Dutch NCSC: Critical Check Point VPN flaws exploitation is imminent

Dutch NCSC warns exploitation is imminent for critical Check Point VPN RCE flaws CVE-2026-85102 and CVE-2026-85103, urging immediate patching of Security Gateways.

The Dutch NCSC assesses the likelihood and impact of exploitation as high for two critical Check Point VPN flaws, though no public PoC exploit has been reported. CVE-2026-85102 is improper validation of certificate data during VPN negotiation, and CVE-2026-85103 is a heap overflow in the VPN certificate ASN.1 decoder; both enable remote code execution on Security Gateways, the latter also on Security Management Servers. Affected releases span R81.20, R82, R82.10, R81.10.x, R82.00.x and EoS versions R80 through R81.10, while R82.20 is unaffected. Check Point shipped fixes on September 9 via LivePatch Take 24 and Jumbo Hotfix Accumulator takes, and NCSC advises restricting Site-to-Site VPN rules to trusted IPs.

CVE-2026-76461: Critical Cisco Secure Email Gateway Vulnerability Exploited in the Wild

Cisco Secure Email Gateway zero-day CVE-2026-76461 (CVSS 9.8) enables unauthenticated root command execution via crafted email; CISA added it to KEV.

CVE-2026-76461 is a critical SQL injection (CVSS 9.8) in Cisco AsyncOS for Secure Email Gateway allowing an unauthenticated remote attacker to execute arbitrary commands with root privileges by sending a specially crafted email through a vulnerable gateway. CISA added it to the KEV catalog on disclosure day, indicating zero-day exploitation, and Cisco PSIRT became aware of active exploitation in September 2026. No public PoC or attribution exists; fixed versions are 15.5.5-014, 16.0.4-302, and 16.5.0-780, and admins should check mail_logs for suspicious SQL statements like 'COPY.*TO PROGRAM'.

Cisco confirms CVE-2026-20079 Secure FMC flaw exploited in attacks

Cisco confirmed active exploitation of CVE-2026-20079, a CVSS 10.0 authentication bypass enabling unauthenticated root command execution in Secure FMC; CISA added it to KEV.

Cisco confirmed in August 2026 that CVE-2026-20079 (CVSS 10.0), an unauthenticated authentication bypass in Secure Firewall Management Center, is being actively exploited, allowing remote attackers to execute scripts and commands as root via crafted HTTP requests to the web interface. CISA added the flaw to its Known Exploited Vulnerabilities catalog, ordering federal civilian agencies to patch by September 12, 2026. Shared IOCs, identical hot fixes, and a July 23 log entry suggest CVE-2026-20079 was used alongside the separately exploited static-credential flaw CVE-2026-20316 in the same attacks. Cisco released patches and cloud fixes, warns hot fixes do not remediate already-compromised devices, and says there are no workarounds.

VU#431093: TCG TPM 2.0 reference code found vulnerable to information leakage and timing side-channel attacks

CERT/CC discloses two TPM 2.0 reference code flaws allowing RSA key decryption and forged TPM attestations via crafted commands.

CERT/CC published VU#431093 covering two vulnerabilities in the TCG TPM 2.0 reference implementation: CVE-2026-6726 (information leakage via falsified TPM keys) and CVE-2026-6727 (timing side-channel in RSA OAEP decryption). An attacker with privileged access to a TPM command interface could send crafted TPM commands to decrypt ciphertexts for affected TPM-managed RSA keys, including the RSA Endorsement Key, or obtain credentials enabling forged TPM 2.0 attestations. Remediation is tracked in TCGVRT010 and TCGVRT0011.

Wärtsilä FOS-Onboard

CISA advisory: two hardcoded cryptographic key flaws in Wärtsilä FOS-Onboard 5.07.0923.01 (CVSS 9.0/9.1) could allow unauthorized updates, code execution, and credential theft.

CISA advisory ICSA-26-258-02 discloses CVE-2026-78225 (CVSS 3.1 9.0 critical), a hardcoded cryptographic server key in the deployer-ng Update Controller of Wärtsilä FOS-Onboard 5.07.0923.01. CVE-2026-81855 (CVSS 3.1 9.1 critical) is a hardcoded client authentication key in the robot testing framework component. Successful exploitation could let an attacker deliver unauthorized updates, execute code, or extract credentials to impersonate a privileged client. The product is deployed worldwide in transportation systems critical infrastructure; Cydome Security reported the flaws and CISA states no known public exploitation exists.

VU#212479: Sentry Seer vulnerability allows attacker-controlled input to be executed in a privileged environment

CERT/CC details CVE-2026-90999: attacker-controlled Sentry telemetry can steer the Seer coding agent into executing attacker code with repository access.

CERT/CC published VU#212479 for CVE-2026-90999 in Sentry Seer: attacker-submitted events through public DSN endpoints flow into Seer's root-cause analysis, which is embedded directly into the coding agent's initial prompt. In the documented chain, the privileged coding agent downloads and executes an attacker-controlled package before any human review, yielding arbitrary code execution with access to connected source repositories. No vendor patch is available yet; mitigations include disabling automated remediation, restricting coding-agent package installation, and filtering telemetry before Seer analysis.

Cisco Fixed Critical RCE in Nexus 9000 Series Switches

Cisco patched CVE-2026-20212 (CVSS 9.8) in Silicon One-based Nexus 9000 switches, allowing unauthenticated remote root code execution via TCP ports 43210/43211.

Cisco patched CVE-2026-20212 (CVSS 9.8), a flaw in the Silicon One integration for Nexus 9000 Series switches that lets unauthenticated remote attackers execute code with root privileges. TCP ports 43210 and 43211 are exposed through the default Layer 3 VRF, and exploitation can also crash the S1HAL process, forcing device reloads. Cisco TAC discovered the flaw during a support case; PSIRT is not aware of public disclosure or malicious exploitation. Workarounds include infrastructure ACLs or blocking the exposed ports, alongside a Live Protect shield pending fixed NX-OS upgrades.

Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.

Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.

ASUS Control Center Critical Flaw Allows Unauthenticated Attackers to Gain Root Access

ASUS patched CVE-2026-19397 (CVSS 7.7) in Control Center Express Agent, letting unauthenticated nearby attackers with an active session take over the host.

ASUS released version 1.7.24 of Control Center Express Agent to fix CVE-2026-19397, a CWE-306 missing-authentication flaw scored 7.7 on CVSS v4. Exploitation requires an active login session on the target and nearby network access, and agent compromise could lead to complete device takeover where the agent runs with elevated privileges. ASUS also issued a same-day advisory for Armory Crate covering ten additional CVEs.

VU#456290: Hugging Face Transformers library writes remote code to disk prior to consent check

CVE-2026-80047: Hugging Face Transformers 4.49.0 through 5.8.1 writes attacker-controlled Python files to disk before the trust_remote_code consent check.

CERT/CC vulnerability note VU#456290 describes CVE-2026-80047 in the Hugging Face Transformers library, affecting versions 4.49.0 through 5.8.1. The library performs a remote module fetch and writes attacker-controlled Python files to the local disk before evaluating the trust_remote_code consent prompt, without user authorization. This violates the security contract enforced across other dynamic module-loading paths in the library. Transformers is a primary framework for training and inference across NLP, vision, audio, video, and multimodal machine learning systems.
