DescriptionNVD

The affected product lacks proper validation of user-supplied data, which can result in deserialization of untrusted data on the Ignition 8 Gateway (versions prior to 8.0.10) and Ignition 7 Gateway (versions prior to 7.9.14), allowing an attacker to obtain sensitive information.

AnalysisAI

The affected product lacks proper validation of user-supplied data, which can result in deserialization of untrusted data on the Ignition 8 Gateway (versions prior to 8.0.10) and Ignition 7 Gateway. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Technical ContextAI

This vulnerability is classified as Deserialization of Untrusted Data (CWE-502), which allows attackers to execute arbitrary code through malicious serialized objects. The affected product lacks proper validation of user-supplied data, which can result in deserialization of untrusted data on the Ignition 8 Gateway (versions prior to 8.0.10) and Ignition 7 Gateway (versions prior to 7.9.14), allowing an attacker to obtain sensitive information. Affected products include: Inductiveautomation Ignition Gateway. Version information: prior to 8.0.10.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid deserializing untrusted data. Use safe serialization formats (JSON). Implement integrity checks and type allowlists.
