CVE-2023-29919 is a critical vulnerability affecting Contec's SolarView Compact firmware version 6.0 and earlier. This vulnerability allows unauthorized access to any file on the server due to insecure permissions associated with the texteditor.php file. The implications of this vulnerability are severe, as it may allow attackers to read or modify sensitive files without proper authorization.
The CVSS score for this vulnerability is 9.1, categorizing it as critical. This high severity rating indicates significant risk to organizations using this firmware. Attackers can exploit this vulnerability over the network with low complexity and no privileges required, making it highly accessible for exploitation.
Organizations utilizing Contec's SolarView Compact should prioritize addressing this vulnerability immediately. The potential for unauthorized access to sensitive information poses a serious risk to confidentiality and integrity.
As of the latest information, there is a public proof of concept available on GitHub related to this vulnerability, underscoring the urgency for organizations to remediate this issue.
Vulnerability Details
The official description of this vulnerability states that 'SolarView Compact <= 6.0 is vulnerable to Insecure Permissions. Any file on the server can be read or modified because texteditor.php is not restricted.' The CWE classification for this vulnerability is CWE-276, which refers to improper authorization.
The vulnerability has a CVSS score of 9.1, indicating a critical severity level. The attack vector is network-based, requiring no privileges and no user interaction. The confidentiality and integrity impacts are both rated as high, while the availability impact is none. This makes the vulnerability particularly dangerous, as it can be exploited remotely without any special access.
Technical Analysis
The root cause of this vulnerability lies in the insecure permissions set on the texteditor.php file, which leads to unauthorized file access. The attack vector allows attackers to exploit this vulnerability over a network with low complexity. No privileges are required to exploit this vulnerability, and user interaction is not needed. The high confidentiality and integrity impact underscores the importance of addressing this vulnerability promptly.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive files, potentially leading to data breaches, operational disruptions, and reputational damage. The blast radius for this vulnerability is significant, as it affects any server running the vulnerable version of SolarView Compact firmware. Organizations should assess their deployment of this software and prioritize remediation based on the criticality of the data involved.
Given the critical CVSS score and the availability of a public proof of concept, organizations must act swiftly. The urgency for remediation is critical to prevent potential exploitation.
