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. Se ha identificado una vulnerabilidad en SIMATIC PCS 7 V8.2 y anteriores (Todas las versiones), SIMATIC PCS 7 V9.X (Todas las versiones anteriores a V9.1 SP2), SIMATIC PDM (Todas las versiones anteriores a V9.2 SP2), SIMATIC STEP 7 V5.X (Todas las versiones anteriores a V5.7), SINAMICS STARTER (que contiene la versión OEM de STEP 7) (Todas las versiones anteriores a V5.4 SP2 HF1). Un directorio que contiene metafichas relevantes para las configuraciones de los dispositivos tiene permisos de escritura. • https://cert-portal.siemens.com/productcert/pdf/ssa-661034.pdf • CWE-732: Incorrect Permission Assignment for Critical Resource •

A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3), SIMATIC PDM (All versions < V9.2), SIMATIC STEP 7 V5.X (All versions < V5.6 SP2 HF3), SINAMICS STARTER (containing STEP 7 OEM version) (All versions < V5.4 HF2). The affected software contains a buffer overflow vulnerability while handling certain files that could allow a local attacker to trigger a denial-of-service condition or potentially lead to remote code execution. Se ha identificado una vulnerabilidad en SIMATIC PCS 7 versiones V8.2 y anteriores (Todas las versiones), SIMATIC PCS 7 versiones V9.0 (Todas las versiones anteriores a V9.0 SP3), SIMATIC PDM (Todas las versiones anteriores a V9.2), SIMATIC STEP 7 versiones V5.X (Todas las versiones anteriores a V5.6 SP2 HF3), SINAMICS STARTER (que contiene la versión OEM de STEP 7) (Todas las versiones anteriores a V5.4 HF2). El software afectado contiene una vulnerabilidad de desbordamiento de búfer mientras se manejan determinados archivos que podría permitir a un atacante local desencadenar una condición de denegación de servicio o potencialmente conllevar a una ejecución de código remota • https://cert-portal.siemens.com/productcert/pdf/ssa-641963.pdf • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3), SIMATIC PDM (All versions < V9.2), SIMATIC STEP 7 V5.X (All versions < V5.6 SP2 HF3), SINAMICS STARTER (containing STEP 7 OEM version) (All versions < V5.4 HF2). A buffer overflow vulnerability could allow a local attacker to cause a Denial-of-Service situation. The security vulnerability could be exploited by an attacker with local access to the affected systems. Successful exploitation requires user privileges but no user interaction. The vulnerability could allow an attacker to compromise the availability of the system as well as to have access to confidential information. • https://cert-portal.siemens.com/productcert/pdf/ssa-689942.pdf https://us-cert.cisa.gov/ics/advisories/icsa-20-161-05 https://www.us-cert.gov/ics/advisories/icsa-20-161-05 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
