Description

An issue was discovered on Swisscom Internet Box 2, Internet Box Standard, Internet Box Plus prior to 10.04.38, Internet Box 3 prior to 11.01.20, and Internet Box light prior to 08.06.06. Given the (user-configurable) credentials for the local Web interface or physical access to a device's plus or reset button, an attacker can create a user with elevated privileges on the Sysbus-API. This can then be used to modify local or remote SSH access, thus allowing a login session as the superuser.

Affected configurations

• swisscom internet-box 2 firmware (< 10.04.38) • swisscom internet-box standard firmware (< 10.04.38) • swisscom internet-box plus firmware (< 10.04.38) • swisscom internet-box 3 firmware (< 11.01.20) • swisscom internet-box light firmware (< 08.06.06)
