Vulnerability CVE-2021-43298
Published: 2022-01-25
| Description: |
The code that performs password matching when using 'Basic' HTTP authentication does not use a constant-time memcmp and has no rate-limiting. This means that an unauthenticated network attacker can brute-force the HTTP basic password, byte-by-byte, by recording the webserver's response time until the unauthorized (401) response. |
Type:
CWE-307 (Improper Restriction of Excessive Authentication Attempts)
