TITLE

Siemens LOGO! Soft Comfort Man-in-the-middle attack vulnerability

Trust: 0.8

sources: IVD: e2dfcf21-39ab-11e9-83c6-000c29342cb1 // CNVD: CNVD-2017-37691

DESCRIPTION

Siemens LOGO! Soft Comfort (All versions before V8.2) lacks integrity verification of software packages downloaded via an unprotected communication channel. This could allow a remote attacker to manipulate the software package while performing a Man-in-the-Middle (MitM) attack. Successfully exploiting this issue may allow attackers to bypass certain security restrictions and perform unauthorized actions by conducting a man-in-the-middle attack. This may lead to other attacks. Versions prior to LOGO! Soft Comfort 8.2 are vulnerable
