7.8 · HIGHOverview
CVE-2018-5441 is a high-severity vulnerability affecting phoenixcontact mguard_centerport_firmware. It was published on January 30, 2018 and has a CVSS 3.0 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.0 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
An Improper Validation of Integrity Check Value issue was discovered in PHOENIX CONTACT mGuard firmware versions 7.2 to 8.6.0. mGuard devices rely on internal checksums for verification of the internal integrity of the update packages. Verification may not always be performed correctly, allowing an attacker to modify firmware update packages.
Remediation
Check the references section for vendor advisories and patches from phoenixcontact. Update mguard_centerport_firmware 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.
