Mitsubishi MELSEC iQ-F CPU: Missing Authentication Flaw

⚠️ Mitsubishi Electric's MELSEC iQ-F Series CPU modules are affected by a Missing Authentication for Critical Function vulnerability (CVE-2025-7405) in Modbus/TCP that can allow remote attackers to read and write device values and potentially halt program execution. CISA assigns a CVSS v4 base score of 6.9 and notes the issue is remotely exploitable with low attack complexity. Mitsubishi reports many FX5U/FX5UC/FX5UJ/FX5S variants affected and currently has no fixed version planned. Recommended mitigations include network segmentation, VPNs or firewalls, IP filtering, and restricting physical access.

Schneider Electric Saitel RTU Privilege Escalation Advisory

⚠ Schneider Electric disclosed an improper privilege management vulnerability (CVE-2025-8453, CVSS 6.7) affecting Saitel DR and Saitel DP Remote Terminal Units that could allow an authenticated privileged engineer with console access to escalate privileges and potentially execute arbitrary code. Schneider released HUe firmware 11.06.30 for Saitel DR to remediate the issue; a remediation plan for Saitel DP is pending. CISA notes the vulnerability is not remotely exploitable and recommends limiting physical and console access, enforcing root ownership and restrictive permissions on configuration files, and following ICS defensive guidance.

Delta Electronics CNCSoft-G2: Out-of-Bounds Write Advisory

⚠️ Delta Electronics disclosed an CNCSoft-G2 out‑of‑bounds write vulnerability (CVE-2025-47728) in DPAX file parsing that can cause memory corruption and enable arbitrary code execution in the affected process. CISA assigns a CVSS v4 base score of 8.5 and notes low attack complexity but requires user interaction such as opening a malicious file or visiting a malicious page. Affected versions include v2.1.0.20 and earlier; Delta recommends updating to v2.1.0.27 or later per advisory Delta-PCSA-2025-00007. CISA advises applying the update, isolating control systems, avoiding untrusted attachments, and following ICS recommended practices; no public exploitation has been reported to date.

Citrix warns of NetScaler ADC/Gateway zero-day exploit

⚠️ Citrix has warned of multiple zero-day vulnerabilities in NetScaler ADC and NetScaler Gateway, highlighting CVE-2025-7775 as being actively exploited. The critical issue is a memory overflow that can lead to denial of service or remote code execution on appliances meeting specific configuration preconditions. Citrix provides CLI checks to identify affected devices but reports no mitigations or workarounds, and researchers estimate a large percentage of appliances remain unpatched. Administrators are urged to prioritize patching immediately.

Ten Vulnerabilities in Libbiosig and Multiple Vendors

🔒 Cisco Talos disclosed multiple vulnerabilities affecting libbiosig, Tenda AC6, SAIL, PDF‑XChange Editor, and Foxit PDF Reader. The flaws include integer overflows, heap and stack buffer overflows, out‑of‑bounds reads, authentication and firmware validation weaknesses, and other memory corruption issues that can lead to remote code execution or information disclosure. Vendors have released patches in coordination with Talos and Snort coverage is available to detect exploitation attempts. Apply vendor updates and detection rules immediately to reduce exposure.

BadCam: Reflashed Webcams Enable BadUSB-Style Attacks

🔒 Researchers demonstrated BadCam, a BadUSB-style attack presented at BlackHat that reflashes a webcam's firmware so a standard camera can act as a programmable HID device. The proof-of-concept targeted Lenovo 510 FHD and Lenovo Performance FHD models using a SigmaStar SoC, exploiting lack of cryptographic firmware verification and Linux USB Gadget support to present keyboard/network interfaces. Standard scans and OS reinstalls won't remove such implants, so organizations should apply firmware patches, USB control policies, and HID monitoring to mitigate the risk.

Citrix Patches NetScaler Zero-Days as Active Exploits Continue

🔒Citrix has released patches for three critical zero-day vulnerabilities in NetScaler ADC and NetScaler Gateway (CVE-2025-7775, CVE-2025-7776, CVE-2025-8424), including pre-auth remote code execution observed in the wild. The vendor provided fixes for affected 14.1, 13.1 and 12.1-FIPS/NDcPP builds and said no workaround is available. Security researchers and CISA urged immediate patching and forensic checks for potential backdoors.

