CVE-2020-27009

https://notcve.org/view.php?id=CVE-2020-27009

A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus Source Code (Versions including affected DNS modules), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). The DNS domain name record decompression functionality does not properly validate the pointer offset values. The parsing of malformed responses could result in a write past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to execute code in the context of the current process or cause a denial-of-service condition. Se ha identificado una vulnerabilidad en Nucleus NET (Todas las versiones anteriores a V5.2), Nucleus Source Code (Versiones que incluyen los módulos DNS afectados). • https://cert-portal.siemens.com/productcert/pdf/ssa-180579.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-185699.pdf • CWE-787: Out-of-bounds Write CWE-823: Use of Out-of-range Pointer Offset •

The DNS domain name label parsing functionality does not properly validate the null-terminated name in DNS-responses. The parsing of malformed responses could result in a read past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition or leak the read memory. Se ha identificado una vulnerabilidad en Nucleus NET (Todas las versiones), Nucleus ReadyStart V3 (Todas las versiones anteriores a V2017.02.3), Nucleus ReadyStart V4 (Todas las versiones anteriores a V4.1.0), Nucleus Source Code (Versiones que incluyen los módulos DNS afectados), SIMOTICS CONNECT 400 (Todas las versiones anteriores a V0.5.0.0). • https://cert-portal.siemens.com/productcert/pdf/ssa-180579.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-669158.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-705111.pdf • CWE-125: Out-of-bounds Read CWE-170: Improper Null Termination •

A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus ReadyStart V3 (All versions < V2012.12), Nucleus Source Code (All versions), PLUSCONTROL 1st Gen (All versions), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). Initial Sequence Numbers (ISNs) for TCP connections are derived from an insufficiently random source. As a result, the ISN of current and future TCP connections could be predictable. An attacker could hijack existing sessions or spoof future ones. Se ha identificado una vulnerabilidad en Capital VSTAR (Todas las versiones), Nucleus NET (Todas las versiones anteriores a V5.2), Nucleus ReadyStart V3 (Todas las versiones anteriores a V2012.12), Nucleus Source Code (Todas las versiones), PLUSCONTROL 1st Gen (Todas las versiones). • https://cert-portal.siemens.com/productcert/pdf/ssa-180579.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-344238.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-362164.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-436469.pdf • CWE-342: Predictable Exact Value from Previous Values •
