Cisco SD-WAN Zero-Day CVE-2026-20127 Exploited Since 2023 for Admin Access

Cisco SD-WAN Zero-Day CVE-2026-20127 Exploited Since 2023 for Admin Access

Feb 26, 2026 Vulnerability / Network Security
A newly disclosed maximum-severity security flaw in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Catalyst SD-WAN Manager (formerly vManage) has come under active exploitation in the wild as part of malicious activity that dates back to 2023. The vulnerability, tracked as CVE-2026-20127 (CVSS score: 10.0), allows an unauthenticated remote attacker to bypass authentication and obtain administrative privileges on the affected system by sending a crafted request to an affected system. Successful exploitation of the flaw could allow the adversary to obtain elevated privileges on the system as an internal, high-privileged, non-root user account. "This vulnerability exists because the peering authentication mechanism in an affected system is not working properly," Cisco said in an advisory, adding the threat actor could leverage the non-root user account to access NETCONF and manipulate network configuration for the SD-WAN fabric.  The shortcoming affects the follo...
Claude Code Flaws Allow Remote Code Execution and API Key Exfiltration

Claude Code Flaws Allow Remote Code Execution and API Key Exfiltration

Feb 25, 2026 Artificial Intelligence / Vulnerability
Cybersecurity researchers have disclosed multiple security vulnerabilities in Anthropic's Claude Code, an artificial intelligence (AI)-powered coding assistant, that could result in remote code execution and theft of API credentials. "The vulnerabilities exploit various configuration mechanisms, including Hooks, Model Context Protocol (MCP) servers, and environment variables – executing arbitrary shell commands and exfiltrating Anthropic API keys when users clone and open untrusted repositories," Check Point researchers Aviv Donenfeld and Oded Vanunu said in a report shared with The Hacker News. The identified shortcomings fall under three broad categories - No CVE (CVSS score: 8.7) - A code injection vulnerability stemming from a user consent bypass when starting Claude Code in a new directory that could result in arbitrary code execution without additional confirmation via untrusted project hooks defined in .claude/settings.json. (Fixed in version 1.0.87 in Sep...

SolarWinds Patches 4 Critical Serv-U 15.5 Flaws Allowing Root Code Execution

Feb 25, 2026 Vulnerability / Windows Security
SolarWinds has released updates to address four critical security flaws in its Serv-U file transfer software that, if successfully exploited, could result in remote code execution. The vulnerabilities, all rated 9.1 on the CVSS scoring system, are listed below - CVE-2025-40538 - A broken access control vulnerability that allows an attacker to create a system admin user and execute arbitrary code as root via domain admin or group admin privileges. CVE-2025-40539 - A type confusion vulnerability that allows an attacker to execute arbitrary native code as root. CVE-2025-40540 - A type confusion vulnerability that allows an attacker to execute arbitrary native code as root. CVE-2025-40541 - An insecure direct object reference (IDOR) vulnerability that allows an attacker to execute native code as root. SolarWinds noted that the vulnerabilities require administrative privileges for successful exploitation. It also said that they carry a medium security risk on Windows deployme...

CISA Confirms Active Exploitation of FileZen CVE-2026-25108 Vulnerability

CISA Confirms Active Exploitation of FileZen CVE-2026-25108 Vulnerability

Feb 25, 2026 Vulnerability / Software Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added a recently disclosed vulnerability in FileZen to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-25108 (CVSS v4 score: 8.7), is a case of operating system (OS) command injection that could allow an authenticated user to execute arbitrary commands via specially crafted HTTP requests. "Soliton Systems K.K FileZen contains an OS command injection vulnerability when a user logs-in to the affected product and sends a specially crafted HTTP request," CISA said. According to the Japan Vulnerability Notes (JVN), the vulnerability affects the following versions of the file transfer product - Versions 4.2.1 to 4.2.8 Versions 5.0.0 to 5.0.10 Soliton noted in its advisory that successful exploitation of the issue is only possible when FileZen Antivirus Check Option is enabled, adding it has "received at le...
UnsolicitedBooker Targets Central Asian Telecoms With LuciDoor and MarsSnake Backdoors

UnsolicitedBooker Targets Central Asian Telecoms With LuciDoor and MarsSnake Backdoors

Feb 24, 2026 Malware / Vulnerability
The threat activity cluster known as UnsolicitedBooker has been observed targeting telecommunications companies in Kyrgyzstan and Tajikistan, marking a shift from prior attacks aimed at Saudi Arabian entities. The attacks involve the deployment of two distinct backdoors codenamed LuciDoor and MarsSnake, according to a report published by Positive Technologies last week. "The group used several unique and rare instruments of Chinese origin," researchers Alexander Badaev and Maxim Shamanov said . UnsolicitedBooker was first documented by ESET in May 2025, attributing the China-aligned threat actor to a cyber attack targeting an unnamed international organization in Saudi Arabia with a backdoor dubbed MarsSnake. The group is assessed to be active since at least March 2023 and has a history of targeting organizations in Asia, Africa, and the Middle East. Further analysis of the threat actor has uncovered tactical overlaps with two other clusters, including Space Pirates an...
