Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-9525 is a SQL injection vulnerability found in the itsourcecode Electronic Judging System version 1.0. It specifically affects the /admin/edit_judge.php file where the judge_id parameter is not properly validated. This allows an attacker to inject malicious SQL code remotely without needing to authenticate.
By exploiting this flaw, attackers can manipulate the database queries executed by the system, potentially gaining unauthorized access to data or altering the database.
How can this vulnerability impact me? :
This vulnerability can have serious impacts including unauthorized access to the database, data tampering, leakage of sensitive information, and even gaining control over the system.
Attackers can exploit this vulnerability remotely without any login credentials, using various SQL injection techniques such as boolean-based blind, stacked queries, time-based blind, and UNION queries.
The exploitation may also lead to service disruption and compromise the integrity and availability of the system.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the /admin/edit_judge.php endpoint for SQL injection via the judge_id parameter. Since the exploit does not require authentication, you can attempt to inject SQL payloads to observe abnormal behavior or database errors.
- Use curl or similar tools to send crafted requests to the vulnerable URL, for example: curl "http://targetsite/admin/edit_judge.php?judge_id=1' OR '1'='1"
- Use sqlmap to automate detection and exploitation: sqlmap -u "http://targetsite/admin/edit_judge.php?judge_id=1" --batch
- Monitor network traffic for suspicious requests targeting /admin/edit_judge.php with unusual or malformed judge_id parameters.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include implementing proper input validation and using prepared statements or parameterized queries to prevent SQL injection.
- Sanitize and validate all inputs, especially the judge_id parameter, to ensure only expected values are processed.
- Refactor the code in /admin/edit_judge.php to use prepared statements instead of directly embedding user input in SQL queries.
- Limit database user permissions to the minimum required to reduce the impact of a potential exploit.
- Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The SQL injection vulnerability in the Electronic Judging System allows unauthorized access to the database, which can lead to data tampering, sensitive information leakage, and system control by attackers.
Such unauthorized access and potential data breaches can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data against unauthorized access and breaches.
Failure to remediate this vulnerability could result in violations of these regulations due to compromised confidentiality, integrity, and availability of protected data.
