Other file operations can be the next step. Opening the FCXE file is just the beginning. ![]() Here you will find a way to open your unknown FCXE file. One of the most used tools is FCXE opener. You can easily convert the file, preview its contents, or open and edit any FCXE file. They will help you use your FCXE file in the way you want. Devices on any version of Junos OS 12.1X46, or 12.1X47 are unaffected by this issue.Here are the most important online tools related to FCXE. 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. Domain: 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. To evaluate if user authentication is occurring through the device: # 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. To identify if your device is potentially vulnerable to exploitation, check to see if the service is operating from CLI review the following output: # 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. 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. When Active Directory is compromised, it may allow access to user credentials, workstations, servers performing other functions such as email, database, etc. An attacker may be able to completely compromise SRX Series devices, as well as Active Directory servers and services. 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. ![]() 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. ![]() No other Juniper Networks products or platforms are affected by this issue. There are no known exploit vectors utilizing signed binaries shipped with Junos OS itself. The routines are only accessible via programs running on the device itself, and veriexec restricts arbitrary programs from running on Junos OS. 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. A routine within an internal Junos OS sockets library is vulnerable to a buffer overflow.
