CVE-2023-30541 (GCVE-0-2023-30541)

Vulnerability from cvelistv5 – Published: 2023-04-17 21:37 – Updated: 2025-02-05 20:31

Title

TransparentUpgradeableProxy clashing selector calls may not be delegated in @openzeppelin/contracts

Summary

OpenZeppelin Contracts is a library for secure smart contract development. A function in the implementation contract may be inaccessible if its selector clashes with one of the proxy's own selectors. Specifically, if the clashing function has a different signature with incompatible ABI encoding, the proxy could revert while attempting to decode the arguments from calldata. The probability of an accidental clash is negligible, but one could be caused deliberately and could cause a reduction in availability. The issue has been fixed in version 4.8.3. As a workaround if a function appears to be inaccessible for this reason, it may be possible to craft the calldata such that ABI decoding does not fail at the proxy and the function is properly proxied through.

GHSA-MX2Q-35M2-X2RH

Vulnerability from github – Published: 2023-04-17 16:45 – Updated: 2023-04-18 16:14

Summary

OpenZeppelin Contracts TransparentUpgradeableProxy clashing selector calls may not be delegated

Details

Impact

A function in the implementation contract may be inaccessible if its selector clashes with one of the proxy's own selectors. Specifically, if the clashing function has a different signature with incompatible ABI encoding, the proxy could revert while attempting to decode the arguments from calldata.

The probability of an accidental clash is negligible, but one could be caused deliberately.

Patches

The issue has been fixed in v4.8.3.

Workarounds

If a function appears to be inaccessible for this reason, it may be possible to craft the calldata such that ABI decoding does not fail at the proxy and the function is properly proxied through.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
