Full vulnerability record from the local CVENow database.
Description
A vulnerability has been identified in blueplanet 100 NX3 M8 (All versions), blueplanet 100 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 105 TL3 (All versions < V3.92), blueplanet 105 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 110 TL3 (All versions < V3.92), blueplanet 125 NX3 M10 (All versions), blueplanet 125 TL3 (All versions < V3.92), blueplanet 125 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 137 TL3 (All versions < V3.92), blueplanet 150 TL3 (All versions < V3.92), blueplanet 150 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 155 TL3 (All versions < V3.92), blueplanet 155 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 165 TL3 (All versions < V3.92), blueplanet 165 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 3.0 TL3-60.0 TL3 (All versions), blueplanet 87.0 TL3 (All versions < V3.92), blueplanet 87.0 TL3 GEN2 (All versions < V6.1.4.9), blueplanet 92.0 TL3 (All versions < V3.92), blueplanet 92.0 TL3 GEN2 (All versions < V6.1.4.9), blueplanet gridsave 110 TL3-S (All versions < V3.91), blueplanet gridsave 137 TL3-S (All versions < V3.91), blueplanet gridsave 92.0 TL3-S (All versions < V3.91). A CRC16-based algorithm for generating Technical Service credentials could allow an attacker to derive the credentials from the devices serial number and misuse them to gain unauthorized access.
