Memory leak in the virtual server component in F5 Big-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Controller, and PEM 11.5.x before 11.5.1 HF10, 11.5.3 before HF1, and 11.6.0 before HF5, BIG-IQ Cloud, Device, and Security 4.4.0 through 4.5.0, and BIG-IQ ADC 4.5.0 allows remote attackers to cause a denial of service (memory consumption) via a large number of crafted ICMP packets.

The automatic signature update functionality in the (1) Phone Home feature in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, GTM, and Link Controller 11.5.0 through 11.6.0, ASM 10.0.0 through 11.6.0, and PEM 11.3.0 through 11.6.0 and the (2) Call Home feature in ASM 10.0.0 through 11.6.0 and PEM 11.3.0 through 11.6.0 does not properly validate server SSL certificates, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate.

Multiple XML External Entity (XXE) vulnerabilities in the Configuration utility in F5 BIG-IP LTM, ASM, GTM, and Link Controller 11.0 through 11.6.0 and 10.0.0 through 10.2.4, AAM 11.4.0 through 11.6.0, ARM 11.3.0 through 11.6.0, Analytics 11.0.0 through 11.6.0, APM and Edge Gateway 11.0.0 through 11.6.0 and 10.1.0 through 10.2.4, PEM 11.3.0 through 11.6.0, PSM 11.0.0 through 11.4.1 and 10.0.0 through 10.2.4, and WOM 11.0.0 through 11.3.0 and 10.0.0 through 10.2.4 and Enterprise Manager 3.0.0 through 3.1.1 and 2.1.0 through 2.3.0 allow remote authenticated users to read arbitrary files and cause a denial of service via a crafted request, as demonstrated using (1) viewList or (2) deal elements.

Cross-site scripting (XSS) vulnerability in tmui/dashboard/echo.jsp in the Configuration utility in F5 BIG-IP LTM, APM, ASM, GTM, and Link Controller 11.0.0 before 11.6.0 and 10.1.0 through 10.2.4, AAM 11.4.0 before 11.6.0, AFM and PEM 11.3.0 before 11.6.0, Analytics 11.0.0 through 11.5.1, Edge Gateway, WebAccelerator, and WOM 11.0.0 through 11.3.0 and 10.1.0 through 10.2.4, and PSM 11.0.0 through 11.4.1 and 10.1.0 through 10.2.4 and Enterprise Manager 3.0.0 through 3.1.1 and 2.1.0 through 2.3.0 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The rsync daemon in F5 BIG-IP 11.6 before 11.6.0, 11.5.1 before HF3, 11.5.0 before HF4, 11.4.1 before HF4, 11.4.0 before HF7, 11.3.0 before HF9, and 11.2.1 before HF11 and Enterprise Manager 3.x before 3.1.1 HF2, when configured in failover mode, does not require authentication, which allows remote attackers to read or write to arbitrary files via a cmi request to the ConfigSync IP address.

Cross-site scripting (XSS) vulnerability in list.jsp in the Configuration utility in F5 BIG-IP LTM, AFM, Analytics, APM, ASM, GTM, and Link Controller 11.2.1 through 11.5.1, AAM 11.4.0 through 11.5.1 PEM 11.3.0 through 11.5.1, PSM 11.2.1 through 11.4.1, WebAccelerator and WOM 11.2.1 through 11.3.0, and Enterprise Manager 3.0.0 through 3.1.1 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters.
