CVE-2021-44427 is a critical unauthenticated SQL Injection vulnerability in the Rosario Student Information System (rosariosis) prior to version 8.1.1. This vulnerability allows remote attackers to execute arbitrary PostgreSQL statements through the /Side.php script via the syear parameter. The severity of this vulnerability is underscored by its CVSS score of 9.8, indicating a critical risk level.
The ability to execute SQL commands such as SELECT, INSERT, UPDATE, and DELETE poses significant security risks. Organizations using affected versions of rosariosis should be particularly vigilant, as the vulnerability can lead to unauthorized access to sensitive data and system compromise.
Currently, there is no known exploit for this vulnerability, but the potential for exploitation exists. Organizations are urged to prioritize patching this vulnerability immediately to prevent possible attacks.
Failure to address this vulnerability could result in significant damage, highlighting the urgency for defenders to take action.
Vulnerability Details
The official CVE description states that an unauthenticated SQL Injection vulnerability in the Rosario Student Information System (rosariosis) before 8.1.1 allows remote attackers to execute PostgreSQL statements through /Side.php via the syear parameter. The vulnerability type is classified under CWE-89, which pertains to SQL Injection.
With a CVSS score of 9.8, this vulnerability is classified as critical. The high score is attributed to the potential confidentiality, integrity, and availability impacts, each rated as high. The vulnerability was published on November 29, 2021, and has been modified since.
Technical Analysis
The root cause of CVE-2021-44427 lies in the lack of input validation for the syear parameter used by the /Side.php script. Attackers can manipulate this parameter to inject arbitrary SQL commands, exploiting the application's failure to sanitize user inputs.
The attack vector for this vulnerability is network-based, requiring no privileges or user interaction. The attack complexity is low, making it easy for potential attackers to exploit this vulnerability remotely.
Exploiting this vulnerability can lead to high impacts on confidentiality, integrity, and availability, as attackers gain unauthorized access to the database and can modify or delete data.
Risk & Impact Analysis
Risk to organizations includes unauthorized data access, potential data loss, and system manipulation. The critical nature of the vulnerability necessitates immediate attention from security teams to mitigate risks. Organizations must assess their exposure to this vulnerability and implement necessary patches without delay.
The potential blast radius is extensive, given the widespread use of the rosariosis platform. Organizations leveraging this system should evaluate their configurations and ensure they are not susceptible to SQL Injection attacks.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of rosariosis prior to 8.1.1 are affected by this vulnerability. Organizations are encouraged to verify their current version and apply necessary updates.
Mitigation & Remediation
Organizations should prioritize patching the rosariosis system to version 8.1.1 or later to eliminate this vulnerability. If immediate patching is not possible, it is crucial to implement stringent input validation and sanitize user inputs to mitigate the risk of SQL Injection attacks. Additionally, consider conducting a thorough security assessment to identify and remediate other potential vulnerabilities.
