SSA-840188SSA-840188: Multiple Vulnerabilities in SIMATIC WinCC Affecting Other SIMATIC Software Products2021-11-09csaf · siemens_psirtDE
Multiple vulnerabilities were found in SIMATIC WinCC that ultimately could allow local or remote attackers to escalate privileges and read, write or delete critical files. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where updates are not, or not yet available. Note: The vulnerability CVE-2021-40359 is part of a shared component, used by various Siemens products (SIMATIC Communication Services - SCS). The installation of a fix version of any product also removes the vulnerability for other products on the same system, even if those products were not updated.
