CVE-2012-3951 in SonicWALL Scrutinizer
Summary
by MITRE
The MySQL component in Plixer Scrutinizer (aka Dell SonicWALL Scrutinizer) 9.0.1.19899 and earlier has a default password of admin for the (1) scrutinizer and (2) scrutremote accounts, which allows remote attackers to execute arbitrary SQL commands via a TCP session.

The vulnerability identified as CVE-2012-3951 affects the MySQL database component within Plixer Scrutinizer, formerly known as Dell SonicWALL Scrutinizer, version 9.0.1.19899 and earlier. This represents a critical security flaw that stems from the improper configuration of database access credentials, specifically the presence of default passwords for administrative accounts. The affected system contains two primary accounts with the same default password of "admin" - the scrutinizer account and the scrutremote account. These accounts are configured with minimal privilege levels but possess sufficient access to interact with the underlying MySQL database system, creating a significant attack surface for malicious actors.
The technical exploitation of this vulnerability occurs through a TCP session connection to the MySQL service, which allows remote attackers to establish communication with the database server. Once connected, attackers can leverage the default administrative credentials to authenticate successfully and subsequently execute arbitrary SQL commands against the database. This capability enables attackers to perform a wide range of malicious activities including data extraction, modification, or deletion, as well as potential privilege escalation within the database environment. The vulnerability is particularly dangerous because it requires no advanced exploitation techniques beyond establishing a network connection and using the well-known default password, making it accessible to attackers with minimal technical expertise.
The operational impact of this vulnerability extends beyond simple unauthorized database access, as it can lead to complete system compromise and data breaches. Attackers can manipulate network traffic data that Scrutinizer is designed to monitor and analyze, potentially corrupting or destroying critical network intelligence information. The default password configuration represents a fundamental security misconfiguration that violates the principle of least privilege, as administrative accounts should never be configured with easily guessable credentials. This vulnerability also demonstrates poor security hygiene in the software deployment process, where default configurations are not properly changed during installation, leaving systems exposed to automated attacks that target known default credentials.
The vulnerability maps directly to CWE-798, which identifies the use of hard-coded credentials, and CWE-312, which addresses the exposure of sensitive information through cleartext storage or transmission. From an ATT&CK framework perspective, this vulnerability corresponds to T1190 - Exploit Public-Facing Application, T1078 - Valid Accounts, and T1046 - Network Service Scanning, as attackers can leverage the default credentials to establish persistent access and move laterally within the network. Organizations using affected versions of Scrutinizer face significant risk of unauthorized access to network monitoring data, which could compromise security operations and potentially expose sensitive network intelligence. The vulnerability also highlights the importance of proper security configuration management and the need for regular security assessments to identify and remediate default credential issues.
Mitigation strategies should include immediate password changes for all administrative accounts, implementation of strong authentication mechanisms, and regular security configuration reviews. Organizations should disable unnecessary services and accounts, implement network segmentation to limit access to database systems, and conduct regular vulnerability assessments to identify similar misconfigurations. The affected software versions should be updated to patched releases that address the default credential issue and implement proper authentication controls. Additionally, security monitoring should be enhanced to detect unauthorized access attempts and credential compromise events, while access controls should be implemented to restrict database access to authorized personnel only. Regular security training for administrators should emphasize the importance of changing default passwords and maintaining proper security configurations throughout the system lifecycle.
