CVE-2022-35961: @openzeppelin/contracts OpenZeppelin Contracts Vulnerable To ECDSA Vulnerability
HIGHCVE-2022-35961 is a HIGH (CVSS 7.9) openzeppelin contracts vulnerable to ecdsa vulnerability (CWE-354: Improper Validation of Integrity Check Value) affecting @openzeppelin/contracts libraries in the npm ecosystem. The issue involves openzeppelin contracts vulnerable to ecdsa signature malleability. Remediation is available by upgrading affected packages to version 4.7.3.
CVE-2022-35961 at a Glance
Security Impact
CVSS: 7.9
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:L).
How to Fix CVE-2022-35961
To remediate this vulnerability, upgrade all affected @openzeppelin/contracts dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @openzeppelin/contracts@4.7.3npm install @openzeppelin/contracts-upgradeable@4.7.3Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @openzeppelin/contractsHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2022-35961, inspect your project dependencies using npm:
npm ls @openzeppelin/contractsAnalyze the terminal output to locate any version of @openzeppelin/contracts in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.7.3), your application is affected.
Note: The npm ls @openzeppelin/contracts command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-354: Improper Validation of Integrity Check Value, where the product does not validate or incorrectly validates the integrity check values or "checksums" of a message. this may prevent it from detecting if the data has been modified or corrupted in transmission. In @openzeppelin/contracts, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"summary" : "OpenZeppelin Contracts vulnerable to ECDSA signature malleability",
"details" : "### Impact\n\nThe functions `ECDSA.recover` and `ECDSA.tryRecover` are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issue for the functions that take a single `bytes` argument, and not the functions that take `r, v, s` or `r, vs` as separate arguments.\n\nThe potentially affected contracts are those that implement signature reuse or replay protection by marking the signature itself as used rather than the signed message or a nonce included in it. A user may take a signature that has already been submitted, submit it again in a different form, and bypass this protection.\n\n### Patches\n\nThe issue has been patched in 4.7.3.\n\n\n### For more information\n\nIf you have any questions or comments about this advisory, or need assistance deploying a fix, email us at [security@openzeppelin.com](mailto:security@openzeppelin.com).\n",
