![]() ![]() Vulnerable Products: Any Cisco switch, router, or wireless LAN controller running IOS XE with the HTTP or HTTPS Server feature enabled and exposed online. The implant is temporary, being eliminated upon reboot, but created user accounts persist. Upon exploitation, attackers have primarily been deploying an implant, enabling them to run malicious commands. Impact: Allows attackers to create an admin-level account, granting them full control of the compromised device.Įxploitation: Active exploitation has been observed since at least September 18. Severity Rating: 10 out of 10 – the highest severity. Urgent Security Alert: Cisco Zero-Day Vulnerability Under Active ExploitationĬisco has identified a grave zero-day vulnerability (CVE-2023-20198) within the Web User Interface of their IOS XE software, posing a significant threat to exposed Internet and untrusted networks. #Cybersecurity #Intel #CPUVulnerability #TechUpdate ![]() Intel also states that this issue is unlikely to be encountered by non-malicious real-world software, as malicious exploitation requires the execution of arbitrary code. While Intel has released updated microcode for all affected processors as part of its November 2023 updates, they note that there is no evidence of any active attacks using this vulnerability. This could also lead to information disclosure or privilege escalation. An exploit on one guest machine can cause the host machine to crash, resulting in a Denial of Service for other guest machines on the same host. The vulnerability is especially significant in multi-tenant virtualized environments. This flaw, affecting desktop, mobile, and server CPUs, could potentially lead to privilege escalation, information disclosure, and denial of service through local access. Intel has recently addressed a critical vulnerability in its CPUs, codenamed "Reptar" (CVE-2023-23583, CVSS score: 8.8).
