CVE-2022-31313: 
Python vulnerability analysis and mitigation

The api-res-py package version 0.1 in PyPI contains a code execution backdoor vulnerability (CVE-2022-31313). The vulnerability was discovered in May 2022 and is related to a malicious 'request' dependency included in the package (CVE Mitre, Bleeping Computer).

The vulnerability stems from the inclusion of a malicious 'request' dependency (without 's') instead of the legitimate 'requests' Python module. The malicious package contains base64-encoded URLs pointing to malware files: 'check.so' (a Remote Access Trojan) and 'x.pyx' (an info-stealer). The info-stealing component is designed to harvest cookies and personal information from various web browsers including Chrome, Firefox, Yandex, and Brave (Bleeping Computer).

When exploited, the backdoor allows attackers to access sensitive user information, steal login credentials and passwords stored in web browsers. The compromised credentials could potentially be used to compromise other developer accounts, leading to further supply-chain attacks (Bleeping Computer).

Users should ensure they are not using version 0.1 of the api-res-py package. The legitimate Python HTTP library is named 'requests' (with an 's'), and developers should verify they are using the correct package name in their dependencies (Bleeping Computer).
