CVE-2018-8023 (GCVE-0-2018-8023)

Vulnerability from cvelistv5 – Published: 2018-09-21 13:00 – Updated: 2024-09-16 16:58
VLAI?
Summary
Apache Mesos can be configured to require authentication to call the Executor HTTP API using JSON Web Token (JWT). In Apache Mesos versions pre-1.4.2, 1.5.0, 1.5.1, 1.6.0 the comparison of the generated HMAC value against the provided signature in the JWT implementation used is vulnerable to a timing attack because instead of a constant-time string comparison routine a standard `==` operator has been used. A malicious actor can therefore abuse the timing difference of when the JWT validation function returns to reveal the correct HMAC value.
