CVE-2011-4501
HighSummary
The UPnP IGD implementation in Edimax EdiLinux on various router models allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface. This affects routers with specific firmware versions.
Risk Assessment
Attackers can exploit this vulnerability to take control of network traffic, potentially leading to unauthorized access to the organization's internal resources.
Recommendation
It is recommended to update the router firmware to the latest versions that mitigate this vulnerability and to disable UPnP if it is not necessary.
