Security Vulnerabilities - CVEs Published In July 2017
The Integrated User Firewall (UserFW) feature was introduced in Junos OS version 12.1X47-D10 on the Juniper SRX Series devices to provide simple integration of user profiles on top of the existing firewall polices. As part of an internal security review of the UserFW services authentication API, hardcoded credentials were identified and removed which can impact both the SRX Series device, and potentially LDAP and Active Directory integrated points. An attacker may be able to completely compromise SRX Series devices, as well as Active Directory servers and services. When Active Directory is compromised, it may allow access to user credentials, workstations, servers performing other functions such as email, database, etc. Inter-Forest Active Directory deployments may also be at risk as the attacker may gain full administrative control over one or more Active Directories depending on the credentials supplied by the administrator of the AD domains and SRX devices performing integrated authentication of users, groups and devices. To identify if your device is potentially vulnerable to exploitation, check to see if the service is operating; from CLI review the following output: root@SRX-Firewall# run show services user-identification active-directory-access domain-controller status extensive A result of "Status: Connected" will indicate that the service is active on the device. To evaluate if user authentication is occurring through the device: root@SRX-Firewall# run show services user-identification active-directory-access active-directory-authentication-table all Next review the results to see if valid users and groups are returned. e.g. Domain: juniperlab.com Total entries: 3 Source IP Username groups state 172.16.26.1 administrator Valid 192.168.26.2 engg01 engineers Valid 192.168.26.3 guest01 guests Valid Domain: NULL Total entries: 8 Source IP Username groups state 192.168.26.4 Invalid 192.168.26.5 Invalid This will also indicate that Valid users and groups are authenticating through the device. Affected releases are Juniper Networks Junos OS 12.3X48 from 12.3X48-D30 and prior to 12.3X48-D35 on SRX series; 15.1X49 from 15.1X49-D40 and prior to 15.1X49-D50 on SRX series. Devices on any version of Junos OS 12.1X46, or 12.1X47 are unaffected by this issue.

A routine within an internal Junos OS sockets library is vulnerable to a buffer overflow. Malicious exploitation of this issue may lead to a denial of service (kernel panic) or be leveraged as a privilege escalation through local code execution. The routines are only accessible via programs running on the device itself, and veriexec restricts arbitrary programs from running on Junos OS. There are no known exploit vectors utilizing signed binaries shipped with Junos OS itself. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D67; 12.3X48 prior to 12.3X48-D51, 12.3X48-D55; 13.3 prior to 13.3R10-S2; 14.1 prior to 14.1R2-S10, 14.1R8-S4, 14.1R9; 14.1X50 prior to 14.1X50-D185; 14.1X53 prior to 14.1X53-D122, 14.1X53-D45, 14.1X53-D50; 14.2 prior to 14.2R4-S9, 14.2R7-S7, 14.2R8; 15.1 prior to 15.1F2-S18, 15.1F6-S7, 15.1R4-S8, 15.1R5-S5, 15.1R6-S1, 15.1R7; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D231, 15.1X53-D47, 15.1X53-D48, 15.1X53-D57, 15.1X53-D64, 15.1X53-D70; 16.1 prior to 16.1R3-S4, 16.1R4-S3, 16.1R4-S4, 16.1R5; 16.2 prior to 16.2R2; 17.1 prior to 17.1R1-S3, 17.1R2; 17.2 prior to 17.2R1-S1, 17.2R2; 17.2X75 prior to 17.2X75-D30.

On Junos OS devices with SNMP enabled, a network based attacker with unfiltered access to the RE can cause the Junos OS snmpd daemon to crash and restart by sending a crafted SNMP packet. Repeated crashes of the snmpd daemon can result in a partial denial of service condition. Additionally, it may be possible to craft a malicious SNMP packet in a way that can result in remote code execution. SNMP is disabled in Junos OS by default. Junos OS devices with SNMP disabled are not affected by this issue. No other Juniper Networks products or platforms are affected by this issue. NOTE: This is a different issue than Cisco CVE-2017-6736, CVE-2017-6737, and CVE-2017-6738. Affected releases are Juniper Networks Junos OS 12.1X46 prior to 12.1X46-D67; 12.3X48 prior to 12.3X48-D51, 12.3X48-D55; 13.3 prior to 13.3R10-S2; 14.1 prior to 14.1R2-S10, 14.1R8-S4, 14.1R9; 14.1X50 prior to 14.1X50-D185; 14.1X53 prior to 14.1X53-D122, 14.1X53-D44, 14.1X53-D50; 14.2 prior to 14.2R4-S9, 14.2R7-S7, 14.2R8; 15.1 prior to 15.1F2-S18, 15.1F6-S7, 15.1R4-S8, 15.1R5-S5, 15.1R6-S1, 15.1R7; 15.1X49 prior to 15.1X49-D100, 15.1X49-D110; 15.1X53 prior to 15.1X53-D231, 15.1X53-D47, 15.1X53-D48, 15.1X53-D57, 15.1X53-D64, 15.1X53-D70; 16.1 prior to 16.1R3-S4, 16.1R4-S3, 16.1R4-S4, 16.1R5; 16.2 prior to 16.2R2, 16.2R3; 17.1 prior to 17.1R1-S3, 17.1R2, 17.1R3; 17.2 prior to 17.2R1-S1, 17.2R2; 17.2X75 prior to 17.2X75-D30.

An MS-MPC or MS-MIC Service PIC may crash when large fragmented packets are passed through an Application Layer Gateway (ALG). Repeated crashes of the Service PC can result in an extended denial of service condition. The issue can be seen only if NAT or stateful-firewall rules are configured with ALGs enabled. This issue was caused by the code change for PR 1182910 in Junos OS 14.1X55-D30, 14.1X55-D35, 14.2R7, 15.1R5, and 16.1R2. No other versions of Junos OS and no other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS on MX platforms running: 14.1X55 from 14.1X55-D30 to releases prior to 14.1X55-D35; 14.2R from 14.2R7 to releases prior to 14.2R7-S4, 14.2R8; 15.1R from 15.1R5 to releases prior to 15.1R5-S2, 15.1R6; 16.1R from 16.1R2 to releases prior to 16.1R3-S2, 16.1R4.
