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-2024-22320 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Ibm Operational Decision Manager. 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 0.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
IBM Operational Decision Manager 8.10.3 contains an unsafe deserialization flaw tracked as CVE-2024-22320 and CWE-502. The vulnerability resides in the handling of serialized objects and enables remote code execution when untrusted input is processed.
A remote authenticated attacker can exploit the issue by submitting a specially crafted request, resulting in arbitrary code execution under the SYSTEM context. The flaw is rated 9.8 on CVSS 3.1 with an attack vector of network, no required privileges or user interaction, and full impact on confidentiality, integrity, and availability.
IBM has published remediation guidance at its support pages referenced under X-Force ID 279146. The associated EPSS score currently stands at 0.9084 with a recorded peak of 0.9233, and public technical write-ups detail the Java deserialization path used to reach code execution.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
