Operationally, ranked in the top 20.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

A deserialization of untrusted data vulnerability exists in the download file function of Soar Cloud HRD Human Resource Management System through version 7.3.2025.0408. The flaw, tracked as CVE-2025-48780 and assigned CWE-502, permits remote attackers to supply a crafted serialized object that results in arbitrary system command execution. It carries a CVSS 4.0 score of 9.9, reflecting network attack vector, low complexity, and no required privileges or user interaction.

Remote unauthenticated attackers can exploit the issue over the network by sending a malicious serialized payload to the affected download file endpoint, achieving full system command execution on the target server. The EPSS score remains flat at 0.0126 with no material increase since disclosure.

An advisory describing the vulnerability is available at https://zuso.ai/advisory/za-2025-05.

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-502

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

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-502

Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.

addresses: CWE-502

Integrity verification of serialized information can detect tampering before deserialization occurs.

addresses: CWE-502

Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
