Summary

Vigor165/166 4.2.7 and earlier; Vigor2620/LTE200 3.9.8.9 and earlier; Vigor2860/2925 3.9.8 and earlier; Vigor2862/2926 3.9.9.5 and earlier; Vigor2133/2762/2832 3.9.9 and earlier; Vigor2135/2765/2766 4.4.5. and earlier; Vigor2865/2866/2927 4.4.5.3 and earlier; Vigor2962 4.3.2.8 and earlier; Vigor3912 4.3.6.1 and earlier; Vigor3910 4.4.3.1 and earlier a stack-based buffer overflow vulnerability has been identified in the URL parsing functionality of the TR069 STUN server. This flaw occurs due to insufficient bounds checking on the amount of URL parameters, allowing an attacker to exploit the overflow by sending a maliciously crafted request. Consequently, a remote attacker can execute arbitrary code with elevated privileges.
