Vulnerability Details
According to the official CVE description, Froxlor through version 0.10.29.1 allows SQL injection in Database/Manager/DbManagerMySQL.php via a custom DB name. The vulnerability has a CVSS score of 9.8, indicating a critical severity level. This high severity emphasizes the potential risks associated with SQL injection attacks, including unauthorized access to sensitive data and manipulation of database contents.
The vulnerability is classified under CWE-89, which specifically addresses SQL injection issues. The attack vector is categorized as network-based, and the attack complexity is considered low, meaning that an attacker does not require extensive skills to exploit this vulnerability.
Froxlor is a widely used open-source server management software, which increases the blast radius of this vulnerability significantly. Organizations utilizing this software should be particularly vigilant.
Technical Analysis
The root cause of CVE-2021-42325 is the failure to properly sanitize user input when constructing database queries. As a result, an attacker can inject malicious SQL commands through the custom database name field, allowing unauthorized access and manipulation of the database.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without local access. The attack complexity is low, requiring no special privileges or user interaction. The impact on confidentiality, integrity, and availability is high, as attackers can potentially access sensitive data, alter database records, or even disrupt service.
Risk & Impact Analysis
Organizations utilizing Froxlor must recognize the significant risk posed by CVE-2021-42325. The ability for attackers to exploit this vulnerability remotely increases the likelihood of data breaches. Given the critical nature of the CVSS score, organizations should implement immediate remediation efforts to prevent potential data exposure and loss.
The vulnerabilities in widely adopted software like Froxlor can have a broad impact, affecting numerous organizations. The potential for unauthorized access to sensitive information necessitates that organizations prioritize this vulnerability in their patch management cycles.
The urgency of addressing this vulnerability is further underscored by its exploitability status, as known exploits and public proof of concept code are available, making it a target for attackers.
