Summary

CVE-2025-29310 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Opennetworking Onos. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Mandates validation of untrusted LLDP packet inputs to directly prevent deserialization of malicious payloads leading to arbitrary command execution.

SI-2 Flaw Remediation good match

prevent

Requires timely identification and remediation of the specific deserialization flaw in ONOS v2.7.0 through patching or upgrades.

SC-7 Boundary Protection partial match

prevent

Enforces network boundaries to filter or block crafted LLDP packets before they reach the vulnerable deserialization component.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1059 Command and Scripting Interpreter Execution

Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Why these techniques?

The deserialization flaw in ONOS enables remote exploitation of a network-accessible application (T1190) via malicious LLDP packets, directly resulting in arbitrary command execution (T1059).

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

An issue in onos v2.7.0 allows attackers to trigger a packet deserialization problem when supplying a crafted LLDP packet. This vulnerability allows attackers to execute arbitrary commands or access network information.

Deeper analysisAI

CVE-2025-29310 is a critical deserialization vulnerability (CWE-502) affecting ONOS version 2.7.0, published on 2025-03-24. The flaw arises from inadequate handling of crafted Link Layer Discovery Protocol (LLDP) packets, enabling a packet deserialization issue that compromises the software's integrity.

Remote attackers require no privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8) and can exploit it by supplying a malicious LLDP packet over the network. Successful exploitation allows arbitrary command execution or unauthorized access to network information.
