This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as `node --debug=localhost `. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable. (CVE-2018-12120) Impact A remote attacker may be able to attach a remote computer to the debug port and evaluate arbitrary JavaScript. Security Advisory Status F5 Product Development has assigned ID 726327 (BIG-IP) and ID 752882 (BIG-IQ) to this vulnerability. Additionally, F5 iHealth may list Heuristic H37111863 on the Diagnostics > Identified > High page. To determine if your product and version have been evaluated for this vulnerability, refer to the Applies to (see versions) box. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table. For more information about security advisory versioning, refer to K51812227: Understanding Security Advisory versioning. +-------------------+------+----------+----------+----------+------+----------+ | | |Versions |Fixes | |CVSSv3|Vulnerable| |Product |Branch|known to |introduced|Severity |score^|component | | | |be |in | |1 |or feature| | | |vulnerable| | | | | +-------------------+------+----------+----------+----------+------+----------+ | |15.x |None |15.0.0 | | | | | +------+----------+----------+ | | | | |14.x |14.0.0 - |14.1.0.6 | | | | |BIG-IP (LTM, AAM, | |14.1.0 | | | | | |AFM, Analytics, +------+----------+----------+ | |iRulesLX | |APM, ASM, DNS, Edge|13.x |13.1.0 - |13.1.1.5 | | |use with | |Gateway, FPS, GTM, | |13.1.1 | |High |7.7 |the NodeJS| |Link Controller, +------+----------+----------+ | |^2 | |PEM, |12.x |None |Not | | | | |WebAccelerator) | | |applicable| | | | | +------+----------+----------+ | | | | |11.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ |Enterprise Manager |3.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ | |6.x |6.0.0 - |6.1.0 | | |iRulesLX | |BIG-IQ Centralized | |6.0.1 | | | |use with | |Management +------+----------+----------+High |7.7 |the NodeJS| | |5.x |5.2.0 - |None | | |^2 | | | |5.4.0 | | | | | +-------------------+------+----------+----------+----------+------+----------+ |F5 iWorkflow |2.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ | |5.x |None |Not | | | | | | | |applicable|Not | | | |Traffix SDC +------+----------+----------+vulnerable|None |None | | |4.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ ^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is possible that the document may be removed without our knowledge. ^2The BIG-IP component contains the affected code, but will not be active in a default or standard configuration unless iRulesLX is provisioned. The configuration to exploit this vulnerability requires that a BIG-IP system is running NodeJS v6.x and the extension configurations include -debug. Note: By default, the BIG-IP system does not listen on port 5858; the port is chosen from a range of high ports. Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Fixes introduced in column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation To mitigate this vulnerability, you should consider the following recommendations: o Permit management access to F5 products only over a secure network, and limit shell access to only trusted users. For more information about securing access to BIG-IP and Enterprise Manager systems, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 14.x) and K13092: Overview of securing access to the BIG-IP system. o Lock down management port access and configure the self IP port lockdown feature to disallow unneeded ports on all self IP addresses. For more information, refer to K13250: Overview of port lockdown behavior (10.x - 11.x) or K17333: Overview of port lockdown behavior (12.x - 14.x). o F5 recommends that you use the node debugger capabilities on a non-production BIG-IP system.
