When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member would still be extracted and not skipped.
A flaw was found in CPython's tarfile module. This vulnerability allows unauthorized file extraction via crafted tar archives when TarFile.errorlevel=0, bypassing expected filtering mechanisms.
Отчет
The severity of this vulnerability was lowered due to the fact that successful exploitation requires the attacker to convince a privileged user or process to extract a malicious tar file. Since tar file extraction typically occurs in trusted contexts or with elevated privileges, the impact is reduced by the requirement of such access. Versions of python36:3.6/python36 as shipped with Red Hat Enterprise Linux 8 are marked as 'Not affected' as they just provide "symlinks" to the main python3 component, which provides the actual interpreter of the Python programming language. Within regulated environments, a combination of the following controls acts as a significant barrier to successful exploitation of a CWE-706: Use of Incorrectly-Resolved Name or Reference and therefore downgrades the severity of this particular CVE from Moderate to Low. Access enforcement and least privilege limit resolution of internal objects and services to explicitly authorized users and processes, reducing the risk of unintended interactions.. Configuration settings are tightly managed to ensure consistent and accurate resolution of names, paths, and references across deployments. Least functionality reduces exposure by disabling unused features and restricting access to unnecessary components. Additionally, real-time monitoring detects anomalous behavior or access attempts involving misconfigured or invalid references, enabling timely response and containment.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
