TITLE

Multiple I-O DATA network camera products vulnerable to buffer overflow

Trust: 0.8

sources: JVNDB: JVNDB-2016-000235

DESCRIPTION

Buffer overflow in I-O DATA DEVICE TS-WRLP firmware version 1.01.02 and earlier and TS-WRLA firmware version 1.01.02 and earlier allows an attacker with administrator rights to cause a denial-of-service (DoS) or execute arbitrary code via unspecified vectors. Multiple network camera products provided by I-O DATA DEVICE, INC. contain buffer overflow vulnerability. Taizoh Tsukamoto of Mitsui Bussan Secure Directions, Inc. reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.Arbitrary code may be executed or a denial-of-service (DoS) condition may be caused. Attackers may leverage these issues to execute arbitrary code and commands in the context of the affected device. Failed exploits may result in denial-of-service conditions. The following products are affected : TS-WRLP firmware version 1.01.02 and prior. TS-WRLA firmware version 1.01.02 and prior
