Operationally, ranked in the top 6.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2023-40057 is a remote code execution flaw in SolarWinds Access Rights Manager, tied to CWE-502 and carrying a CVSS 3.1 score of 9.0. It enables an authenticated user to abuse a SolarWinds service and obtain arbitrary code execution with adjacent network access, low attack complexity, and no user interaction required.
An authenticated attacker positioned on the same network segment can leverage the issue to execute code remotely, resulting in full compromise of confidentiality, integrity, and availability on the affected system due to the changed scope in the CVSS vector.
SolarWinds has published an advisory for CVE-2023-40057 at https://www.solarwinds.com/trust-center/security-advisories/CVE-2023-40057 that addresses the vulnerability and outlines mitigation steps for customers.
The associated EPSS score remains flat at 0.1168 with no material upward trajectory 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.
