CVE-2018-8023
5.9 · MEDIUMOverview
CVE-2018-8023 is a medium-severity vulnerability affecting apache mesos. It was published on September 21, 2018 and has a CVSS 3.0 base score of 5.9 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 5.9, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from apache. Update mesos to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
