(CVE-2020-5865) Impact An attacker can modify user entered data or run arbitrary SQL commands against the database server. Security Advisory Status F5 Product Development has assigned IND-6509 (NGINX) to this vulnerability. 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, point 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 |Not | | | | | | | |applicable| | | | | +------+----------+----------+ | | | | |14.x |None |Not | | | | |BIG-IP (LTM, AAM, | | |applicable| | | | |AFM, Analytics, +------+----------+----------+ | | | |APM, ASM, DNS, FPS,|13.x |None |Not |Not |None |None | |GTM, Link | | |applicable|Vulnerable| | | |Controller, PEM) +------+----------+----------+ | | | | |12.x |None |Not | | | | | | | |applicable| | | | | +------+----------+----------+ | | | | |11.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ | |7.x |None |Not | | | | | | | |applicable| | | | | +------+----------+----------+ | | | |BIG-IQ Centralized |6.x |None |Not |Not |None |None | |Management | | |applicable|vulnerable| | | | +------+----------+----------+ | | | | |5.x |None |Not | | | | | | | |applicable| | | | +-------------------+------+----------+----------+----------+------+----------+ |Traffix SDC |5.x |None |Not |Not |None |None | | | | |applicable|vulnerable| | | +-------------------+------+----------+----------+----------+------+----------+ | |3.x |3.0.0 - |3.3.0 | | | | | | |3.2.0 | | | | | | +------+----------+----------+ | |NGINX | |NGINX Controller |2.x |2.0.0 - |None |High |5.4 |Controller| | | |2.9.0 | | | | | | +------+----------+----------+ | | | | |1.x |1.0.1 |None | | | | +-------------------+------+----------+----------+----------+------+----------+ ^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. 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 ensure NGINX Controller communicates with the Postgres database server only over a secure network.
