Description

The TRENDnet TI-PG1284i switch(hw v2.0R) prior to version 2.0.2.S0 suffers from an integer underflow vulnerability. This vulnerability exists in its lldp related component. Due to lack of proper validation on length field of ChassisID TLV, by sending a crafted lldp packet to the device, integer underflow would occur and the negative number will be passed to memcpy() later, which may cause buffer overflow or invalid memory access.

Affected configurations

• trendnet ti-pg1284i firmware (< 2.0.2.s0) • trendnet ti-g102i firmware • trendnet ti-g160i firmware • trendnet ti-g642i firmware • trendnet ti-pg102i firmware • trendnet ti-pg541i firmware • trendnet ti-rp262i firmware • trendnet teg-30102ws firmware • trendnet tpe-30102ws firmware
