DescriptionNVD

Manuskript through 0.12.0 allows remote attackers to execute arbitrary code via a crafted settings.pickle file in a project file, because there is insecure deserialization via the pickle.load() function in settings.py. NOTE: the vendor's position is that the product is not intended for opening an untrusted project file

AnalysisAI

Manuskript through 0.12.0 allows remote attackers to execute arbitrary code via a crafted settings.pickle file in a project file, because there is insecure deserialization via the pickle.load(). Rated high severity (CVSS 7.8), this vulnerability is 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. Manuskript through 0.12.0 allows remote attackers to execute arbitrary code via a crafted settings.pickle file in a project file, because there is insecure deserialization via the pickle.load() function in settings.py. NOTE: the vendor's position is that the product is not intended for opening an untrusted project file Affected products include: Theologeek Manuskript. Version information: through 0.12.0.

RemediationAI
