CVE-2024-3054
Published: 12 April 2024
Summary
CVE-2024-3054 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Wpvivid Migration\, Backup\, Staging. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 4.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The WPvivid Backup & Migration plugin for WordPress is affected by a PHAR deserialization vulnerability in all versions through 0.9.99. The flaw exists in the wpvividstg_get_custom_exclude_path_free action handler, which accepts untrusted input via the tree_node[node][id] parameter without adequate path validation, allowing a PHAR wrapper to trigger object deserialization (CWE-502). The issue carries a CVSS 3.1 score of 7.2.
An authenticated attacker with administrative privileges can supply a malicious PHAR reference to invoke arbitrary PHP objects. Although the plugin itself contains no POP chain, the presence of a suitable chain from another installed plugin or theme could enable deletion of arbitrary files, disclosure of sensitive data, or remote code execution.
Public references point to a patched changeset on the WordPress plugin repository and a detailed advisory from Wordfence that identify the affected code path and confirm the availability of an updated version. The EPSS score has remained at 0.2050 with no indicated post-disclosure increase.

Vulnerability details
WPvivid Backup & Migration Plugin for WordPress is vulnerable to PHAR Deserialization in all versions up to, and including, 0.9.99 via deserialization of untrusted input at the wpvividstg_get_custom_exclude_path_free action. This is due to the plugin not providing sufficient path validation…
more
on the tree_node[node][id] parameter. This makes it possible for authenticated attackers, with admin-level access and above, to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

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.
