View CSAF Summary The SICAM SIAPP SDK contains multiple vulnerabilities that could allow an attacker to disrupt the customer-developed SIAPP or its simulation environment. Potential impacts include denial of service within the SIAPP, corruption of SIAPP data, or exploit the simulation environment. These vulnerabilities are only exploitable if the API is used improperly or hardening measures are not applied. Siemens has released a new version for SICAM SIAPP SDK and recommends to update to the latest version.

Maxime Rossi Bellom of Secmate reported these vulnerabilities to Siemens. General Recommendations 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's reliability can thus be minimized by virtue of the grid design. Siemens 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. As 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. Recommended security guidelines can be found at: https://www.siemens.com/gridsecurity Additional Resources For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories Terms of Use The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use.

An expensive mistake: Someone jumped at the opportunity to steal $4.4 million in crypto assets after South Korea’s National Tax Service exposed publicly the mnemonic recovery phrase of a seized cryptocurrency wallet. The funds were stored in a Ledger cold wallet seized in law enforcement raids at 124 high-value tax evaders that resulted in confiscating digital assets worth 8.1 billion won (currently approximately $5.6 million). When announcing the success of the operation, the agency released photos of a Ledger device, a popular hardware wallet for crypto storage and management. However, the images also showed a handwritten note of the wallet recovery phrase, which serves as the master key that allows restoring the assets to another device. The authorities failed to redact that info, allowing anyone to transfer into their account the assets in the cold wallet. Reportedly, shortly after the press release was published, 4 million Pre-Retogeum (PRTG) tokens, worth approximately $4.8 million at the time, were transferred out of the confiscated wallet to a new address.

CVE-2025-47813 Wing FTP Server Information Disclosure Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
