CVE-2023-36665
Google Protobufjs Prototype Pollution
Description

"protobuf.js (aka protobufjs) 6.10.0 through 7.x before 7.2.5 allows Prototype Pollution, a different vulnerability than CVE-2022-25878. A user-controlled protobuf message can be used by an attacker to pollute the prototype of Object.prototype by adding and overwriting its data and functions. Exploitation can involve: (1) using the function parse to parse protobuf messages on the fly, (2) loading .proto files by using load/loadSync functions, or (3) providing untrusted input to the functions ReflectionObject.setParsedOption and util.setProperty.

Common Attack Pattern Enumeration and Classification (CAPEC)

We scan GitHub repositories to detect new proof-of-concept exploits. Following list is a collection of public exploits and proof-of-concepts, which have been published on GitHub (sorted by the most recently updated).

Malicious-ONNX is a proof-of-concept (PoC) demonstrating how ONNX model files can be weaponized using metadata-based payload injection. The attack leverages the metadata_props field to embed an obfuscated Python-based script, enabling remote code execution (RCE) and data exfiltration upon model loading.
