CISA Directs Agencies to Mitigate Cisco Device Risks

🚨 CISA issued Emergency Directive ED 25-03 directing federal agencies to identify, analyze, and mitigate potential compromises of Cisco ASA and Cisco Firepower devices after adding CVE-2025-20333 and CVE-2025-20362 to the Known Exploited Vulnerabilities Catalog. Agencies must inventory all devices (all versions) and collect memory/core dump files for forensic analysis, transmitting them to CISA by 11:59 p.m. EST on Sept. 26. CISA published supplemental guidance, an Eviction Strategies Tool template, and referenced Cisco and UK NCSC analyses to support containment, eviction, and remediation.

Cisco: Actively Exploited SNMP Flaw Risks RCE or DoS

🔒 Cisco has issued an urgent advisory about a high-severity SNMP vulnerability (CVE-2025-20352, CVSS 7.7) in IOS and IOS XE Software that has been exploited in the wild. The flaw is a stack overflow in the SNMP subsystem that can allow an authenticated remote attacker to cause a denial-of-service or, with higher privileges, execute arbitrary code as root. Exploitation requires SNMP community strings or valid SNMPv3 credentials and, for code execution, administrative (privilege 15) access. Cisco called out affected devices including Meraki MS390 and Catalyst 9300 series running Meraki CS 17 and earlier, and issued a fix in IOS XE 17.15.4a. There are no full workarounds; administrators should restrict SNMP access, monitor with "show snmp host", and consider excluding affected OIDs where supported.

New Supermicro BMC Flaws Enable Persistent Backdoors

🔐 Researchers from Binarly disclosed multiple firmware vulnerabilities in Supermicro Baseboard Management Controllers (BMCs) that allow attackers to load unofficial images and install persistent backdoors. A bypass for a previously patched issue (CVE-2024-10237) and a new flaw (CVE-2025-6198) let adversaries manipulate signed regions so digests and signatures still validate. A related confirmed issue is tracked as CVE-2025-7937. Supermicro has released firmware updates; administrators must identify affected models and apply fixes promptly.

SystemBC Turns Compromised VPS into High-Capacity Proxy

🔎 Researchers at Lumen Technology’s Black Lotus Labs say the SystemBC proxy botnet actively targets commercial VPS instances worldwide to build a high-capacity proxy network. The operation averages about 1,500 bots daily, relies on more than 80 C2 servers, and primarily exploits unpatched systems that often contain dozens of vulnerabilities. Customers and operators exhibit poor operational security, and the service is used by ransomware groups and third-party proxy resellers.

Critical Code-Execution CVEs Found in Chaos-Mesh Platform

⚠️ JFrog Security Research disclosed multiple CVEs in Chaos-Mesh, including three critical flaws that permit in-cluster attackers to execute arbitrary code on any pod. The Chaos Controller Manager exposes an unauthenticated ClusterIP GraphQL /query endpoint on port 10082 by default, enabling mutations such as killProcesses and cleanTcs. The critical issues (CVSS 9.8) arise from unsafe command construction in resolvers and an ExecBypass routine that allows OS command injection. Operators should upgrade to Chaos-Mesh 2.7.3 immediately; as a temporary mitigation redeploy the Helm chart with the control server disabled.

Yurei Ransomware Uses Open-Source Tools for Extortion

🔒 A newly identified ransomware group called Yurei is conducting double-extortion attacks, encrypting files and exfiltrating sensitive data before demanding payment. First observed by Check Point Research on September 5, Yurei has targeted organizations in Sri Lanka, India and Nigeria and may have ties to Morocco. Built largely from open-source Prince-Ransomware code, the malware encrypts each file using per-file ChaCha20 keys protected with ECIES, appending a .Yurei extension, and attempts to provide a ransom page and .onion contact. Although the early variant omits some operational features (for example it fails to set a ransom wallpaper and does not remove Windows shadow copies), the group still threatens publication of stolen data to pressure victims.
