Assignment On Software Vulnerabilities

Question

Assignment On Software Vulnerabilitysoftware Vulnerabilities Especial Analyze two software vulnerabilities from reputable sources, such as the CWE Top 25 and OWASP Top 10 lists. For each vulnerability, explain its nature, where it occurs (e.g., programming language, application type), provide an example attack that exploited it, and discuss methods for minimizing, preventing, or mitigating the vulnerability. Your explanation should be in your own words, and you may include code snippets to illustrate the vulnerability or its mitigation. The report should not exceed two double-spaced pages per vulnerability. You must consult at least two references for each vulnerability. Additionally, reflect briefly on the OWASP Top 10 – 2018 and the 2018 CWE/SANS Top 25 lists, discussing their focus areas and differences. Proper citations are expected throughout your report.

Software vulnerabilities pose significant security threats in modern computing environments, often arising from programming flaws, logical errors, or systemic weaknesses within applications. Among the numerous identified vulnerabilities, buffer overflow and cross-site scripting (XSS) are two prominent examples from recognized frameworks—the CWE Top 25 and OWASP Top 10 lists, respectively. This report explores these vulnerabilities, their occurrence, exploitation, and preventative measures. 1. Buffer Overflow Vulnerability Description and Occurrence: Buffer overflow is a prevalent vulnerability typically found in languages like C and C++, where manual memory management is required. It occurs when a program writes more data to a buffer (a contiguous block of memory) than it can hold, overwriting adjacent memory locations. This overflow can corrupt data, crash programs, or be exploited to execute arbitrary code. The vulnerability arises mainly due to inadequate bounds checking during data copying routines such as strcpy(), sprintf(), or user input handling. Example Attack: An attacker exploits a buffer overflow by sending an input longer than the buffer size in a vulnerable program, causing the overwriting of the return address on the stack. This allows the attacker to redirect execution flow to malicious shellcode injected into the buffer, potentially gaining control of the system—commonly seen in classic stack buffer overflow exploits targeting vulnerable C applications. Mitigation Strategies: Implement proper bounds checking in code to prevent writing beyond buffer limits. Use safer functions such as strncpy(), strlcpy(), or snprintf() that limit the number of bytes copied. Utilize compiler protections like Stack Canaries, ASLR (Address Space Layout Randomization), and DEP (Data Execution Prevention). Apply code auditing and static analysis tools to identify vulnerable code segments. References: CWE-120: Buffer Copy without Checking Size ('Buffer Overflow') – MITRE
