CVE-2023-30204 is a critical SQL injection vulnerability found in the Judging Management System v1.0, specifically through the judge_id parameter in the /php-jms/edit_judge.php endpoint. This vulnerability allows attackers to execute arbitrary SQL queries, potentially leading to unauthorized access to sensitive information, data manipulation, or even complete system compromise.
With a CVSS score of 9.8, this vulnerability is classified as critical. The potential impact on confidentiality, integrity, and availability is significant, as attackers can exploit this flaw remotely with no authentication required.
Risk to organizations includes exposure of sensitive data and disruption of operations, making this an urgent issue to address. Organizations are advised to prioritize patching immediately.
Currently, there are no known exploits or public proof of concept available for this vulnerability, but the absence of these does not mitigate the risk posed by such a severe flaw.
Vulnerability Details
The vulnerability is categorized under CWE-89, which indicates SQL injection vulnerabilities. The flaw was made public on May 3, 2023, and impacts all versions of the Judging Management System prior to the vendor's patch.
The attack vector is classified as NETWORK, and it has low attack complexity with no privileges required for exploitation. Additionally, user interaction is not necessary, which increases the risk of automated attacks.
Organizations must treat this vulnerability with the utmost urgency due to its critical classification, as the potential impact could lead to catastrophic data breaches.
Technical Analysis
The root cause of this vulnerability lies in improper input validation when handling the judge_id parameter. Attackers can inject malicious SQL commands through this parameter, allowing them to manipulate the underlying database.
Given the low complexity of the attack, an attacker can exploit this vulnerability without needing any special knowledge or extensive resources. The required privileges are none, and there is no need for user interaction, making it easier for attackers to carry out their malicious activities.
The impact on confidentiality, integrity, and availability is high. Unauthorized access to sensitive data may lead to severe consequences for affected organizations, including reputational damage and financial losses.
Risk & Impact Analysis
Organizations deploying the Judging Management System are at significant risk due to this vulnerability. The potential for unauthorized data access could lead to compliance violations and legal ramifications, especially for organizations that handle sensitive information.
The blast radius of this vulnerability is extensive, as attackers may gain access to all data managed by the system. This could include personally identifiable information, competition results, and administrative data.
Given the CVSS score and the lack of known exploits, organizations should assess their risk posture and prioritize remediation efforts during their patch cycles.
Exploitation Status
