CVE-2018-16596
7.5 · HIGHOverview
CVE-2018-16596 is a high-severity vulnerability affecting swisscom internet-box_standard_firmware. It was published on December 17, 2018 and has a CVSS 3.0 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.0 base score of 7.5, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
A stack-based buffer overflow in the LAN UPnP service running on UDP port 1900 of Swisscom Internet-Box (2, Standard, and Plus) prior to v09.04.00 and Internet-Box light prior to v08.05.02 allows remote code execution. No authentication is required to exploit this vulnerability. Sending a simple UDP packet to port 1900 allows an attacker to execute code on a remote device. However, this is only possible if the attacker is inside the LAN. Because of ASLR, the success rate is not 100% and leads instead to a DoS of the UPnP service. The remaining functionality of the Internet Box is not affected. A reboot of the Internet Box is necessary to attempt the exploit again.
Remediation
Check the references section for vendor advisories and patches from swisscom. Update internet-box_standard_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
