Summary

CVE-2025-49219 is a critical-severity Use of Obsolete Function (CWE-477) vulnerability in Trendmicro Apex Central. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 7.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

An insecure deserialization vulnerability exists in Trend Micro Apex Central versions below 8.0.7007. The issue stems from an operation matching CWE-502 and CWE-477 that permits unauthenticated remote code execution on affected installations; the flaw is distinct from the similar CVE-2025-49220 but resides in a separate code path.

An attacker with network access can exploit the weakness without authentication or user interaction, resulting in full compromise of confidentiality, integrity, and availability as reflected in the CVSS 9.8 rating.

Public advisories and patches addressing the issue are available from Trend Micro and the Zero Day Initiative at the listed reference URLs. The associated EPSS score has remained modest, with a current value of 0.0776 and a recorded peak of 0.0921.

Mitigating Controls

Likely Mitigating Controls AI

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.

addresses: CWE-502

Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.

addresses: CWE-477

Institutionalized information sharing keeps developers aware of obsolete functions and the need to replace them with supported alternatives.

addresses: CWE-477

Regular reassessment flags use of obsolete functions whose security properties have degraded or whose replacements contain fixes for known weaknesses.

addresses: CWE-502

Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.

addresses: CWE-477

Eliminates reliance on functions or components explicitly declared obsolete and unsupported by their maintainers.

addresses: CWE-502

Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.

addresses: CWE-502

Validates or rejects untrusted serialized data before deserialization occurs.

addresses: CWE-477

Software and firmware updates replace obsolete functions whose retained presence leaves systems exposed to publicly known weaknesses.
