Overview

CVE-2016-8217 is a low-severity vulnerability. It was published on February 3, 2017 and has a CVSS 3.1 base score of 3.7 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.7, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

EMC RSA BSAFE Crypto-J versions prior to 6.2.2 has a PKCS#12 Timing Attack Vulnerability. A possible timing attack could be carried out by modifying a PKCS#12 file that has an integrity MAC for which the password is not known. An attacker could then feed the modified PKCS#12 file to the toolkit and guess the current MAC one byte at a time. This is possible because Crypto-J uses a non-constant-time method to compare the stored MAC with the calculated MAC. This vulnerability is similar to the issue described in CVE-2015-2601.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
