Title
Stored Cross-Site Scripting (XSS) via Configuration File Import on TP-Link's TL-SG108PE
Summary
A stored cross-site scripting (XSS) vulnerability has been identified in the web management interface of TP-Link's TL-SG108PE v5 switch due to improper sanitation of the SYSNAM configuration parameter during configuration file import. An attacker with administrator access can inject malicious script into the device configuration, which may be stored and executed in the administrator’s browser when the affected interface is viewed.     Successful exploitation may allow session cookie theft, unauthorized configuration changes, or access to sensitive information exposed through the management interface.