Citrix Patches NetScaler Flaws; Confirms Active Exploitation

🔒 Citrix has issued patches for three vulnerabilities in NetScaler ADC and NetScaler Gateway, and confirmed active exploitation of CVE-2025-7775. The flaws include two memory overflow issues (CVSS 9.2 and 8.8) that can lead to remote code execution or denial-of-service, and an improper access-control bug (CVSS 8.7) affecting the management interface. Fixes are available in multiple 12.x–14.x releases with no workarounds; Citrix credited external researchers for reporting the issues.

Sni5Gect: Novel 5G Sniff-and-Inject Downgrade Attack

🔍 A research team at SUTD's ASSET group released Sni5Gect, an open-source over-the-air toolkit that passively sniffs early 5G signaling and injects crafted payloads before NAS security is established. The framework can crash UE modems, fingerprint devices, bypass some authentication flows, and force downgrades from 5G to 4G without deploying a rogue gNB, with reported injection success rates of 70–90% at up to 20 m. GSMA recorded the issue as CVD-2024-0096.

Schneider Electric Modicon M340: FTP Input Validation Flaw

⚠️ Schneider Electric disclosed an Improper Input Validation vulnerability in Modicon M340 controllers and several communication modules that can be triggered by a specially crafted FTP command. Tracked as CVE-2025-6625 with a CVSS v4 base score of 8.7, the flaw enables a remote denial-of-service with low attack complexity. Schneider released firmware fixes for the BMXNOE0100 (v3.60) and BMXNOE0110 (v6.80) modules, which require device reboot; remediation for other affected products is planned. CISA recommends disabling FTP when not needed, blocking or segmenting port 21, using VPNs for remote access, applying vendor updates where available, and following ICS hardening and risk-assessment practices before making changes.

INVT VT-Designer and HMITool Vulnerabilities Alert Issued

🔔 CISA warns of multiple memory-corruption vulnerabilities in INVT products VT-Designer (v2.1.13) and HMITool (v7.1.011). The flaws—several out-of-bounds writes and a type confusion bug—occur in PM3 and VPM file parsing and can enable arbitrary code execution in the vulnerable process. Issues are tracked as CVE-2025-7223 through CVE-2025-7231 with CVSS v4 scores up to 8.5. Exploitation requires user interaction, such as opening a crafted file.

CISA Issues Three Industrial Control Systems Advisories

🔔 CISA released three Industrial Control Systems advisories on August 26, 2025, detailing vulnerabilities and mitigations for INVT VT‑Designer and HMITool, Schneider Electric Modicon M340 controllers and modules, and an updated advisory for Danfoss AK‑SM 8xxA Series.

CISA Adds CVE-2025-7775 for Citrix NetScaler Memory Overflow

🔔 CISA has added CVE-2025-7775, a memory overflow vulnerability in Citrix NetScaler, to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation. This class of flaw is a frequent attack vector and presents significant risk to the federal enterprise. Under BOD 22-01, Federal Civilian Executive Branch agencies must remediate cataloged KEVs by the specified due date. CISA strongly urges all organizations to prioritize timely remediation as part of routine vulnerability management.

CISA Adds Three Actively Exploited Flaws in Citrix, Git

🚨 CISA added three vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog affecting Citrix Session Recording and Git. Two Citrix issues (CVE-2024-8068, CVE-2024-8069; CVSS 5.1) can lead to privilege escalation to the NetworkService account or limited remote code execution for authenticated intranet users, while CVE-2025-48384 (CVSS 8.1) in Git stems from carriage return handling that can enable arbitrary code execution. Federal agencies must mitigate these issues by September 15, 2025.

Docker fixes critical container escape CVE-2025-9074

🚨Docker has released an urgent patch for CVE-2025-9074, a critical container escape flaw in Docker Desktop for Windows and macOS that carries a CVSS score of 9.3. A malicious container could reach the Docker Engine API at 192.168.65.7:2375 without authentication, create and start new containers that bind the host C:\ drive and thereby access or modify host files. The issue is fixed in version 4.44.3; Enhanced Container Isolation (ECI) does not mitigate the vulnerability. Linux desktop installations are not affected because they use a host named pipe instead of a TCP socket.
