CISA Advisories

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2025-62593 Ray-Project Ray Code Injection 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) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.

View CSAF Summary Siemens LOGO! Soft Comfort contains multiple vulnerabilities in its project-file encryption and password handling mechanisms. A local attacker could exploit these vulnerabilities to extract the master key, allowing them to decrypt project data or remove project passwords. The lack of password salting enables offline dictionary or brute-force attacks against the password hashes. Successful exploitation could result in unauthorized access to, or modification of, sensitive project logic and configurations. Siemens has released a new version for LOGO! Soft Comfort and recommends to update to the latest version. The following versions of Siemens LOGO! Soft Comfort are affected: LOGO!

View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to decrypt sensitive data, bypass authentication controls, gaining unauthorized access to read arbitrary files on the system, or gain unauthorized access to protected system resources. The following versions of Johnson Controls Inc. Airwall are affected: Airwall <=4.0.4 (CVE-2026-64887, CVE-2026-34492) CVSS Vendor Equipment Vulnerabilities v3 6.8 Johnson Controls Inc. Johnson Controls Inc. Airwall Use of Hard-coded Cryptographic Key, External Control of File Name or Path Background Critical Infrastructure Sectors: Critical Manufacturing, Commercial Facilities, Government Services and Facilities, Transportation Systems, Energy Countries/Areas Deployed: Worldwide Company Headquarters Location: Ireland Vulnerabilities Expand All + CVE-2026-64887 A hardcoded password or cryptographic key was identified in the Airwall application. A hardcoded credential leads to a significant authentication failure that can be difficult for system or application administrators to detect. Once discovered, it is difficult to remediate without manually modifying or patching the software. The hardcoded key is identical across all installations of the product and across all customer organizations, meaning a single disclosure of the key - common on the internet - grants any knowledgeable attacker access to all affected deployments. An attacker with access to application code or binary files can use the hardcoded key to decrypt sensitive application data stored in configuration and database files, enabling further data disclosure or compromise of application infrastructure. View CVE Details Affected Products Johnson Controls Inc. Airwall Vendor: Johnson Controls Inc. Product Version: Johnson Controls Inc. Airwall: <=4.0.4 Product Status: known_affected Remediations Mitigation To help reduce risk of exploitation, Johnson Controls recommends the following defensive measures: Apply v4.1.0 or later patches for all Airwalls. Mitigation Store all cryptographic keys in a secure key management system (KMS) or hardware security module (HSM) rather than embedding them in source code or configuration files. (CVE-2026-64887) Mitigation Implement a regular key rotation policy to limit the exposure window if a key is compromised. (CVE-2026-64887) Mitigation Use unique cryptographic keys per device, installation, or deployment instance to prevent a single compromised key from affecting all installations. (CVE-2026-64887) Mitigation Remove any hard-coded keys from source code repositories and binaries, replacing them with references to secure external key stores. (CVE-2026-64887)Apply the principle of least privilege to key access, ensuring only authorized processes and personnel can retrieve cryptographic material. (CVE-2026-64887) Mitigation Use static analysis and secrets-scanning tools in CI/CD pipelines to detect and prevent hard-coded keys from being committed to source control. (CVE-2026-64887) Mitigation Encrypt keys at rest and in transit and ensure key-wrapping mechanisms are in place for any keys stored on disk. (CVE-2026-64887) Mitigation Audit and monitor access to cryptographic keys, logging all retrieval and usage events for anomaly detection.

This issue occurs when user-supplied input is directly incorporated into filesystem access functions without adequate validation or sanitization. As a result, an attacker can request and obtain the contents of arbitrary files on the server, including sensitive configuration files, source code, credential stores, and private keys, provided the application process has permission to read them. The vulnerability is commonly exploited through path traversal sequences (e.g., ../) or absolute file paths (e.g., /etc/passwd). Encoding variations of traversal sequences (e.g., %2e%2e%2f) can also bypass basic filters. View CVE Details Affected Products Johnson Controls Inc. Airwall Vendor: Johnson Controls Inc.
