Risk Analysis

Adobe ColdFusion is affected by a deserialization of untrusted data vulnerability that can lead to arbitrary code execution. Because this flaw does not require user interaction, it represents a critical risk to the underlying server environment.

There is no known public exploit for this vulnerability, and it is not listed in the KEV catalog. It is remotely exploitable with low attack complexity.

Recommended Action

Apply the latest security updates provided by Adobe for ColdFusion 2021 and 2023 to resolve the deserialization flaw.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-44351 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
