CVSS: 5.5EPSS: 0%CPEs: 288EXPL: 0CVE-2020-1630 – Junos OS: Privilege escalation vulnerability in dual REs, VC or HA cluster may allow unauthorized configuration change.
https://notcve.org/view.php?id=CVE-2020-1630
A privilege escalation vulnerability in Juniper Networks Junos OS devices configured with dual Routing Engines (RE), Virtual Chassis (VC) or high-availability cluster may allow a local authenticated low-privileged user with access to the shell to perform unauthorized configuration modification. This issue does not affect Junos OS device with single RE or stand-alone configuration. This issue affects Juniper Networks Junos OS 12.3 versions prior to 12.3R12-S14; 12.3X48 versions prior to 12.3X48-D86, 12.3X48-D90; 14.1X53 versions prior to 14.1X53-D51; 15.1 versions prior to 15.1R7-S6; 15.1X49 versions prior to 15.1X49-D181, 15.1X49-D190; 15.1X53 versions prior to 15.1X53-D592; 16.1 versions prior to 16.1R4-S13, 16.1R7-S6; 16.2 versions prior to 16.2R2-S10; 17.1 versions prior to 17.1R2-S11, 17.1R3-S1; 17.2 versions prior to 17.2R1-S9, 17.2R3-S3; 17.3 versions prior to 17.3R3-S6; 17.4 versions prior to 17.4R2-S6, 17.4R3; 18.1 versions prior to 18.1R3-S7; 18.2 versions prior to 18.2R2-S5, 18.2R3-S1; 18.2 versions prior to 18.2X75-D12, 18.2X75-D33, 18.2X75-D420, 18.2X75-D60, 18.2X75-D411; 18.3 versions prior to 18.3R1-S5, 18.3R2-S1, 18.3R3; 18.4 versions prior to 18.4R1-S4, 18.4R2-S1, 18.4R3; 19.1 versions prior to 19.1R1-S2, 19.1R2; 19.2 versions prior to 19.2R1-S1, 19.2R2. Una vulnerabilidad de escalada de privilegios en dispositivos Juniper Networks Junos OS configurados con Routing Engines (RE) duales (RE), Virtual Chassis (VC) o clúster de alta disponibilidad puede permitir que un usuario autenticado local poco privilegiado y acceso al shell lleve a cabo modificaciones de la configuración no autorizadas.

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 •
CVSS: 8.6EPSS: 0%CPEs: 344EXPL: 0CVE-2020-1613 – Junos OS: BGP session termination upon receipt of specific BGP FlowSpec advertisement.
https://notcve.org/view.php?id=CVE-2020-1613
A vulnerability in the BGP FlowSpec implementation may cause a Juniper Networks Junos OS device to terminate an established BGP session upon receiving a specific BGP FlowSpec advertisement. The BGP NOTIFICATION message that terminates an established BGP session is sent toward the peer device that originally sent the specific BGP FlowSpec advertisement. This specific BGP FlowSpec advertisement received from a BGP peer might get propagated from a Junos OS device running the fixed release to another device that is vulnerable causing BGP session termination downstream. This issue affects IPv4 and IPv6 BGP FlowSpec deployment. This issue affects Juniper Networks Junos OS: 12.3; 12.3X48 on SRX Series; 14.1X53 on EX and QFX Series; 15.1 versions prior to 15.1R7-S5; 15.1F versions prior to 15.1F6-S13; 15.1X49 versions prior to 15.1X49-D180 on SRX Series; 15.1X53 versions prior to 15.1X53-D238 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D497 on NFX Series; 15.1X53 versions prior to 15.1X53-D592 on EX2300/EX3400; 16.1 versions prior to 16.1R7-S7; 17.1 versions prior to 17.1R2-S12, 17.1R3; 17.2 versions prior to 17.2R2-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D102, 17.2X75-D110, 17.2X75-D44; 17.3 versions prior to 17.3R2-S5, 17.3R3-S5; 17.4 versions prior to 17.4R1-S8, 17.4R2; 18.1 versions prior to 18.1R2-S4, 18.1R3; 18.2X75 versions prior to 18.2X75-D20. • https://kb.juniper.net/JSA10996 • CWE-710: Improper Adherence to Coding Standards •

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') •
CVSS: 6.8EPSS: 0%CPEs: 16EXPL: 0CVE-2015-3006 – Junos: QFX Series: Insufficient entropy on QFX3500 and QFX3600 platforms when the system boots up
https://notcve.org/view.php?id=CVE-2015-3006
On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOM_INTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for some time, but immediately after boot, the entropy is very low. This issue only affects the QFX3500 and QFX3600 switches. No other Juniper Networks products or platforms are affected by this weak entropy vulnerability. En las plataformas QFX3500 y QFX3600, el número de bytes recopilados desde la fuente de entropía de RANDOM_INTERRUPT cuando los arranques del dispositivo son insuficientes, conllevando posiblemente a claves SSH débiles o duplicadas o a certificados SSL/TLS auto-firmados. • https://kb.juniper.net/JSA10678 • CWE-331: Insufficient Entropy •
