CVE-2024-12727 is a critical pre-auth SQL injection vulnerability in the email protection feature of Sophos Firewall versions older than 21.0 MR1 (21.0.1). This vulnerability allows attackers to access the reporting database, which can lead to remote code execution if a specific configuration of Secure PDF eXchange (SPX) is enabled, particularly when the firewall is running in High Availability (HA) mode. The CVSS score of 9.8 indicates a critical severity level, making this vulnerability a significant threat to organizations using affected versions.
Organizations using Sophos Firewall must address this vulnerability immediately. The potential impact includes unauthorized access to sensitive information and system control, posing a severe risk to the integrity and availability of their systems. Given the low attack complexity and the fact that no privileges or user interaction are required, this vulnerability is particularly dangerous.
As of now, there are no known exploits in the wild, but the critical nature of this vulnerability necessitates prompt action. Organizations should prioritize patching affected systems as part of their immediate remediation efforts.
Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability, classified under CWE-89, is related to SQL injection, which allows attackers to manipulate database queries. The vulnerability affects Sophos Firewall versions prior to 21.0 MR1 (21.0.1), and it was published on December 19, 2024. The CVSS 3.1 vector string indicates a network attack vector, low attack complexity, no privileges required, and no user interaction necessary, resulting in high impacts on confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2024-12727 is improper input validation within the email protection feature of Sophos Firewall. This SQL injection vulnerability can be exploited through crafted requests that manipulate SQL commands executed by the application, enabling attackers to access the reporting database.
The attack vector is network-based, requiring no user interaction, and the attack complexity is low, which means that an attacker could exploit this vulnerability with relative ease. The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation could lead to severe system compromise.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive reporting data, potential data breaches, and the possibility of remote code execution. Given the nature of the vulnerability and its critical CVSS score of 9.8, organizations must take immediate action to patch their systems or implement workarounds to mitigate the risk. The urgency for remediation is high, and failure to address this vulnerability could expose organizations to significant operational risks.
