This may be used to bypass IP based authentication on the origin server/ application. (CVE-2022-31813) Impact An unauthenticated attacker with network access to the data plane may exploit this vulnerability to bypass IP-based authentication on the origin server or application. Security Advisory Status F5 Product Development has assigned SDC-1981 and SDC-1980 (Traffix) and ID 1123105 (F5OS) to this vulnerability. This issue has been classified as CWE-345: Insufficient Verification of Data Authenticity. 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. Note: After a fix is introduced for a given minor branch, that fix applies to all subsequent maintenance and point releases for that branch, and no additional fixes for that branch will be listed in the table. For example, when a fix is introduced in 14.1.2.3, the fix also applies to 14.1.2.4, and all later 14.1.x releases (14.1.3.x., 14.1.4.x). For more information, refer to K51812227: Understanding security advisory versioning. Additionally, software versions preceding those listed in the Applies to (see versions) box of this article have reached the End of Technical Support (EoTS) phase of their lifecycle and are no longer evaluated for security issues. For more information, refer to the Security hotfixes section of K4602: Overview of the F5 security vulnerability response policy. +------------+------+-------------+----------+-----------+------+-------------+ | | |Versions |Fixes | |CVSSv3|Vulnerable | |Product |Branch|known to be |introduced|Severity |score^|component or | | | |vulnerable^1 |in | |2 |feature | +------------+------+-------------+----------+-----------+------+-------------+ | |17.x |None |Not | | | | | | | |applicable| | | | | +------+-------------+----------+ | | | | |16.x |None |Not | | | | | | | |applicable| | | | | +------+-------------+----------+Not | | | |BIG-IP (all |15.x |None |Not |vulnerable^|None |None | |modules) | | |applicable|3 | | | | +------+-------------+----------+ | | | | |14.x |None |Not | | | | | | | |applicable| | | | | +------+-------------+----------+ | | | | |13.x |None |Not | | | | | | | |applicable| | | | +------------+------+-------------+----------+-----------+------+-------------+ |BIG-IP SPK |1.x |None |Not |Not |None |None | | | | |applicable|vulnerable | | | +------------+------+-------------+----------+-----------+------+-------------+ | |8.x |None |Not | | | | |BIG-IQ | | |applicable|Not | | | |Centralized +------+-------------+----------+vulnerable |None |None | |Management |7.x |None |Not | | | | | | | |applicable| | | | +------------+------+-------------+----------+-----------+------+-------------+ |F5OS-A |1.x |1.0.0 - 1.1.1|None |High |7.3 |Apache httpd | +------------+------+-------------+----------+-----------+------+-------------+ | | |1.3.0 - 1.3.1| | | | | |F5OS-C |1.x |1.2.0 - 1.2.2|None |High |7.3 |Apache httpd | | | |1.1.0 - 1.1.4| | | | | +------------+------+-------------+----------+-----------+------+-------------+ |Traffix SDC |5.x |5.2.0 |None |High |7.3 |Apache httpd | | | |5.1.0 | | | | | +------------+------+-------------+----------+-----------+------+-------------+ ^1F5 evaluates only software versions that have not yet reached the End of Technical Support (EoTS) phase of their lifecycle. ^2The CVSSv3 score link takes you to a resource outside of AskF5, and it is possible that the document may be removed without our knowledge. ^3The specified products contain the affected code. However, F5 identifies the vulnerability status as Not vulnerable because the attacker cannot exploit the code in default, standard, or recommended configurations. Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by installing a version listed in the Fixes introduced in column. If the Fixes introduced in column does not list a version for your branch, then no update candidate currently exists for that branch and F5 recommends upgrading to a version with the fix (refer to the table). If the Fixes introduced in column lists a version prior to the one you are running, in the same branch, then your version should have the fix. Mitigation To mitigate this vulnerability for affected F5 products, you should restrict management access of F5 products to only trusted users and devices over a secure network.
