⚠️ Oracle has warned customers that attackers may be exploiting unpatched instances of Oracle E-Business Suite, following alerts from the Google Threat Intelligence Group and reports of extortion emails sent to company executives. The vendor’s investigation points to vulnerabilities addressed in the July 2025 Critical Patch Update, and it urges organizations to apply those fixes immediately. The July update fixed nine EBS flaws, including three critical issues and several that can be exploited remotely without authentication, raising urgent remediation priorities for affected deployments. Security teams should verify patch status, hunt for indicators of compromise, and validate account integrity.

⚠️More than 48,800 internet-exposed Cisco ASA and FTD appliances remain vulnerable to two remotely exploitable flaws, CVE-2025-20333 and CVE-2025-20362, that allow arbitrary code execution and access to restricted VPN endpoints. Cisco confirmed active exploitation began before patches were available and no workarounds exist. Administrators should restrict VPN web interface exposure, increase logging and monitoring for suspicious VPN activity, and apply vendor fixes immediately.

⚠ CISA warns that a critical sudo vulnerability (CVE-2025-32463) is being actively exploited to gain root privileges on Linux systems. The flaw affects sudo versions 1.9.14 through 1.9.17 and can be abused via the -R (--chroot) option to run arbitrary commands as root even for users not listed in sudoers. A proof-of-concept was published in early July and CISA has added the issue to its KEV catalog, requiring federal mitigations by October 20 or discontinuation of sudo.

⚠️ NVISO Labs says China-linked UNC5174 has been exploiting a newly patched local privilege escalation bug, CVE-2025-41244, in Broadcom VMware Tools and VMware Aria Operations since mid-October 2024. The vulnerability (CVSS 7.8) stems from a vulnerable get_version() regex that can match non-system binaries in writable directories (for example, /tmp/httpd) and cause metrics collection to execute them with elevated privileges. VMware and Broadcom have released fixes and mitigations; affected organizations should apply vendor patches and follow VMware's guidance, and Linux distributions will receive patched open-vm-tools packages from vendors.

🔒 LockBit 5.0 introduces faster ESXi drive encryption and enhanced evasion techniques, according to Trend Micro.

Researcher Jon DiMaggio describes the update as largely incremental fine-tuning and self-branding aimed at restoring affiliate trust after Operation Cronos.

⚠️ Cisco reported active exploitation of multiple zero-day vulnerabilities in ASA and FTD software by a state-sponsored actor tracked as ArcaneDoor. Two CVEs (CVE-2025-20333 and CVE-2025-20362) are being exploited in the wild and a third (CVE-2025-20363) is at high risk for imminent exploitation. Cisco released updates on Sep. 25, 2025, and CISA issued Emergency Directive 25-03; organizations should prioritize immediate patching or apply vendor mitigations when updates are not yet possible.

⚠️ Fortra's GoAnywhere MFT is being exploited in the wild via a deserialization flaw tracked as CVE-2025-10035 in the License Servlet, enabling unauthenticated remote command injection when attackers supply a forged license response signature. WatchTowr Labs reports credible evidence of exploitation dating back to September 10, 2025, prior to Fortra's advisory published on September 18. Administrators should apply patches to 7.8.4 or 7.6.3, remove public Admin Console exposure, and search logs for the error string 'SignedObject.getObject'.

🔒 Cisco has linked a renewed campaign exploiting Cisco ASA 5500-X devices to the espionage-focused ArcaneDoor threat actor. The operation leveraged zero-day flaws, notably CVE-2025-20333 and CVE-2025-20362, to implant malware, modify ROMMON for persistence and evade detection by disabling logging and intercepting CLI commands. Observed compromises affected older ASA models lacking Secure Boot/Trust Anchor protections; Cisco and national authorities urge immediate remediation. Temporary mitigations include disabling SSL/TLS VPN web services and IKEv2 client services while applying vendor fixes and conducting forensics.

🔴 watchTowr Labs reports credible evidence that the critical unsafe deserialization flaw CVE-2025-10035 in Fortra GoAnywhere MFT was exploited in the wild as early as Sept 10, 2025, a week before public disclosure. The License Servlet vulnerability can permit unauthenticated command injection, earning a CVSS 10.0 rating. Fortra has released fixes (GoAnywhere 7.8.4 and Sustain 7.6.3); affected organizations should apply updates immediately and investigate for signs of compromise.

🛡️ The U.K. NCSC and Cisco confirmed active exploitation of recently disclosed vulnerabilities in Cisco Secure Firewall ASA devices that allowed deployment of previously undocumented malware families, notably RayInitiator and LINE VIPER. Cisco traced attacks beginning in May 2025 that targeted ASA 5500‑X appliances (running ASA 9.12/9.14 with VPN web services enabled), using multiple zero-day flaws to bypass authentication and execute code. Attackers employed a persistent GRUB bootkit, ROMMON modifications on non‑Secure Boot platforms, and extensive evasion techniques — disabling logging, intercepting CLI, and crashing devices — to maintain stealth and persistence. Organizations are urged to apply vendor fixes, migrate off end‑of‑support models, and monitor for indicators of compromise.

⚠️ Cisco has warned of a stack overflow vulnerability in the SNMP subsystem of IOS and IOS XE software identified as CVE-2025-20352. A low-privileged authenticated attacker can send a crafted SNMP packet to cause a system reload and a denial-of-service, while a high-privileged actor could achieve root-level arbitrary code execution. Administrators are urged to apply vendor patches immediately and restrict SNMP access until systems are updated.

⚠️ Cisco is urging customers to immediately patch two zero-day vulnerabilities affecting the VPN web server in Cisco Secure Firewall Adaptive Security Appliance (ASA) and FTD software after observing exploitation in the wild. CVE-2025-20333 (CVSS 9.9) allows an authenticated VPN user to execute arbitrary code as root; CVE-2025-20362 (CVSS 6.5) permits unauthenticated access to restricted URL endpoints. CISA has issued Emergency Directive ED 25-03, added both flaws to the Known Exploited Vulnerabilities catalog with a 24-hour mitigation requirement, and warned of a widespread campaign linked to the ArcaneDoor/UAT4356 cluster that can modify ASA ROM to persist.

⚠️ Cisco has warned customers of two actively exploited zero-day vulnerabilities affecting Adaptive Security Appliance (ASA) and Firewall Threat Defense (FTD) software. CVE-2025-20333 enables authenticated attackers to execute arbitrary code remotely, while CVE-2025-20362 allows remote access to restricted URL endpoints without authentication. Cisco's PSIRT reported attempted exploitation and strongly recommends upgrading to fixed software releases.

🚨 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 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.

🔐 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.

🔒 The municipality of Hoppegarten in Brandenburg is still recovering from a hacker attack that forced its IT systems to be shut down on August 10.
