Vulnerabilities in this advisory

• CVE-2025-40891 — CVE-2025-40891 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Time Machine Snapshot Diff functionality due to improper validation of network traffic data. An unauthenticated attacker can send specially crafted network packets at two different times to inject HTML tags into asset attributes across two snapshots. Exploitation requires a victim to use the Time Machine Snapshot Diff feature on those specific snapshots and perform specific GUI actions, at which point the injected HTML renders in their browser, enabling phishing and open redirect attacks. Full XSS exploitation is prevented by input validation and Content Security Policy. Attack complexity is high due to multiple required conditions.

• CVE-2025-40892 — CVE-2025-40892 · CWE-79

  A Stored Cross-Site Scripting vulnerability was discovered in the Reports functionality due to improper validation of an input parameter. An authenticated user with report privileges can define a malicious report containing a JavaScript payload, or a victim can be socially engineered to import a malicious report template. When the victim views or imports the report, the XSS executes in their browser context, allowing the attacker to perform unauthorized actions as the victim, such as modify application data, disrupt application availability, and access limited sensitive information.

• CVE-2025-40893 — CVE-2025-40893 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Asset List functionality due to improper validation of network traffic data. An unauthenticated attacker can send specially crafted network packets to inject HTML tags into asset attributes. When a victim views the affected assets in the Asset List (and similar functions), the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40894 — CVE-2025-40894 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Alerted Nodes Dashboard functionality due to improper validation on an input parameter. A malicious authenticated user with the required privileges could edit a node label to inject HTML tags. If the system is configured to use the Alerted Nodes Dashboard, and alerts are reported for the affected node, then the injected HTML may render in the browser of a victim user interacting with it, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40897 — CVE-2025-40897 · CWE-863

  An access control vulnerability was discovered in the Threat Intelligence functionality due to a specific access restriction not being properly enforced for users with view-only privileges. An authenticated user with view-only privileges for the Threat Intelligence functionality can perform administrative actions on it, altering the rules configuration, and/or affecting their availability.

• CVE-2025-40898 — CVE-2025-40898 · CWE-22

  A path traversal vulnerability was discovered in the Import Arc data archive functionality due to insufficient validation of the input file. An authenticated user with limited privileges, by uploading a specifically-crafted Arc data archive, can potentially write arbitrary files in arbitrary paths, altering the device configuration and/or affecting its availability.

• CVE-2025-40899 — CVE-2025-40899 · CWE-79

  A Stored Cross-Site Scripting vulnerability was discovered in the Assets and Nodes functionality due to improper validation of an input parameter. An authenticated user with custom fields privileges can define a malicious custom field containing a JavaScript payload. When the victim views the Assets or Nodes pages, the XSS executes in their browser context, allowing the attacker to perform unauthorized actions as the victim, such as modify application data, disrupt application availability, and access limited sensitive information.

• CVE-2025-40900 — CVE-2025-40900 · CWE-1336

  An Angular template injection vulnerability was discovered in the Reports functionality due to improper validation of an input parameter. An authenticated user with report privileges can define a malicious report containing an Angular template payload, or a victim can be socially engineered to import a malicious report template. When the victim views or imports the report, the Angular template executes in their browser context, allowing the attacker to modify application data, or disrupt application availability. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40901 — CVE-2025-40901 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Credentials Manager functionality due to improper validation of an input parameter. An authenticated user with administrative privileges can define a malicious identity containing HTML tags. When a victim attempts to delete the affected identity, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40902 — CVE-2025-40902 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Users functionality due to improper validation of an input parameter. An authenticated user with administrative privileges can create a malicious user whose username contains HTML tags. When a victim attempts to delete a group containing the affected user, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40903 — CVE-2025-40903 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Schedule Restore Archive functionality due to improper validation of an input parameter. An authenticated user with administrative privileges can define a malicious restore schedule containing HTML tags. When a victim views the affected schedule, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

• CVE-2025-40904 — CVE-2025-40904 · CWE-79

  A Stored HTML Injection vulnerability was discovered in the Smart Polling functionality due to improper validation of an input parameter. An authenticated user with limited privileges can push malicious remote strategies containing HTML tags through the sync. When a victim views the affected remote strategy in the Smart Polling functionality, the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.
