SourceCodester Student Record Management System C++ V1.0 Stack-based Buffer Overflow

From this webpage screenshot, the following key information about the vulnerability can be obtained: 1. Vulnerability Description: - Title: SourceCodester Student Record Management System in C++ V1.0 Stack-based Buffer Overflow - Description: This student record management system project contains multiple stack-based buffer overflow vulnerabilities. In the main function, several features (such as "Add New Student" and "View All Student Grades") use fixed-size character arrays (e.g., and ) to store user input and file contents, without length checking. If the input or read data exceeds the array limits, a buffer overflow may occur, leading to memory corruption or illegal memory access. 2. Vulnerability Type: - Stack-based Buffer Overflow: Multiple features do not restrict the length of input read from or . 3. Vulnerability Details: - "Add New Student" Feature: Data is read via without length checking. If input exceeds 15 characters, it will overflow the buffer, potentially corrupting adjacent memory. - "View All Student Grades" Feature: The buffer is repeatedly filled without length checking. If file entries exceed 20 characters, it will write beyond the buffer, causing memory access errors. - "Update Student Grade" Feature: Multiple file write operations directly manipulate offsets without ensuring fixed data lengths. If file content exceeds expected length, it may write to unintended locations, causing data corruption. - Program Crash: Input or reading excessively large data may cause buffer overflow, resulting in memory access violations and program crashes. - Potential Arbitrary Code Execution: Attackers could use carefully crafted input to overwrite control flow data on the stack, potentially triggering code execution. - Data Corruption: Buffer overflow may corrupt adjacent memory locations, leading to unpredictable data or system instability. 4. Vulnerability Impact: - Code Execution: Malicious input or modification of data in may lead to code execution. - Data Corruption: Buffer overflow may cause data corruption, affecting system stability and data integrity. 5. Submission Information: - Submitter: polaris0x1 (UID 67906) - Submission Time: November 14, 2024, 09:40 AM (2 days ago) - Review Time: November 15, 2024, 03:28 PM (1 day after submission) - Status: Accepted This information provides a detailed description of the vulnerability's nature, impact, and submission details.
