Uncontrolled resource consumption vulnerability in MELSEC iQ-R Series CPU Modules (R00/01/02CPU Firmware versions from '05' to '19' and R04/08/16/32/120(EN)CPU Firmware versions from '35' to '51') allows a remote attacker to cause an error in a CPU unit via a specially crafted HTTP packet, which may lead to a denial-of-service (DoS) condition in execution of the program and its communication.

Uncontrolled resource consumption vulnerability in Ethernet Port on MELSEC iQ-R, Q and L series CPU modules (R 00/01/02 CPU firmware versions '20' and earlier, R 04/08/16/32/120 (EN) CPU firmware versions '52' and earlier, R 08/16/32/120 SFCPU firmware versions '22' and earlier, R 08/16/32/120 PCPU all versions, R 08/16/32/120 PSFCPU all versions, R 16/32/64 MTCPU all versions, Q03 UDECPU, Q 04/06/10/13/20/26/50/100 UDEHCPU serial number '22081' and earlier , Q 03/04/06/13/26 UDVCPU serial number '22031' and earlier, Q 04/06/13/26 UDPVCPU serial number '22031' and earlier, Q 172/173 DCPU all versions, Q 172/173 DSCPU all versions, Q 170 MCPU all versions, Q 170 MSCPU all versions, L 02/06/26 CPU (-P) and L 26 CPU - (P) BT all versions) allows a remote unauthenticated attacker to stop the Ethernet communication functions of the products via a specially crafted packet, which may lead to a denial of service (DoS) condition .

Mitsubishi MELSEC iQ-R Series PLCs with firmware 33 allow attackers to halt the industrial process by sending an unauthenticated crafted packet over the network, because this denial of service attack consumes excessive CPU time. After halting, physical access to the PLC is required in order to restore production.

When MELSOFT transmission port (UDP/IP) of Mitsubishi Electric MELSEC iQ-R series (all versions), MELSEC iQ-F series (all versions), MELSEC Q series (all versions), MELSEC L series (all versions), and MELSEC F series (all versions) receives massive amount of data via unspecified vectors, resource consumption occurs and the port does not process the data properly. As a result, it may fall into a denial-of-service (DoS) condition. The vendor states this vulnerability only affects Ethernet communication functions.

On Swann DVR04B, DVR08B, DVR-16CIF, and DVR16B devices, raysharpdvr application has a vulnerable call to “system”, which allows remote attackers to execute arbitrary code via TCP port 9000.

An issue was discovered in OpenWrt libuci (aka Library for the Unified Configuration Interface) before 15.05.1 as used on Motorola CX2L MWR04L 1.01 and C1 MWR03 1.01 devices. /tmp/.uci/network locking is mishandled after reception of a long SetWanSettings command, leading to a device hang.

On the Motorola router CX2L MWR04L 1.01, there is a stack consumption (infinite recursion) issue in scopd via TCP port 8010 and UDP port 8080. It is caused by snprintf and inappropriate length handling.

The authorization implementation on Dahua DVR appliances accepts a hash string representing the current date for the role of a master password, which makes it easier for remote attackers to obtain administrative access and change the administrator password via requests involving (1) ActiveX, (2) a standalone client, or (3) unspecified other vectors, a different vulnerability than CVE-2013-3612.

Dahua DVR appliances have a small value for the maximum password length, which makes it easier for remote attackers to obtain access via a brute-force attack.

Dahua DVR appliances use a password-hash algorithm with a short hash length, which makes it easier for context-dependent attackers to discover cleartext passwords via a brute-force attack.
