An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition or leak the memory past the allocated structure.Ī vulnerability has been identified in Nucleus 4 (All versions < V4.1.0), Nucleus NET (All versions), Nucleus RTOS (versions including affected DNS modules), Nucleus ReadyStart (All versions < V2017.02.3), Nucleus Source Code (versions including affected DNS modules), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), VSTAR (versions including affected DNS modules).

The parsing of malformed responses could result in a read past the end of an allocated structure. The DNS response parsing functionality does not properly validate various length and counts of the records.

An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition.Ī vulnerability has been identified in Nucleus 4 (All versions < V4.1.0), Nucleus NET (All versions), Nucleus RTOS (versions including affected DNS modules), Nucleus ReadyStart (All versions < V2017.02.3), Nucleus Source Code (versions including affected DNS modules), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), VSTAR (versions including affected DNS modules). The parsing of malformed responses could result in a read access past the end of an allocated structure. The DNS domain name record decompression functionality does not properly validate the pointer offset values. The function that processes IPv6 headers does not check the lengths of extension header options, allowing attackers to put this function into an infinite loop with crafted length values.ħ Capital Vstar, Nucleus 4, Nucleus Net and 4 moreĪ vulnerability has been identified in Nucleus 4 (All versions < V4.1.0), Nucleus NET (All versions), Nucleus RTOS (versions including affected DNS modules), Nucleus ReadyStart (All versions < V2017.02.3), Nucleus Source Code (versions including affected DNS modules), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), VSTAR (versions including affected DNS modules).

An unauthenticated remote attacker could exploit this issue to access sensitive information for subsequent attacks.Ĥ Capital Vstar, Nucleus Net, Nucleus Readystart and 1 moreĪ vulnerability has been identified in Nucleus 4 (All versions < V4.1.0), Nucleus NET (All versions), Nucleus ReadyStart (All versions), Nucleus Source Code (versions including affected IPv6 stack), VSTAR (versions including affected IPv6 stack). The affected application contains a path traversal vulnerability that could allow to read arbitrary files on the server that are outside the application’s web document directory.
