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.
