Vulnerabilities in this advisory
- CVE-2015-1355 · CWE-916
Siemens SIMATIC STEP 7 (TIA Portal) before 13 SP1 uses a weak password-hash algorithm, which makes it easier for local users to determine cleartext passwords by reading a project file and conducting a brute-force attack.
- CVE-2015-1356 · CWE-305
Siemens SIMATIC STEP 7 (TIA Portal) before 13 SP1 determines a user's privileges on the basis of project-file fields that lack integrity protection, which allows remote attackers to establish arbitrary authorization data via a modified file.
