CVE-2025-4063 Overview
CVE-2025-4063 is a stack-based buffer overflow in code-projects Student Information Management System 1.0. The flaw resides in the cancel function, where manipulation of the first_name and last_name arguments corrupts stack memory. An authenticated local attacker can trigger the overflow to disrupt the application or potentially execute code within the process context. The exploit has been publicly disclosed, increasing the risk of opportunistic abuse against affected deployments. The weakness is tracked under CWE-119 and CWE-787.
Critical Impact
A local attacker supplying oversized first_name or last_name values to the cancel function can overwrite stack memory, causing application crashes or possible arbitrary code execution.

Technical Details for CVE-2025-4063
Vulnerability Analysis
The vulnerability is a stack-based buffer overflow inside the cancel function of the Student Information Management System. The function accepts first_name and last_name arguments without enforcing bounds against the destination stack buffers. Supplying inputs longer than the reserved buffer size causes adjacent stack memory, including saved return addresses and frame pointers, to be overwritten. The classification aligns with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-787 (Out-of-bounds Write).
Root Cause
The root cause is missing length validation on the first_name and last_name parameters before they are copied into fixed-size stack buffers inside cancel. Without input sanitization or safe string handling, the application relies on caller-supplied data to determine copy length. See the GitHub CVE Documentation for reproduction details.
Attack Vector
Exploitation requires local access and low-privileged authentication to the host running the application. The attacker invokes the vulnerable cancel code path with crafted first_name or last_name values that exceed the internal buffer. Successful exploitation compromises the confidentiality, integrity, and availability of the process at a limited scope. Because the attack is local and requires authentication, network-borne mass exploitation is not viable. Additional context is available in VulDB CTIID #306500 and VulDB #306500.
No verified proof-of-concept code is published beyond the disclosure notes. Refer to the GitHub CVE Documentation for technical reproduction steps.
Detection Methods for CVE-2025-4063
Indicators of Compromise
- Unexpected termination or segmentation faults in the Student Information Management System process during cancel operations.
- Presence of the vulnerable build (fabian:student_information_management_system:1.0) on internal hosts.
- Application logs recording abnormally long first_name or last_name values submitted to cancel workflows.
Detection Strategies
- Inventory local systems for installations of the Student Information Management System 1.0 codebase.
- Instrument the application with runtime memory safety tools such as AddressSanitizer during test builds to surface out-of-bounds writes.
- Review recent authentication logs for local user sessions that immediately preceded application crashes.
Monitoring Recommendations
- Forward application crash telemetry and Windows Error Reporting or core dump events to a centralized logging platform.
- Alert on repeated crashes of the Student Information Management System binary from the same local account.
- Monitor filesystem changes to the application directory that could indicate post-exploitation persistence.
How to Mitigate CVE-2025-4063
Immediate Actions Required
- Restrict local access to the application to trusted, authenticated administrators only.
- Disable or firewall the cancel workflow if it is not required for operations.
- Audit user accounts on hosts running the application and remove unnecessary local logins.
Patch Information
No vendor patch has been published in the referenced advisories at the time of NVD listing. Track updates on the Code Projects Resource and the VulDB Submission #559466 entry for remediation status. Where source code access is available, add explicit length checks and replace unsafe string copies with bounded functions such as strncpy_s or equivalent safe wrappers.
Workarounds
- Enforce input length validation at the front-end and API layers to reject oversized first_name and last_name values.
- Run the application with compiler-level protections including stack canaries, ASLR, and DEP to raise the exploitation bar.
- Isolate the application in a hardened, minimally privileged service account to limit blast radius from process compromise.
