CVE-2016-8562
In short
A vulnerability in SIMATIC CP 1543-1 networking devices allows attackers to modify SNMP settings that should be read-only, potentially disrupting network operations or causing the device to stop functioning.
Technical detail
Unauthenticated SNMP write access on UDP port 161 permits modification of read-only variables in affected SIMATIC CP 1543-1 and SIPLUS NET CP 1543-1 devices. Exploitation requires network access to the device and special conditions; successful writes can degrade availability or trigger denial-of-service.
Summary generated and translated by AI from the official description.
A vulnerability has been identified in SIMATIC CP 1543-1 (All versions < V2.0.28), SIPLUS NET CP 1543-1 (All versions < V2.0.28). Under special conditions it was possible to write SNMP variables on port 161/udp which should be read-only and should only be configured with TIA-Portal. A write to these variables could reduce the availability or cause a denial-of-service.
