D-Link DSL-2760U Gateway Cross-Site Scripting Vulnerability

Multiple cross-site scripting (XSS) vulnerabilities in D-Link DSL-2760U Gateway (Rev. E1) allow remote authenticated users to inject arbitrary web script or HTML via the (1) ntpServer1 parameter to sntpcfg.cgi, username parameter to (2) ddnsmngr.cmd or (3) todmngr.tod, (4) TodUrlAdd parameter to urlfilter.cmd, (5) appName parameter to scprttrg.cmd, (6) fltName in an add action or (7) rmLst parameter in a remove action to scoutflt.cmd, (8) groupName parameter to portmapcfg.cmd, (9) snmpRoCommunity parameter to snmpconfig.cgi, (10) fltName parameter to scinflt.cmd, (11) PolicyName in an add action or (12) rmLst parameter in a remove action to prmngr.cmd, (13) ippName parameter to ippcfg.cmd, (14) smbNetBiosName or (15) smbDirName parameter to samba.cgi, or (16) wlSsid parameter to wlcfg.wl.

IACS Radar priority score

72/ 100

Based on CVSS 5.4, EPSS 50.8%, industrial relevance 50/100; raised due to confirmed active exploitation (KEV).

Combines CVSS, EPSS, KEV status, industrial relevance and exposure relevance — a complement to, not a replacement for, the individual scores below and above.

Conditions for exploitation

•Network access to the affected device or segment is required.
•Limited user privileges are required.
•User interaction (for example opening a file) is required.

Operational impact & energy relevance

Limited impact on availability; the risk lies mainly with confidentiality or integrity of process data.

No strong energy-sector-specific signals recognised; general OT/ICS relevance.

Recommended defensive measures

•Apply the latest firmware or software update and validate its integrity.
•Restrict network access to the affected device to a dedicated OT management segment.
•Implement network segmentation in line with zones and conduits (IEC 62443-3-2).
•Monitor for abnormal protocol traffic using an OT-aware detection system.

Industrial relevance score

50/ 100

• Product description matches the category "protocol-gateway", a typical OT/ICS component type.
• Included in the CISA KEV catalogue: confirmed evidence of actual exploitation.

Classification is provisional; manual verification by an OT security analyst is recommended.

Classified by IACS Radar-analysepijplijn (geautomatiseerd) on 7 November 2026.
