CVE-2025-2244
Published: 04 April 2025
Summary
CVE-2025-2244 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Bitdefender Gravityzone. Its CVSS base score is 9.5 (Critical).
Operationally, ranked in the top 24.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A vulnerability exists in the sendMailFromRemoteSource method within Emails.php of the Bitdefender GravityZone Console. The method passes untrusted user input directly to PHP's unserialize() function without validation, enabling PHP object injection that can be chained to arbitrary file writes and command execution on the underlying host. The flaw is tracked as CVE-2025-2244 with a CVSS 4.0 score of 9.5 and is classified under CWE-502.
An unauthenticated remote attacker can supply a crafted serialized payload to the affected endpoint, triggering object injection that leads to full control of the GravityZone Console host. No user interaction or special privileges are required, and the attack can be performed over the network with low complexity.
The vendor advisory at http://bitdefender.com/support/security-advisories/insecure-php-deserialization-issue-in-gravityzone-console-va-12634 addresses the issue and is the authoritative source for mitigation steps. The associated EPSS score rose from a low baseline to a recorded peak of 0.0186, indicating emerging exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
