CVE-2017-15698
5.9 · MEDIUMOverview
CVE-2017-15698 is a medium-severity vulnerability affecting apache tomcat_native. It was published on January 31, 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
When parsing the AIA-Extension field of a client certificate, Apache Tomcat Native Connector 1.2.0 to 1.2.14 and 1.1.23 to 1.1.34 did not correctly handle fields longer than 127 bytes. The result of the parsing error was to skip the OCSP check. It was therefore possible for client certificates that should have been rejected (if the OCSP check had been made) to be accepted. Users not using OCSP checks are not affected by this vulnerability.
Remediation
Check the references section for vendor advisories and patches from apache. Update tomcat_native 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.
