Last modified
CVE-2013-4347 is a vulnerability of currently unknown severity. The (1) make_nonce, (2) generate_nonce, and (3) generate_verifier 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.. EPSS estimates a 2.43% chance of exploitation in the next 30 days.
