Deeper analysis
SolarWinds Platform is affected by a deserialization of untrusted data vulnerability tracked as CVE-2022-36958. The flaw resides in the SolarWinds Web Console and carries a CVSS 3.1 score of 8.8, corresponding to CWE-502. It enables remote code execution when untrusted data is deserialized without sufficient validation.
A remote attacker who already possesses valid credentials for the SolarWinds Web Console can supply a malicious serialized object and achieve arbitrary command execution on the underlying system. The attack requires no user interaction and can be performed over the network with low complexity.
Public advisories published by SolarWinds and Zero Day Initiative at the referenced URLs describe the issue and direct administrators to available patches and configuration guidance for the affected platform versions.
The associated EPSS score reached a peak of 0.1698 and currently stands at 0.1480, indicating moderate and relatively stable exploitation interest since 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.
