CVE-2013-4347 · GHSA-rv8h-p43r-4x5r
- Affected
- PyPI oauth2 < 1.9rc1
- Fixed in
- 1.9rc1· Vendor fix available
- Issue
- The (1) makenonce, (2) generatenonce, and (3) generateverifier functions in SimpleGeo python-oauth2 uses weak random numbers to generate nonces, which makes it easier for remote attackers to guess the nonce via a brute force attack.
Recommended action: Upgrade to 1.9rc1 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
