Detailsinfo

A vulnerability, which was classified as problematic, has been found in Apache Mesos pre-1.4.2/1.5.0/1.5.1/1.6.0 on Executor HTTP API. Affected by this issue is the function validation of the component String Comparison. The manipulation as part of a JSON Web Token leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

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.

The bug was discovered 09/21/2018. The weakness was released 09/21/2018 (Website). The advisory is available at lists.apache.org. This vulnerability is handled as CVE-2018-8023 since 03/08/2018.
