CVE-2025-2244 in GravityZone Console
Summary
by MITRE • 04/04/2025
A vulnerability in the sendMailFromRemoteSource method in Emails.php as used in Bitdefender GravityZone Console unsafely uses php unserialize() on user-supplied input without validation. By crafting a malicious serialized payload, an attacker can trigger PHP object injection, perform a file write, and gain arbitrary command execution on the host system.

The vulnerability identified as CVE-2025-2244 resides within the Bitdefender GravityZone Console application where the sendMailFromRemoteSource method in Emails.php fails to properly validate user-supplied input before processing it through php unserialize(). This represents a critical security flaw that directly maps to CWE-502, which describes the unsafe use of the unserialize function in php applications. The vulnerability exists because the application accepts serialized data from remote sources without implementing proper input sanitization or validation mechanisms, creating an avenue for malicious actors to exploit the system through object injection attacks.
The technical implementation of this vulnerability allows attackers to craft malicious serialized payloads that, when processed by the unserialize() function, trigger PHP object injection. This injection occurs because the application does not validate the serialized data against a whitelist of allowed classes or perform proper input sanitization before deserialization. The flaw enables attackers to manipulate the object graph during the unserialization process, potentially leading to arbitrary code execution on the host system. This type of vulnerability is particularly dangerous because it can be leveraged to execute system commands, modify application behavior, and gain persistent access to the affected environment.
The operational impact of CVE-2025-2244 is severe and multifaceted, as it provides attackers with a pathway to achieve arbitrary command execution on the system hosting the Bitdefender GravityZone Console. This capability allows threat actors to perform actions such as installing backdoors, exfiltrating sensitive data, modifying system configurations, or escalating privileges within the network. The vulnerability can be exploited remotely, making it particularly attractive to attackers who seek to compromise enterprise security infrastructure. Organizations using Bitdefender GravityZone Console are at risk of complete system compromise, especially if the application runs with elevated privileges or has access to sensitive network resources.
Mitigation strategies for this vulnerability should include immediate patching of the affected Bitdefender GravityZone Console version, as well as implementing input validation and sanitization measures to prevent unauthorized deserialization of user-supplied data. Organizations should also consider implementing network segmentation and monitoring to detect suspicious activities related to email processing or file write operations. According to ATT&CK framework, this vulnerability maps to T1059.007 for remote code execution and T1190 for exploitation of remote services, making it a critical target for defensive measures. Additional protective measures include disabling unnecessary remote email functionality, implementing web application firewalls, and conducting regular security assessments to identify similar vulnerabilities in other applications that may use similar deserialization patterns.
