1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-9142 CISA Vulnerability Name: CVE-2024-9142 Description: The vulnerability involves an "External Control of File Name or Path" and "Incorrect Permission Assignment for Critical Resource" in Olgu Computer Systems e-Belediye. This flaw allows attackers to manipulate web input to file system calls, potentially leading to unauthorized access or modification of critical system files. CVSS Score: 9.8

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The CVSS score of 9.8 indicates a critical vulnerability with severe potential impacts. The high exploitability and impact scores suggest that this vulnerability can be easily exploited and can cause significant damage if left unaddressed.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Web Input Manipulation: Attackers can manipulate web inputs to inject malicious file names or paths.
2. Path Traversal: By exploiting the vulnerability, attackers can perform directory traversal attacks to access files outside the intended directory.
3. Privilege Escalation: Incorrect permission assignments can allow attackers to escalate privileges and gain unauthorized access to critical resources.

Exploitation Methods:

1. Injecting Malicious Inputs: Attackers can inject specially crafted file names or paths through web inputs to manipulate file system calls.
2. Accessing Sensitive Files: By exploiting the path traversal vulnerability, attackers can read or modify sensitive files, such as configuration files or system logs.
3. Executing Arbitrary Code: If the vulnerability allows for code execution, attackers can execute arbitrary code on the affected system, leading to complete system compromise.
