CVE-2023-44353
Published: 17 November 2023
Summary
CVE-2023-44353 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Adobe Coldfusion. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Adobe ColdFusion versions 2023.5 and earlier as well as 2021.11 and earlier contain a deserialization of untrusted data flaw (CWE-502) that permits arbitrary code execution. The vulnerability carries a CVSS 3.1 score of 9.8 with network attack vector, low complexity, and no required privileges or user interaction.
An unauthenticated attacker can send a crafted serialized object over the network to trigger the flaw and obtain full control of the affected ColdFusion instance, resulting in complete compromise of confidentiality, integrity, and availability.
Adobe has published security bulletin APSB23-52 at helpx.adobe.com/security/products/coldfusion/apsb23-52.html to address the issue.
The associated EPSS score stands at 0.9089, indicating substantial 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.
