Lifecycle Timeline
1DescriptionNVD
Project files are stored memory objects in the form of binary serialized data that can later be read and deserialized again to instantiate the original objects in memory. Malicious manipulation of these files may allow an attacker to corrupt memory.
AnalysisAI
Project files are stored memory objects in the form of binary serialized data that can later be read and deserialized again to instantiate the original objects in memory. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. 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. Project files are stored memory objects in the form of binary serialized data that can later be read and deserialized again to instantiate the original objects in memory. Malicious manipulation of these files may allow an attacker to corrupt memory. Affected products include: Azeotech Daqfactory.
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.
