TITLE

Siemens SIMATIC STEP 7 TIA Portal Password Hash Algorithm Security Vulnerability

Trust: 1.0

sources: IVD: 98ae447c-2351-11e6-abef-000c29c66e3d // IVD: a22e1a1e-e3ad-4c1c-83cd-94c788acf76a // CNVD: CNVD-2015-01197

DESCRIPTION

Siemens SIMATIC STEP 7 (TIA Portal) 12 and 13 before 13 SP1 Upd1 improperly stores password data within project files, which makes it easier for local users to determine cleartext (1) protection-level passwords or (2) web-server passwords by leveraging the ability to read these files. (1) Protection level password, or (2) Web Server password may be specified. Siemens SIMATIC is an automation software in a single engineering environment. Siemens SIMATIC STEP 7 TIA Portal is prone to a security weakness due to insecure password-hash algorithm. Local attackers can exploit this issue to perform brute-force attacks and obtain user passwords which may aid in further attacks. Versions prior to Siemens SIMATIC STEP 7 TIA Portal V13 SP1 Upd1 are vulnerable. The software provides PLC programming, design option packages, advanced drive technology and more. A local attacker can exploit this vulnerability by reading a file to determine the plaintext protection-level or web-server password
