Arch Linux Security Advisory ASA-202012-16 ========================================== Severity: Medium Date : 2020-12-09 CVE-ID : CVE-2020-12695 Package : hostapd Type : proxy injection Remote : Yes Link : https://security.archlinux.org/AVG-1322 Summary ======= The package hostapd before version 2.9-4 is vulnerable to proxy injection. Resolution ========== Upgrade to 2.9-4. # pacman -Syu "hostapd>=2.9-4" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue. This issue could allow a device connected to the local network (i.e., a device that has been authorized to transmit packets in the network in which the AP is located) to trigger the AP to initiate a HTTP (TCP/IP) connection to an arbitrary URL, including connections to servers in external networks. Impact ====== An attacker on the local network might be able to force the AP to initiate a HTTP (TCP/IP) connection to an arbitrary URL, including connections to servers in external networks.
