CVE-2023-41419
Privilege Escalation vulnerability in gevent (PyPI)
What is CVE-2023-41419 About?
An issue in Gevent before version 23.9.0 allows a remote attacker to escalate privileges. This is achieved via a crafted script submitted to the WSGIServer component, which can lead to unauthorized elevated access. The exploit is remote and likely of moderate complexity due to the need for a crafted script.
Affected Software

- <23.9.0
Technical Details
Gevent, in versions prior to 23.9.0, contains a vulnerability within its WSGIServer component that allows for privilege escalation. An attacker can submit a specially crafted script or payload to the WSGIServer. The exact mechanism could involve improper handling of server-side script execution, unsanitized input used in dynamic code generation, or a flaw in how the WSGIServer executes or interprets certain requests. This crafted input, when processed by the vulnerable component, allows the attacker to execute code with elevated privileges, potentially gaining control over the server process or the underlying system.
What is the Impact of CVE-2023-41419?
Successful exploitation may allow attackers to escalate privileges on the affected system, gaining unauthorized access to sensitive resources, executing arbitrary code, or taking full control over the compromised server. This can lead to a complete compromise of data confidentiality, integrity, and availability.
What is the Exploitability of CVE-2023-41419?
Exploitation requires crafting a specific script or payload and delivering it to the vulnerable WSGIServer component remotely. The complexity is likely moderate due to the need to understand the server's processing logic and craft an effective script that can achieve privilege escalation. Authentication requirements are not explicitly stated, but often, privilege escalation vulnerabilities might require some initial level of access or interaction with the server, though not necessarily full authentication to a user account. The attack is remote. Special conditions involve the precise crafting of the script and its successful submission to the WSGIServer. Risk factors include exposure of the WSGIServer to untrusted input and insufficient input validation or sandboxing mechanisms.
