Security readout for executives and security teams
Plain-English summary
CVE-2020-37057 is a high-severity SQL injection issue in Online-Exam-System 2015. An attacker could abuse the feedback module’s fid parameter to interfere with database queries, potentially exposing or changing data. Treat this as urgent if the product is internet-facing or stores student, exam, or administrative records.
Executive priority
Prioritize remediation for any internet-facing or production deployment. The business concern is unauthorized access to or alteration of exam-related database records. If the application is unused, retirement is likely the fastest risk reduction path.
Technical view
The issue is CWE-89 SQL injection in sunnygkp10 Online-Exam-System 2015, specifically the feedback module’s fid parameter. The supplied CVSS 4.0 score is 8.8 with network attack vector, low complexity, no privileges, and no user interaction. Public references include an ExploitDB entry, but the bundle does not show KEV listing or confirmed active exploitation.
Likely exposure
Exposure is limited to organizations running Online-Exam-System 2015, especially public-facing deployments. Risk is higher where the application database contains exam results, credentials, personal data, or administrative records. The source bundle does not identify other affected versions.
Exploitation context
A public ExploitDB reference exists, which increases researcher and attacker awareness. However, no provided source states active exploitation in the wild, and the CVE is not marked KEV in the bundle. The vulnerability appears remotely reachable if the vulnerable feedback module is accessible.
Researcher notes
Evidence is sufficient for affected product, parameter, weakness class, and high severity. Evidence is incomplete on vendor patch availability, active exploitation, and affected versions beyond 2015. Do not assume broader product impact without additional vendor or code confirmation.
Mitigation direction
- Check the vendor repository and advisory sources for any available update or guidance.
- Remove or disable Online-Exam-System 2015 if it is no longer required.
- Restrict access to the feedback module from untrusted networks.
- If maintaining the code, replace dynamic SQL with parameterized queries.
- Apply database least-privilege controls for the application account.
- Use monitoring or WAF rules as temporary compensating controls.
Validation and detection
- Inventory systems for sunnygkp10 Online-Exam-System 2015 deployments.
- Confirm whether the feedback module is enabled and externally reachable.
- Review application code handling the fid parameter for unsafe SQL construction.
- Check web and database logs for suspicious feedback-module requests.
- Validate fixes in a controlled test environment using non-destructive SQL injection checks.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
