Summary

CVE-2024-8255 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Deltaww Dtn Soft. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 45% 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.

Delta Electronics DTN Soft versions 2.0.1 and earlier contain a deserialization of untrusted data flaw (CWE-502) that permits remote code execution. The affected component is the DTN Soft industrial software package, which carries a CVSS 4.0 score of 8.4 reflecting local attack vector, low complexity, no privileges required, and active user interaction.

An unauthenticated attacker can supply a crafted serialized object that the application deserializes, resulting in arbitrary code execution on the victim system with high impact to confidentiality, integrity, and availability. Successful exploitation therefore requires the victim to process attacker-controlled input locally, after which the attacker gains full control of the process and potentially the host.

CISA has published ICSA-24-242-02 to document the issue and coordinate vendor guidance for affected users. The EPSS score has remained flat at 0.0559 with no material increase since disclosure.

Mitigating Controls

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 none match
prevents

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cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

finds

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.

prevents

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
