Summary

CVE-2023-0297 is a critical-severity Code Injection (CWE-94) vulnerability in Pyload Pyload. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

CVE-2023-0297 is a code injection vulnerability, tracked under CWE-94, that affects the pyLoad download manager in the pyload/pyload GitHub repository prior to version 0.5.0b3.dev31. The flaw received a CVSS 3.1 score of 9.8, reflecting network-accessible attack vectors that require no authentication or user interaction and can impact confidentiality, integrity, and availability.

An unauthenticated attacker can supply crafted input that results in arbitrary Python code execution on the server. Public proof-of-concept material demonstrates remote code execution by abusing the js2py component, allowing an adversary to run operating-system commands or install persistent implants without prior credentials.

The referenced GitHub commit 7d73ba7919e594d783b3411d7ddb87885aea782d implements the fix, and the project released version 0.5.0b3.dev31 to address the issue. Multiple PacketStorm entries and the huntr.dev bounty report document working exploits and recommend immediate upgrade for any deployment still running an affected build.

EPSS scores remain elevated, with a current value of 0.9294 and a recorded peak of 0.9486, indicating sustained exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
