Vulnerability from github – Published: 2019-02-18 23:39 – Updated: 2020-08-31 18:10

Summary

Timing Attack in csrf-lite

Details

Affected versions of csrf-lite are vulnerable to timing attacks as a result of testing CSRF tokens via a fail-early comparison instead of a constant-time comparison.

Timing attacks remove the exponential increase in entropy gained from increased secret length, by providing per-character feedback on the correctness of a guess via miniscule timing differences.

Under favorable network conditions, an attacker can exploit this to guess the secret in no more than (16*18)288 guesses, instead of the 16^18 guesses required were the timing attack not present.

Recommendation

Update to version 0.1.2 or later.

Vulnerability from cvelistv5 – Published: 2018-05-31 20:00 – Updated: 2024-09-17 01:30

Summary

csrf-lite is a cross-site request forgery protection library for framework-less node sites. csrf-lite uses `===`, a fail first string comparison, instead of a time constant string comparison This enables an attacker to guess the secret in no more than (16*18)288 guesses, instead of the 16^18 guesses required were the timing attack not present.
