Short explanation
labbench before version 0.46.1 contains a deserialization of untrusted data vulnerability in read() and read_relational() functions. This flaw allows arbitrary code execution via specially crafted data files.
This vulnerability enables attackers to execute arbitrary code when users load data files with specific extensions, directly compromising system integrity and security.
What should be done?
- Update labbench to the latest version
- Follow vendor advisories for updates
Chain of evidence and sources
labbench 0.46.1 öncesi sürümlerde güvenilmeyen verilerin seri durumdan çıkarılması zafiyeti bulunmaktadır.
Zafiyet, .p veya .pickle uzantılı dosyaların pandas.read_pickle fonksiyonuna yönlendirilmesinden kaynaklanır.
Show the technical text from the sources
labbench before 0.46.1 contains a deserialization of untrusted data vulnerability in read() and read_relational() that passes any file with a .p or .pickle extension to pandas.read_pickle based on the extension alone. Attackers who supply a crafted data file or relational data archive can execute arbitrary code when a user loads it with these functions.
