CVE-2025-4068: Simple Movie Ticket Booking Buffer Overflow

CVE-2025-4068 Overview

CVE-2025-4068 is a stack-based buffer overflow vulnerability in code-projects Simple Movie Ticket Booking System 1.0. The flaw resides in the changeprize function, where the prize argument is copied without proper bounds checking. An attacker with local access and low privileges can trigger memory corruption by supplying an oversized value to this parameter. The exploit has been publicly disclosed, though no active in-the-wild exploitation has been reported.

Critical Impact
Local attackers can corrupt stack memory in the changeprize function, potentially leading to application crashes or arbitrary code execution within the process context.

Technical Details for CVE-2025-4068

Vulnerability Analysis

The vulnerability is a stack-based buffer overflow classified under [CWE-121] and out-of-bounds write [CWE-787], with a broader mapping to improper restriction of operations within memory buffer bounds [CWE-119]. The flaw is located in the changeprize function of Simple Movie Ticket Booking System 1.0. When the function processes the prize argument, it writes user-controlled input into a fixed-size stack buffer without validating input length.

Successful exploitation can corrupt adjacent stack memory, including saved return addresses and local variables. This corruption can crash the application or, depending on compiler protections and layout, allow an attacker to redirect execution flow. The attack requires local access, which limits mass exploitation but remains a risk in shared environments or when combined with other flaws.

Root Cause

The root cause is the absence of bounds checking when copying the prize argument into a fixed-size stack buffer inside changeprize. The application does not enforce a maximum input length or use safe string handling routines, allowing overlong input to overwrite memory beyond the buffer boundary.

Attack Vector

The attack vector is local. An attacker must have the ability to execute the vulnerable application and supply crafted input to the changeprize function. The attack complexity is low, and only limited privileges are required. Because the exploit has been disclosed publicly through GitHub CVE documentation and VulDB references, threat actors can reproduce the condition without additional research.

A synthetic proof-of-concept has not been verified for this article. Refer to the GitHub CVE Documentation and VulDB #306505 Analysis for technical detail on triggering the overflow.

Detection Methods for CVE-2025-4068

Indicators of Compromise

Unexpected crashes or segmentation faults tied to the Simple Movie Ticket Booking System process.
Core dumps containing overwritten return addresses or corrupted stack frames referencing the changeprize function.
Presence of Simple Movie Ticket Booking System 1.0 binaries in production or shared multi-user environments.

Detection Strategies

Monitor process telemetry for abnormal termination signals (SIGSEGV, SIGABRT) originating from the vulnerable binary.
Deploy runtime memory protections and enable stack canary reporting to surface overflow attempts.
Correlate local user activity with process crash events on hosts running the affected application.

Monitoring Recommendations

Log invocations of the Simple Movie Ticket Booking System application, including command-line arguments and user context.
Track write access to source directories or binaries associated with simple_movie_ticket_booking_system.
Alert on repeated crashes of the same process by the same user within a short time window, which suggests exploitation attempts.

How to Mitigate CVE-2025-4068

Immediate Actions Required

Remove Simple Movie Ticket Booking System 1.0 from production or shared systems until a fix is available.
Restrict local access to the application to trusted users only, and audit existing accounts.
Isolate hosts running the application from sensitive data or privileged network segments.

Patch Information

No vendor advisory or official patch has been published for CVE-2025-4068 at the time of writing. The project is distributed through the Code Projects Resource Hub, which hosts the affected application. Organizations should track the VulDB #306505 Details page for update notifications and consider replacing the application with a maintained alternative.

Workarounds

Recompile the application with modern stack protections (-fstack-protector-strong, ASLR, non-executable stack) if source access is available.
Apply input length validation at the wrapper or launcher script level before invoking the vulnerable binary.
Run the application inside a restricted sandbox or container to limit the blast radius of a successful overflow.
Disable or uninstall the application in environments where it is not business-critical.

bash

# Configuration example: restrict execution to a dedicated low-privilege user
sudo chown root:ticketapp /usr/local/bin/movie_ticket_booking
sudo chmod 750 /usr/local/bin/movie_ticket_booking
# Enforce resource limits to contain crashes
echo 'ticketapp hard core 0' | sudo tee -a /etc/security/limits.conf
