 with no observed increase since publication.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly enforces authorization checks on access to files and directories, stopping unauthorized external exposure.
AC-6 limits granted privileges, reducing the chance that files or directories become reachable by external parties.
Requires secure baseline settings that disable directory listing on servers and file shares.
Restricts unnecessary server features such as automatic directory indexing.
Input validation directly neutralizes special path elements before pathname construction occurs.
Controls information flows so directory contents are not disclosed to unauthorized recipients.
Mitigating Controls (NIST CSF 2.0) AI
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.
Enforcing least-privilege permissions and authorization policies directly prevents unauthorized file/directory exposure.
Logical segmentation and access protections stop external parties from reaching files that should remain internal.
Hardened baselines and config management directly disable directory listing by default.
Lifecycle management includes applying secure configurations that would prevent directory exposure.
Vulnerability scanning can discover exposed directories so they can be remediated.
Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
Information access restriction directly prevents directory listings by enforcing need-to-know access controls on web resources.
Security testing in development and acceptance can detect and require remediation of exposed directory listings.
By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.
Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.
Including asset location and ownership in the inventory, combined with secure disposal procedures, decreases the chance that files or directories remain accessible to external parties after they should have been removed or restricted.
Solid perimeters and locked external access points stop files, devices, or directories containing sensitive data from being reachable by external parties who could otherwise walk in or break in.
