Official description

A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The length of the URL component contained in pre-authenticated HTTP messages is not properly validated before appending additional data to it, resulting in an out-of-bounds write condition in memory. This could allow an unauthenticated remote attacker to crash the affected device, causing a reboot and resulting in a denial-of-service condition.
