        "text": "SIPROTEC 5 is vulnerable to arbitrary file uploads by authenticated users using the DIGSI 5 protocol.\nThis could allow an attacker to upload malicious configuration files, potentially causing a permanent denial of service condition.\n\nAs a mitigation measure, users of the CP050 and CP150 device models are advised to upgrade to version 9.90 or later. For CP300 device models, devices 7ST85 and 7ST86 are advised to upgrade to version 10.00 or later, while the remaining models should upgrade to version 9.90 or later. These versions introduce an allow-list feature that restricts arbitrary file uploads and reduces the risk associated with this vulnerability.\n\nSiemens is preparing fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.",

        "text": "Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid\u0027s reliability can thus be minimized by virtue of the grid design.\nSiemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. \nAs a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment.\n\nRecommended security guidelines can be found at:\nhttps://www.siemens.com/gridsecurity",
