CVE-2018-0052 – Junos OS: Unauthenticated remote root access possible when RSH service is enabled

https://notcve.org/view.php?id=CVE-2018-0052

If RSH service is enabled on Junos OS and if the PAM authentication is disabled, a remote unauthenticated attacker can obtain root access to the device. RSH service is disabled by default on Junos. There is no documented CLI command to enable this service. However, an undocumented CLI command allows a privileged Junos user to enable RSH service and disable PAM, and hence expose the system to unauthenticated root access. When RSH is enabled, the device is listing to RSH connections on port 514. • http://www.securitytracker.com/id/1041853 https://kb.juniper.net/JSA10886 • CWE-287: Improper Authentication •

CVE-2018-0051 – Junos OS: Denial of Service vulnerability in MS-PIC, MS-MIC, MS-MPC, MS-DPC and SRX flow daemon (flowd) related to SIP ALG

https://notcve.org/view.php?id=CVE-2018-0051

A Denial of Service vulnerability in the SIP application layer gateway (ALG) component of Junos OS based platforms allows an attacker to crash MS-PIC, MS-MIC, MS-MPC, MS-DPC or SRX flow daemon (flowd) process. This issue affects Junos OS devices with NAT or stateful firewall configuration in combination with the SIP ALG enabled. SIP ALG is enabled by default on SRX Series devices except for SRX-HE devices. SRX-HE devices have SIP ALG disabled by default. The status of ALGs in SRX device can be obtained by executing the command: show security alg status Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D77; 12.3X48 versions prior to 12.3X48-D70; 15.1X49 versions prior to 15.1X49-D140; 15.1 versions prior to 15.1R4-S9, 15.1R7-S1; 15.1F6; 16.1 versions prior to 16.1R4-S9, 16.1R6-S1, 16.1R7; 16.2 versions prior to 16.2R2-S7, 16.2R3; 17.1 versions prior to 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.3 versions prior to 17.3R1-S5, 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R2. • http://www.securitytracker.com/id/1041852 https://kb.juniper.net/JSA10885 • CWE-20: Improper Input Validation •

CVE-2018-0043 – Junos OS: RPD daemon crashes upon receipt of specific MPLS packet

https://notcve.org/view.php?id=CVE-2018-0043

Receipt of a specific MPLS packet may cause the routing protocol daemon (RPD) process to crash and restart or may lead to remote code execution. By continuously sending specific MPLS packets, an attacker can repeatedly crash the RPD process causing a sustained Denial of Service. This issue affects both IPv4 and IPv6. This issue can only be exploited from within the MPLS domain. End-users connected to the CE device cannot cause this crash. • http://www.securitytracker.com/id/1041847 https://kb.juniper.net/JSA10877 • CWE-20: Improper Input Validation •
