The vulnerability identified as CVE-2021-44567 represents a critical security flaw in the RosarioSIS educational management system affecting versions prior to 7.6.1. This issue manifests as an unauthenticated SQL injection vulnerability within the ProgramFunctions/PortalPollsNotes.fnc.php file, specifically targeting the votes parameter. The vulnerability exposes the system to potential exploitation by malicious actors who can manipulate database queries without requiring valid authentication credentials, creating a significant risk for educational institutions relying on this platform for student information management and administrative functions.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the PortalPollsNotes.fnc.php script. When the votes parameter is processed, the application fails to properly escape or filter user-supplied data before incorporating it into SQL query constructs. This allows attackers to inject malicious SQL code that can manipulate the database structure, extract sensitive information, modify records, or potentially gain unauthorized access to the underlying database system. The vulnerability classifies under CWE-89 which specifically addresses SQL injection flaws where untrusted data is directly incorporated into SQL commands without proper sanitization measures.
The operational impact of this vulnerability extends beyond simple data compromise, as it can lead to complete system infiltration and data exfiltration within educational environments. Attackers exploiting this vulnerability could access student records, personal information, academic performance data, and administrative credentials stored within the RosarioSIS database. The unauthenticated nature of this flaw means that even without valid user accounts, threat actors can leverage this vulnerability to perform unauthorized database operations. This poses particular risk to institutions handling sensitive educational data, as the vulnerability could enable large-scale data breaches affecting thousands of students and staff members.
Organizations utilizing RosarioSIS should immediately implement the remediation measures provided in version 7.6.1 which includes proper input validation and parameterized query implementations. Security teams should also consider implementing network-level protections such as web application firewalls to detect and block malicious SQL injection attempts. The vulnerability aligns with ATT&CK technique T1190 which covers exploitation of remote services through SQL injection attacks, emphasizing the need for comprehensive security monitoring and incident response capabilities. Additionally, organizations should conduct thorough security assessments of their educational management systems and implement regular vulnerability scanning to identify similar weaknesses in their technology infrastructure.
