CVSS: 10.0EPSS: 0%CPEs: 123EXPL: 0CVE-2020-1615 – Junos OS: vMX: Default credentials supplied in vMX configuration
https://notcve.org/view.php?id=CVE-2020-1615
The factory configuration for vMX installations, as shipped, includes default credentials for the root account. Without proper modification of these default credentials by the administrator, an attacker could exploit these credentials and access the vMX instance without authorization. This issue affects Juniper Networks Junos OS: 17.1 versions prior to 17.1R2-S11, 17.1R3-S2 on vMX; 17.2 versions prior to 17.2R3-S3 on vMX; 17.3 versions prior to 17.3R2-S5, 17.3R3-S7 on vMX; 17.4 versions prior to 17.4R2-S9, 17.4R3 on vMX; 18.1 versions prior to 18.1R3-S9 on vMX; 18.2 versions prior to 18.2R2-S7, 18.2R3-S3 on vMX; 18.2X75 versions prior to 18.2X75-D420, 18.2X75-D60 on vMX; 18.3 versions prior to 18.3R1-S7, 18.3R2-S3, 18.3R3-S1 on vMX; 18.4 versions prior to 18.4R1-S5, 18.4R2-S3, 18.4R3 on vMX; 19.1 versions prior to 19.1R1-S4, 19.1R2, 19.1R3 on vMX; 19.2 versions prior to 19.2R1-S3, 19.2R2 on vMX; 19.3 versions prior to 19.3R1-S1, 19.3R2 on vMX. La configuración de fábrica para instalaciones de vMX, tal como es entregado, incluye credenciales predeterminadas para la cuenta root. Sin una modificación apropiada de estas credenciales predeterminadas por el administrador, un atacante podría explotar estas credenciales y acceder a la instancia de vMX sin autorización. • https://kb.juniper.net/JSA10998 • CWE-798: Use of Hard-coded Credentials •
CVSS: 10.0EPSS: 0%CPEs: 6EXPL: 0CVE-2020-1614 – NFX250 Series: Hardcoded credentials in the vSRX VNF instance.
https://notcve.org/view.php?id=CVE-2020-1614
A Use of Hard-coded Credentials vulnerability exists in the NFX250 Series for the vSRX Virtual Network Function (VNF) instance, which allows an attacker to take control of the vSRX VNF instance if they have the ability to access an administrative service (e.g. SSH) on the VNF, either locally, or through the network. This issue only affects the NFX250 Series vSRX VNF. No other products or platforms are affected. This issue is only applicable to environments where the vSRX VNF root password has not been configured. • https://kb.juniper.net/JSA10997 https://www.juniper.net/documentation/en_US/release-independent/junos/topics/task/configuration/nfx250-configure-vsrx-internal-ip.html • CWE-798: Use of Hard-coded Credentials •

https://notcve.org/view.php?id=CVE-2020-10188
utility.c in telnetd in netkit telnet through 0.17 allows remote attackers to execute arbitrary code via short writes or urgent data, because of a buffer overflow involving the netclear and nextitem functions. El archivo utility.c en telnetd en netkit telnet versiones hasta 0.17, permite a atacantes remotos ejecutar código arbitrario por medio de escrituras cortas o datos urgentes, debido a un desbordamiento del búfer que involucra a las funciones netclear y nextitem. A vulnerability was found where incorrect bounds checks in the telnet server’s (telnetd) handling of short writes and urgent data, could lead to information disclosure and corruption of heap data. An unauthenticated remote attacker could exploit these bugs by sending specially crafted telnet packets to achieve arbitrary code execution in the telnet server. • https://appgateresearch.blogspot.com/2020/02/bravestarr-fedora-31-netkit-telnetd_28.html https://github.com/krb5/krb5-appl/blob/d00cd671dfe945791b33d4f1f6a5c57ae1667ef8/telnet/telnetd/utility.c#L205-L216 https://lists.debian.org/debian-lts-announce/2020/05/msg00012.html https://lists.debian.org/debian-lts-announce/2020/08/msg00038.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7FMTRRQTYKWZD2GMXX3GLZV46OLPCLVK https://lists.fedoraproject.org/archives/list/package-announce%40l • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
