6.1CVE-2026-63357siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.25%
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.
6.1CVE-2026-63356siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.25%
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.
6.1CVE-2026-63355siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.25%
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.
9.6CVE-2026-63354siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.45%
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.
9.6CVE-2026-63353siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.41%
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.
6.1CVE-2026-63352siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.24%
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.
6.1CVE-2026-63351siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.24%
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.
9.6CVE-2026-63350siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.41%
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.
9.6CVE-2025-40943siemenssimatic drive controller cpu 1504d tf+102
EPSS score
0.48%
Affected devices do not properly sanitize contents of trace files. This could allow an attacker to inject code through social engineering an authorized user, who has the function right "Read diagnostics", to import a specially crafted trace file. The malicious trace file is insufficiently sanitized and malicious code could be executed in the clients browser session and trigger PLC operations via the webserver that the legitimate user is authorized to perform.
9.3CVE-2026-25787siemenssimatic drive controller cpu 1504d tf+101
EPSS score
0.54%
Affected devices do not properly validate and sanitize Technology Object (TO) name rendered on the "Motion Control Diagnostics" page of the web interface. This could allow an authenticated attacker who is authorized to download a TIA project into the product, to inject malicious scripts into the page. If a benign user with appropriate rights accesses the "Motion Control Diagnostics" parameters page, the malicious code would be executed in the scope of their web session.
7.2CVE-2026-25789siemenssimatic drive controller cpu 1504d tf+101
EPSS score
0.47%
Affected devices do not properly validate and sanitize filenames on the Firmware Update page. This could allow a remote attacker to social engineer the user into selecting the modified firmware file to be uploaded. This would result in malitcious JavaScript execution in the context of the authenticated user's session without requiring the file to be uploaded, potentially leading to session hijacking or credential theft.
9.3CVE-2026-25786siemenssimatic drive controller cpu 1504d tf+101
EPSS score
0.54%
Affected devices do not properly validate and sanitize PLC/station name rendered on the "communication" parameters page of the web interface. This could allow an authenticated attacker who is authorized to download a TIA project into the product, to inject malicious scripts into the page. If a benign user with appropriate rights accesses the "communication" parameters page, the malicious code would be executed in the scope of their web session.
