Critical SSRF Vulnerability Affects SonicWall SMA1000 Series Remote Access Appliances

SonicWall has disclosed four vulnerabilities in its SMA1000 series remote access products, with one rated critical. The most severe issue, CVE-2026-102255, is a server-side request forgery flaw in the WorkPlace interface that allows unauthenticated attackers to abuse the appliance as a forward proxy and reach internal functions. The vulnerability received the maximum CVSSv3.0 base score of 10.0. Two additional flaws, CVE-2026-102256 and CVE-2026-102257, enable authenticated OS command injection and unauthenticated path traversal via crafted archives, respectively. No exploitation has been observed in the wild at the time of disclosure. SonicWall has released updates to address all issues.

CISA Adds Seven Actively Exploited Vulnerabilities to KEV Catalog, Including SonicWall and LiteLLM Flaws Targeting AI Infrastructure

CISA has added seven vulnerabilities confirmed to be exploited in the wild to its Known Exploited Vulnerabilities catalog, with two carrying CVSS scores of 10.0. The list includes critical issues in SonicWall SMA 1000 devices, JFrog Artifactory, Kestra workflow engine, and LiteLLM AI gateway components. Attackers are now systematically targeting AI infrastructure to steal large language model API keys and configuration data from databases such as LiteLLM_ProxyModelTable. Qilin ransomware operators have already chained LiteLLM flaws for remote code execution and data theft. CISA has set a 48-hour remediation deadline for federal agencies, underscoring the urgency for all organizations running these components.

SonicWall SMA 1000 Series Affected by Critical Vulnerabilities with Evidence of Exploitation

SonicWall has disclosed two serious vulnerabilities in its SMA 1000 series remote access appliances. The issues, tracked as CVE-2026-83548 and CVE-2026-83549, affect the SMA 6210, SMA 7210, and SMA 8200v models. CVE-2026-83548 is a server-side request forgery flaw in the WorkPlace interface that permits unauthenticated remote access to otherwise restricted functions. CVE-2026-83549 is an OS command injection vulnerability in the Appliance Management Console that can lead to remote command execution after authentication under certain conditions. Both vulnerabilities received high CVSS scores, with one reaching the maximum of 10.0. The vendor published the advisory on September 1, 2026, and confirmed cases where the flaws appear to have been exploited in the wild.

SonicWall Patches Critical Path Traversal and Update Flaws in NetExtender for Linux

SonicWall has released fixes for two high-severity vulnerabilities in its NetExtender client for Linux that could allow remote attackers to write arbitrary files with root privileges and manipulate the automatic update process. The flaws impact versions 10.3.5 and earlier, while the Windows version remains unaffected. CVE-2026-66152 carries a CVSS score of 8.8 and stems from improper handling of tar archives containing OPSWAT data, enabling path traversal that lets attackers escape the intended extraction directory. CVE-2026-66153 scores 7.0 and arises from inadequate symlink and temporary file handling in the NEService update mechanism. Both issues require user interaction to exploit, and no in-the-wild attacks have been observed so far. Administrators are urged to upgrade immediately to version 10.3.6 or later, as no workarounds exist.

SonicWall Global Management System Hit by Critical RCE and Path Traversal Vulnerabilities

SonicWall has disclosed six vulnerabilities in its SonicWall Global Management System (GMS) management product, with the highest-severity issues rated Critical. The most severe flaw, CVE-2026-66147, resides in the Dispatcher Service and allows unauthenticated remote code execution through crafted requests that inject commands. A second critical issue, CVE-2026-66145, stems from improper handling of zip archive extraction and enables path traversal attacks that can read sensitive data or write arbitrary files without authentication. Both vulnerabilities received CVSSv3 base scores above 9.0. The flaws affect both the virtual appliance and Windows versions of GMS. SonicWall released an advisory on August 11 urging immediate application of the available updates.

Weekly Roundup Highlights Critical Vulnerabilities in Zoom, nginx, SonicWall, and Microsoft Products

Security NEXT published its weekly ranking of the most-read articles for the period of July 12 to July 18, 2026. The top story covered a serious vulnerability in the Windows version of Zoom that has already been fixed in the latest release. Other high-ranking items included a cyber attack that disrupted operations at Nichirei and affected frozen food shipments, as well as Microsoft’s monthly security update addressing more than 500 vulnerabilities including zero-days. Additional widely read reports detailed multiple flaws in nginx, a zero-day issue affecting SonicWall SMA1000 series appliances, and a data exposure investigation involving a TV Asahi subsidiary. The list also featured advisories on GNU Wget SSRF flaws, privilege escalation bugs in Microsoft Defender, and 15 security fixes for Chrome including two rated critical.

SonicWall Issues Emergency Hotfixes After Detecting Active Exploitation of Two Zero-Day Vulnerabilities in SMA1000 Appliances

SonicWall has confirmed active exploitation of two zero-day vulnerabilities in its SMA1000 series appliances, prompting the immediate release of hotfixes and a strict compliance deadline for U.S. federal agencies. The first flaw, CVE-2026-15409, carries a critical CVSS score of 10.0 and allows unauthenticated server-side request forgery (SSRF) through the Appliance Work Place interface, enabling attackers to force the device to make unauthorized requests to internal services. The second vulnerability, CVE-2026-15410, rated CVSS 7.2, permits authenticated code injection via the Appliance Management Console, allowing administrators to execute operating system commands. Affected models include SMA6210, SMA7210, and SMA8200v running specific vulnerable platform versions such as 12.4.3-03245 through 12.5.0-02800. CISA has added both CVEs to its Known Exploited Vulnerabilities catalog, requiring federal agencies to patch or decommission impacted systems by July 17, 2026. Indicators of compromise and recommended response actions, including log analysis and potential appliance reimaging, have been published to help organizations detect and mitigate potential intrusions.

Cybercriminals Actively Exploiting Critical Zero-Day Vulnerabilities in SonicWall SMA1000 Appliances

Cybercriminals are actively exploiting a critical zero-day vulnerability in SonicWall SMA1000 appliances used for corporate remote access. The attack chain combines two flaws that together enable unauthenticated access to internal services and local privilege escalation, ultimately allowing remote code execution with maximum privileges on affected devices. The most severe issue, CVE-2026-15409, carries a maximum CVSS score of 10.0 and permits attackers to reach internal appliance services without authentication, while CVE-2026-15410 facilitates local privilege escalation. Impacted models include the SMA1000 Series 6210, 7210, and 8200v running firmware versions 12.4.3-03434 and 12.5.0-02800. SonicWall has confirmed that its SSL VPN firewalls and the SMA 100 product line remain unaffected. Compromised appliances have already been observed serving as stealthy entry points into corporate networks, where attackers harvested credentials, session data, and multi-factor authentication seeds before pivoting into Active Directory environments. Administrators are urged to apply the emergency patches that upgrade devices to firmware versions 12.4.3-03453, 12.5.0-02835, or later.
