F5 iWorkflow 2.3.0

On BIG-IP ASM 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, and 13.1.0-13.1.3.1, BIG-IQ 6.0.0 and 5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, an attacker with access to the device communication between the BIG-IP ASM Central Policy Builder and the BIG-IQ/Enterprise Manager/F5 iWorkflow will be able to set up the proxy the same way and intercept the traffic.

Versions of lodash lower than 4.17.12 are vulnerable to Prototype Pollution. The function defaultsDeep could be tricked into adding or modifying properties of Object.prototype using a constructor payload.

In BIG-IP 15.0.0, 14.0.0-14.1.0.5, 13.0.0-13.1.1.5, 12.1.0-12.1.4.2, and 11.5.2-11.6.4, BIG-IQ 6.0.0-6.1.0 and 5.1.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, authenticated users with the ability to upload files (via scp, for example) can escalate their privileges to allow root shell access from within the TMOS Shell (tmsh) interface. The tmsh interface allows users to execute a secondary program via tools like sftp or scp.

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363.

Limiting simultaneous TCP clients was ineffective

The OSPFv3 parser in tcpdump before 4.9.3 has a buffer over-read in print-ospf6.c:ospf6_print_lshdr().

The FRF.16 parser in tcpdump before 4.9.3 has a buffer over-read in print-fr.c:mfr_print().

A race condition when discarding malformed packets can cause BIND to exit with an assertion failure

On BIG-IP 15.0.0-15.0.1.1, 14.1.0-14.1.2.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.6.0-11.6.5.1, the tmm crashes under certain circumstances when using the connector profile if a specific sequence of connections are made.

The BIG-IP 15.0.0-15.0.1, 14.0.0-14.1.2.2, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.1-11.6.5.1, BIG-IQ 7.0.0, 6.0.0-6.1.0, and 5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1 configuration utility is vulnerable to Anti DNS Pinning (DNS Rebinding) attack.

On BIG-IP versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, BIG-IQ versions 7.0.0, 6.0.0-6.1.0, and 5.0.0-5.4.0, iWorkflow version 2.3.0, and Enterprise Manager version 3.1.1, authenticated users granted TMOS Shell (tmsh) privileges are able access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to access objects on the file system which would not normally be allowed.

In BIG-IP 15.0.0, 14.1.0-14.1.0.6, 14.0.0-14.0.0.5, 13.0.0-13.1.1.5, 12.1.0-12.1.4.1, 11.5.1-11.6.4, BIG-IQ 7.0.0, 6.0.0-6.1.0,5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, the Configuration utility login page may not follow best security practices when handling a malicious request.
