D-Link - DSL-2760U · Listed in the CISA KEV since 2022-03-25. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2013-5223
MediumCVSS 5.4KEVSummary
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 various parameters in CGI files, such as ntpServer1, username, TodUrlAdd, appName, fltName, rmLst, groupName, snmpRoCommunity, PolicyName, ippName, smbNetBiosName, smbDirName, wlSsid.
Risk Assessment
An authenticated attacker can execute malicious script in the administrator's browser, potentially leading to session hijacking or device configuration changes. This may result in full compromise of the network gateway.
Recommendation
Update the D-Link DSL-2760U gateway firmware to the latest version if a fix is available. It is also recommended to restrict access to the administrative interface and implement XSS protection.
