CVE-2026-11583: SQL Injection in CodeAstro Student Attendance Management System 1.0

Technical summary

CVE-2026-11583 is a SQL injection flaw in /attendance-php/Admin/createClass.php affecting CodeAstro Student Attendance Management System 1.0. The className parameter is not properly sanitized before being incorporated into database queries, enabling an authenticated attacker to execute arbitrary SQL. The CVSS v3.1 score of 6.3 (Medium) reflects the requirement for prior authentication (PR:L), though network-accessible exploitation is possible. CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection) classify the root cause as inadequate input validation and query parameterization.

Business impact

Educational institutions using this system face potential exposure of sensitive student records, instructor data, and attendance information. Compromised databases could enable unauthorized enrollment manipulation, grade tampering, or data exfiltration. Depending on deployment scope, the vulnerability could affect institutional reputation, trigger privacy incident reporting obligations (FERPA, GDPR), and disrupt critical academic operations if database integrity is compromised.

Affected systems

CodeAstro Student Attendance Management System version 1.0 is confirmed vulnerable. Users should verify whether their installations are running this version. The vulnerability resides specifically in the administrative class creation interface, meaning accounts with administrative or class management privileges are the attack vector. Verify your exact product version against vendor documentation before assuming risk.

Exploitability

Public disclosure has occurred, increasing practical exploitation risk. The attack requires valid system credentials, which limits the immediate threat to insider threats or compromised accounts. However, the straightforward nature of SQL injection techniques and the authenticated access requirement (common in educational settings with multiple administrative accounts) suggests moderate real-world exploitability. No evidence indicates active exploitation in the wild at present, but the public nature of the disclosure warrants timely remediation.

Remediation

Contact CodeAstro directly to obtain patched versions of Student Attendance Management System. Until a patch is available, restrict administrative access to the class creation function to trusted personnel only, and implement database-level access controls to limit the damage a compromised account could cause. Consider isolating the system from untrusted networks if feasible. Ensure database backups are current and regularly tested for restore capability.

Patch guidance

Obtain the latest version of CodeAstro Student Attendance Management System directly from the vendor's official website or support portal. Verify the patch version against the vendor's advisory documentation and test in a non-production environment before deployment. The vendor should provide specific version numbers and release notes confirming SQL injection remediation. Prioritize patching of systems accessible to multiple administrative users.

Detection guidance

Monitor database query logs for anomalous SQL syntax, nested queries, or UNION-based injection patterns in the className parameter of class creation requests. Web application firewalls (WAF) should be configured to detect and block common SQL injection payloads. Audit administrative account login activity and filter for unusual class creation requests originating from unexpected users or IP addresses. Query database transaction logs for unexpected data access or modification patterns coinciding with the timing of suspicious administrative sessions.

Why prioritize this

Although CVSS severity is Medium, the vulnerability should be prioritized due to public exploit disclosure, the sensitive nature of educational data at risk, and the relatively low barrier to exploitation for users with administrative credentials. Organizations with distributed administrative teams or legacy credential management practices face elevated risk and should patch urgently.

Risk score, explained

The CVSS v3.1 score of 6.3 reflects limited scope (S:U—no impact beyond the vulnerable system), low confidentiality/integrity/availability impact (C:L/I:L/A:L—partial rather than complete compromise), and importantly, the requirement for prior authentication (PR:L). However, this score does not account for the public disclosure status or the sensitivity of data typically stored in student management systems, both of which should inform organizational risk appetite and remediation priority.
