Vulnerability from variot

A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.X (All versions < V9.1 SP2), SIMATIC PDM (All versions < V9.2 SP2), SIMATIC STEP 7 V5.X (All versions < V5.7), SINAMICS STARTER (containing STEP 7 OEM version) (All versions < V5.4 SP2 HF1). A directory containing metafiles relevant to devices' configurations has write permissions. An attacker could leverage this vulnerability by changing the content of certain metafiles and subsequently manipulate parameters or behavior of devices that would be later configured by the affected software. Multiple Siemens products are vulnerable to improper assignment of permissions to critical resources.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Siemens SIMATIC PCS 7 is a set of process control system of Germany Siemens (Siemens) company. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements

A directory containing metafiles relevant to devices\u0027 configurations has write permissions. An attacker could leverage this vulnerability by changing the content of certain metafiles and subsequently manipulate parameters or behavior of devices that would be later configured by the affected software. Multiple Siemens products are vulnerable to improper assignment of permissions to critical resources.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Siemens SIMATIC PCS 7 is a set of process control system of Germany Siemens (Siemens) company. Pillow is a Python-based image processing library. \nThere is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements",
