QNAP addresses multiple vulnerabilities in its product line affecting Surveillance Station and Photo Station applications using a vulnerability management tool. These vulnerable software applications are powered by Network Attached Storage (NAS), a storage management technology powering file sharing, virtualization, and surveillance applications.

Surveillance Station is a network surveillance Video Management System (VMS) application that helps users manage and monitor IP cameras. Photo Station software application is used to upload images to NAS devices later used to view remotely. However, the end adversary target is always the NAS device powering both the vulnerable software applications.  A patch management solution can effectively protect your NAS device from potential vulnerabilities exploited through maliciousvideo animation files.

Surveillance Station Critical Remote Code Execution (RCE) Vulnerability | CVE-2020-2501

A stack-based buffer overflow issue causing remote code execution vulnerability in QNAP NAS devices running the Surveillance Station application. QNAP’s security adversary says

“If exploited, this vulnerability allows attackers to execute arbitrary code.”

On successful exploitation, attackers can persist inside the network and may take control of the running security service and anti-malware programs. QNAP has already fixed the vulnerability, and patches released for the following versions.

“Surveillance Station 5.1.5.4.3 (and later) for ARM CPU NAS (64bit OS) and x86 CPU NAS (64bit OS) Surveillance Station 5.1.5.3.3 (and later) for ARM CPU NAS (32bit OS) and x86 CPU NAS (32bit OS)”

Photo Station Cross-Site Scripting (XSS) Vulnerability | CVE-2020-2502

An XSS vulnerability exists in QNAP NAS running earlier versions of the Photo Station software application. QNAP’s security adversary says

“If exploited, this vulnerability allows remote attackers to inject malicious code.”

On successful exploitation, attackers can steal sensitive information by tricking the victim’s vulnerable application by malicious programs. The patch is available, and the vendors fixed the issue in Photo Station 6.0.11 and later.

Updating Vulnerable QNAP Applications

This workaround referred to update both the Surveillance Station and Photo Station to the latest versions.

“Note: Users require admin privilege in NAS devices to update the software applications by following below steps Note: Surveillance Station or Photo Station should be placed instead of Application Name. Note: The Update button is not available if your version is already up to date.”

  1. Log on to QTS as administrator.
  2. Open the App Center and search for the Application Name.
  3. Click Update (A confirmation message appears)
  4. Click OK

Now your application successfully updated.

Silent Lynx Hits CIS Governments With WinRAR Flaw

Silent Lynx (UAT-6275 / TAG-193) is a cyber-espionage actor targeting government organizations across the Commonwealth of Independent States. From June 2025 through August 2026, the group used four infection chains, including macro-enabled documents, PS2EXE downloaders, LNK-based PowerShell loaders, and WinRAR archives that exploit CVE-2025-8088, to deploy custom reverse shells such as FoalShell, Chvost, Laplas, and PickleShell. Activity spans nine countries and focuses on diplomacy, economic development, environmental management, water resources, and energy. This article summarizes the campaign’s delivery methods, infrastructure exposure, indicators of compromise, and practical mitigations for defenders.

Drupal Fixes Critical Field UI Flaw Linked to Remote Code Execution

A critical vulnerability in Drupal core's Field UI module could allow attackers to execute arbitrary code on vulnerable websites through exposed contributed modules or custom code. Tracked as CVE-2026-108097, the flaw stems from improper validation of PHP callbacks during table rendering. At least one known exploitation path does not require authentication, potentially putting affected websites at risk of server compromise.
