CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2017-3066 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Adobe Coldfusion. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Adobe ColdFusion 2016 Update 3 and earlier, ColdFusion 11 Update 11 and earlier, and ColdFusion 10 Update 22 and earlier contain a Java deserialization vulnerability (CWE-502) in the Apache BlazeDS library. The flaw carries a CVSS 3.1 score of 9.8 and permits unauthenticated remote code execution when untrusted data is deserialized.
An attacker with network access can supply a crafted serialized Java object to the affected BlazeDS endpoint without authentication or user interaction. Successful exploitation grants arbitrary code execution with the privileges of the ColdFusion process, resulting in full confidentiality, integrity, and availability impact on the server.
The Adobe security bulletin APSB17-14 at https://helpx.adobe.com/security/products/coldfusion/apsb17-14.html addresses the issue and provides patch information for supported ColdFusion releases. Public exploit code for the vulnerability has been published on Exploit-DB.

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.
