An exponential ReDoS (Regular Expression Denial of Service) vulnerability in the snowflake-connector-python PyPI package could allow an attacker to trigger a DoS condition by supplying arbitrary input to a specific method.
Understanding CVE-2022-42965
This section provides an overview of the CVE-2022-42965 vulnerability.
What is CVE-2022-42965?
The CVE-2022-42965 vulnerability involves an exponential ReDoS vulnerability in the snowflake-connector-python PyPI package. Attackers can exploit this issue by providing malicious input to a specific method.
The Impact of CVE-2022-42965
The impact of CVE-2022-42965 is the potential denial of service (DoS) condition that could be triggered due to the inefficient regular expression complexity handling in the snowflake-connector-python package.
Technical Details of CVE-2022-42965
In this section, we delve into the technical aspects of CVE-2022-42965.
Vulnerability Description
The vulnerability arises from the inadequate handling of regular expression complexity in the snowflake-connector-python package, allowing attackers to exploit this weakness for a DoS attack.
Affected Systems and Versions
The snowflake-connector-python package versions prior to 2.8.2 are affected by this vulnerability, with the unspecified version categorized under the 'custom' version type.
Exploitation Mechanism
Attackers can exploit this vulnerability by providing arbitrary input to the undocumented get_file_transfer_type method, leading to the trigger of an exponential ReDoS condition.
Mitigation and Prevention
This section outlines the steps to mitigate and prevent exploitation of CVE-2022-42965.
Immediate Steps to Take
Developers and users are advised to update the snowflake-connector-python package to version 2.8.2 or newer to mitigate the risk of exploitation.
