CVE-2023-26750 : What You Need to Know

This article provides an overview of CVE-2023-26750, a SQL injection vulnerability found in Yii Framework Yii 2 Framework before version 2.0.47. The vulnerability allows a remote attacker to execute arbitrary code via the runAction function. It is important to note that the software maintainer's position is that the vulnerability lies in third-party code, not in the framework itself.

Understanding CVE-2023-26750

CVE-2023-26750 is an SQL injection vulnerability affecting the Yii Framework Yii 2 Framework before version 2.0.47. The issue allows a remote attacker to execute arbitrary code by exploiting the runAction function. Despite being in third-party code, this vulnerability can still pose a significant threat if left unaddressed.

What is CVE-2023-26750?

The CVE-2023-26750 vulnerability is classified as a SQL injection vulnerability within the Yii Framework Yii 2 Framework. This type of vulnerability can be exploited by attackers to manipulate database queries through malicious input, potentially leading to unauthorized access or modification of data.

The Impact of CVE-2023-26750

The impact of CVE-2023-26750 could be severe, as it allows a remote attacker to execute arbitrary code on the targeted system. This could result in data breaches, unauthorized access to sensitive information, and even complete system compromise if not mitigated promptly.

Technical Details of CVE-2023-26750

The technical details of CVE-2023-26750 shed light on the vulnerability's nature, affected systems, and the mechanism through which it can be exploited.

Vulnerability Description

The SQL injection vulnerability in Yii Framework Yii 2 Framework before version 2.0.47 enables attackers to inject and execute malicious SQL queries, bypassing security measures and potentially gaining unauthorized access to the underlying database. This can lead to data exfiltration, data manipulation, and other malicious activities.

Affected Systems and Versions

The vulnerability impacts Yii Framework Yii 2 Framework versions before 2.0.47. Users running these versions are at risk of exploitation if proper security measures are not implemented to address the issue promptly.

Exploitation Mechanism

Attackers can exploit CVE-2023-26750 by crafting malicious input that, when processed by the runAction function, triggers the SQL injection flaw. By injecting specially crafted SQL statements, attackers can manipulate database queries and potentially execute arbitrary code on the targeted system.

Mitigation and Prevention

Mitigating CVE-2023-26750 requires immediate action to secure systems and prevent potential exploitation. Here are some steps to consider for mitigation and prevention:

Immediate Steps to Take

Update to Yii Framework Yii 2 Framework version 2.0.47 or newer to patch the vulnerability.
Implement input validation and parameterized queries to prevent SQL injection attacks.
Regularly monitor and audit database activities to detect any unauthorized access or suspicious queries.

Long-Term Security Practices

Follow secure coding practices to mitigate the risk of SQL injection vulnerabilities in your applications.
Conduct regular security assessments and penetration testing to identify and address potential security weaknesses.
Educate developers and users about the importance of secure coding practices and the risks associated with SQL injection vulnerabilities.

Patching and Updates

Stay updated on security advisories and patches released by Yii Framework Yii 2 Framework to address known vulnerabilities promptly. Timely patching and updates can help prevent exploitation and enhance the overall security posture of your systems.
