CVE-2022-38108
Published: 20 October 2022
Summary
CVE-2022-38108 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Solarwinds Orion Platform. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 0.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
SolarWinds Platform contains a deserialization of untrusted data vulnerability tracked as CVE-2022-38108 and CWE-502. The flaw affects the SolarWinds Web Console and is reachable by remote attackers who possess Orion admin-level credentials. Successful exploitation permits arbitrary command execution with high impact to confidentiality, integrity, and availability, reflected in the CVSS 3.1 base score of 7.2.
An authenticated remote adversary with Orion administrator privileges can supply malicious serialized data to the affected component and achieve code execution on the underlying server. No unauthenticated or low-privileged attack paths are described.
The EPSS score has reached 0.8863 without an indicated rise from a lower baseline. Public references include SolarWinds and Zero Day Initiative advisories along with proof-of-concept material on Packet Storm, but no further exploitation or patch details are supplied in the source data.

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.
