CVE-2025-8239: Critical SQL Injection Vulnerability in Exam Form Submission 1.0
A critical vulnerability has been identified in Exam Form Submission 1.0, potentially allowing attackers to execute arbitrary SQL commands on the underlying database. This could lead to data breaches, modification, or even complete system compromise.
Vulnerability Details
- CVE ID: CVE-2025-8239
- Description: An SQL injection vulnerability exists in the /admin/ interface of Exam Form Submission 1.0. By manipulating the 'email' parameter, an attacker can inject malicious SQL code.
- CVSS Score: 7.3 (HIGH)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
- CVSS Explanation: This vulnerability is remotely exploitable (AV:N) with low complexity (AC:L) and doesn't require any privileges (PR:N) or user interaction (UI:N). The impact is limited to partial confidentiality (C:L), integrity (I:L), and availability (A:L). This means an attacker could read sensitive data, modify existing data, or cause limited disruption to the service.
- Exploit Requirements: No authentication is required to exploit this vulnerability. An attacker simply needs to send a crafted request to the vulnerable endpoint.
- Affected Vendor: code-projects
- Affected Product: Exam Form Submission
- Affected Version: 1.0
- CWE: CWE-89 (SQL Injection) - This weakness occurs when an application incorporates untrusted data into an SQL query without proper sanitization. This allows attackers to inject arbitrary SQL code, potentially compromising the database.
Timeline of Events
- 2025-07-27: Vulnerability reported and CVE ID assigned.
- 2025-07-27: Proof-of-concept exploit publicly disclosed.
Exploitability & Real-World Risk
The existence of a public proof-of-concept significantly increases the risk associated with this vulnerability. Attackers can readily use the exploit code to target vulnerable installations. Due to the sensitive nature of data often stored in exam submission systems (student details, grades, etc.), successful exploitation could lead to significant data breaches and privacy violations. This vulnerability could be chained with other vulnerabilities to achieve a more significant impact.
Recommendations
- Apply the Patch: Upgrade to a patched version of Exam Form Submission as soon as it becomes available.
- Input Sanitization: Implement robust input sanitization and validation for all user-supplied data, especially the 'email' parameter.
- Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks.
- Web Application Firewall (WAF): Deploy a WAF with rules to detect and block SQL injection attempts.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities proactively.
Technical Insight
The vulnerability stems from the lack of proper sanitization of the 'email' parameter when constructing the SQL query. This allows an attacker to inject malicious SQL code into the query, which is then executed by the database server. For example, an attacker could use a payload like ' OR '1'='1 to bypass authentication or extract sensitive data.
