Security readout for executives and security teams
CVE-2018-6562 affects totemomail Encryption Gateway before 6.0_b567. A remote attacker could use JSONP hijacking to obtain sensitive user-session information and encryption key material. For an email encryption gateway, exposure of key material can create serious confidentiality risk. Exposure is most likely where totemomail Encryption Gateway is deployed below 6.0_b567 and reachable by users through browsers. The bundle does not identify specific platforms, configurations, or internet-wide prevalence. Treat this as high priority if the product is present. The issue concerns session data and encryption key material, but public evidence in the bundle is incomplete on exploitation and exact remediation details. Mitigation focus: Identify any deployed totemomail Encryption Gateway instances and their exact build versions.; Upgrade affected installations to 6.0_b567 or later if vendor guidance confirms availability.; Review vendor advisory CSNC-2018-002 for product-specific remediation instructions..
