With well-known organizations like British Airways, Boots, the BBC, and several of Zellis’ customers falling victim to its effects, the consequences of this vulnerability are far-reaching.
The MOVEit Transfer vulnerability affects the Progress MOVEit Transfer software and is assigned the Common Vulnerabilities and Exposures (CVE) number CVE-2023-34362. In response to this vulnerability, Progress Software issued a security advisory on May 31st, 2023, which included indicators of compromise (IOCs).
FortiGuard Labs, a leading cybersecurity research organisation, strongly recommends that MOVEit Transfer users apply all patches and implement mitigations provided by the vendor without delay.
The Nature of SQL Injection Attacks
An SQL injection attack is a type of cyber attack that exploits malicious SQL code to manipulate backend databases and gain access to information not intended to be displayed.
By exploiting vulnerabilities in web applications that enable malicious actors to inject malicious SQL code into the application or database engine, attackers can manipulate the database and access data that was not intended to be exposed.
This unauthorised access could include stealing sensitive data, modifying, deleting, or extracting data from a database.
To safeguard against SQL injection attacks, organizations should implement secure coding practices, input validation, and parameterized queries. Additionally, they should regularly review logs and update service account credentials to ensure data security.
Staying vigilant and prepared is crucial in the fight against these types of attacks, as they pose a significant threat to an organization’s most valuable asset: its data.
Affected MOVEit Transfer Versions
All MOVEit Transfer versions prior to 2021.0.6, 2021.1.4, 2022.0.4, 2022.1.5, and 2023.0.1 are impacted by the CVE-2023-34362 vulnerability, making these versions susceptible to SQL injection attacks.
Attackers exploiting this vulnerability can potentially result in data exfiltration and web shell backdoor deployment, among other malicious activities.
It is of utmost importance that organizations using affected MOVEit Transfer versions update to a supported version and follow the recommended security practices.
By doing so, organizations can greatly reduce the risk of falling victim to this critical vulnerability and protect their valuable data from unauthorized access and manipulation.
Attackers’ Exploitation Techniques
The Cl0p ransomware threat actor has exploited the MOVEit Transfer vulnerability by utilizing web shell backdoors and data exfiltration techniques to wreak havoc on multiple organizations.
As a result, understanding these exploitation techniques is key to mitigating the risks posed by the CVE-2023-34362 vulnerability and safeguarding both the affected organizations and their supply chains.
In order to effectively combat these threats, we must first dive deep into the different techniques employed by attackers, including web shell backdoor deployment and data exfiltration tactics.
By understanding these tactics, we can better prepare ourselves and our organizations for potential attacks and implement the necessary security measures to keep our data safe.
Web Shell Backdoor Deployment
Web shell backdoors are malicious scripts installed on vulnerable systems after exploiting the CVE-2023-34362 vulnerability, and are used to execute commands through HTTP request headers.
Attackers gain access to systems by deploying a web shell in the wwwroot folder of the MOVEit install directory, providing them with remote access and control over the compromised web server.
By understanding how web shell backdoors are deployed and how they function, organizations can better protect themselves against this form of attack.
This knowledge can be used to identify potential vulnerabilities and implement the necessary security measures to prevent unauthorized access to sensitive data and systems.
Data Exfiltration Tactics
Data exfiltration refers to the unauthorized transfer or movement of data from a device or network, often involving the theft or unauthorized removal of data by a cybercriminal through various cyberattack methods.
In the context of the MOVEit Transfer vulnerability, attackers may employ data exfiltration tactics such as deleting service accounts, delete database elements, listing database files, and creating new service accounts.
Understanding these data exfiltration tactics is crucial in mitigating the risks associated with the CVE-2023-34362 vulnerability.
By recognising the methods employed by attackers to exfiltrate data, organizations can identify potential threats and implement the necessary security measures to protect their sensitive information from unauthorised access and theft.
Mitigating the MOVEit Transfer Vulnerability
To mitigate the risks associated with the MOVEit Transfer vulnerability, FortiGuard Labs recommends a series of measures for MOVEit Transfer users, such as disabling HTTP and HTTPS traffic, reviewing Azure logs, applying patches, and enabling HTTP and HTTPS traffic once patches have been applied.
By following these recommendations, organizations can significantly reduce their exposure to the CVE-2023-34362 vulnerability and protect their data from potential attacks.
In addition to these measures, monitoring for indicators of compromise is essential in detecting potential threats and ensuring the security of your organisation. In the following sections, we’ll discuss these mitigation measures in more detail and provide guidance on how to implement them effectively.
Applying Security Patches
Applying security patches is a critical step in addressing the MOVEit Transfer vulnerability and protecting your organization from potential attacks.
The process of applying security patches depends on the supported version of MOVEit Transfer being used. Once the appropriate patch has been applied, it is important to verify its installation and monitor the system for any changes or potential issues.
In addition to applying security patches, regularly reviewing logs and updating service account credentials can help ensure the security of your files created in MOVEit Transfer environment.
By diligently monitoring your system and implementing these best practices, you can significantly reduce the risk of falling victim to the CVE-2023-34362 vulnerability and maintain the integrity of your data.
Disabling and Enabling Web Traffic
Another key measure recommended by FortiGuard Labs to mitigate the MOVEit Transfer vulnerability is to disable HTTP and HTTPS traffic on ports 80 and 443.
This can be done by accessing the MOVEit Transfer server and disabling the protocols in the configuration settings. Once the appropriate security patches have been applied, HTTP and HTTPS traffic can be re-enabled to restore normal functionality.
In addition to disabling and enabling web traffic, reviewing Azure logs is an important step in identifying potential indicators of compromise and ensuring the security of your MOVEit Transfer environment.
By implementing these mitigation measures and regularly monitoring your system, you can effectively reduce the risk of falling victim to the CVE-2023-34362 vulnerability.
Monitoring for Indicators of Compromise
Monitoring for indicators of compromise (IOCs) is an essential part of any comprehensive security strategy.
In the context of the MOVEit Transfer vulnerability, FortiGuard Labs has released AV and IPS signatures to protect against web shell backdoors and CVE-2023-34362. For further information on these signatures and additional mitigation measures, users can refer to the Outbreak Alert page provided by FortiGuard Labs.
