| CVE ID | CVSS Score | Severity | Description |
|---|---|---|---|
| CVE-2026-63350 | 9.6 | critical |
CVE-2026-63350. Affected devices do not properly restrict executable content contained in imported trace files.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
|
| CVE-2026-63356 | 6.1 | medium |
CVE-2026-63356. Affected devices do not properly sanitize calculated signal names contained in imported CSV trace files before including them in error messages on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Attacker-controlled JavaScript could be executed in the user’s browser session when the resulting error message is displayed.
|
| CVE-2026-63352 | 6.1 | medium |
CVE-2026-63352. Affected devices do not properly sanitize calculated signal data contained in imported CSV trace files before rendering it on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
|
| CVE-2026-63351 | 6.1 | medium |
CVE-2026-63351. Affected devices do not properly validate and sanitize visual properties of calculated signals contained in imported CSV trace files before rendering them on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
|
| CVE-2026-63357 | 6.1 | medium |
CVE-2026-63357. Affected devices do not properly sanitize calculated signal data contained in imported calculated signal files before rendering it on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
|
| CVE-2026-63353 | 9.6 | critical |
CVE-2026-63353. Affected devices do not properly sanitize comment fields contained in imported trace files before rendering them on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
|
| CVE-2026-63355 | 6.1 | medium |
CVE-2026-63355. Affected devices do not properly sanitize signal names contained in imported CSV trace files before rendering them in selection menus on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Attacker-controlled JavaScript could be executed in the user’s browser session when the user subsequently interacts with an affected selection menu.
|
| CVE-2026-63354 | 9.6 | critical |
CVE-2026-63354. Affected devices do not properly validate and sanitize visual marker data contained in imported CSV trace files before rendering it on the Trace page.
This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.
