Vulnerability from variot
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
