What it is

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.
