Vulnerability Published: 2020-06-02
Patch Published: 2022-02-03
CVE [?]: CVE-2020-10878
CPE [?]: cpe:/a:f5:big-ip_access_policy_manager, cpe:/a:f5:big-ip_advanced_firewall_manager, cpe:/a:f5:big-ip_application_security_manager, cpe:/a:f5:big-ip_global_traffic_manager, cpe:/a:f5:big-ip_local_traffic_manager, cpe:/a:f5:big-ip_policy_enforcement_manager, cpe:/a:f5:big-ip_wan_optimization_manager, cpe:/h:f5:big-ip, cpe:/h:f5:big-ip_protocol_security_manager
Synopsis
The remote device is missing a vendor-supplied security patch.
Description
The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.4.5 / 15.1.4.1 / 15.1.5 / 16.1.2. It is, therefore, affected by a vulnerability as referenced in the K40508224 advisory.
- Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. (CVE-2020-10878)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade to one of the non-vulnerable versions listed in the F5 Solution K40508224.

- Run the scan.
Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.
Basic usage:
/opt/nessus/bin/nasl f5_bigip_SOL40508224.nasl -t <IP/HOST>
Run the plugin with audit trail message on the console:
/opt/nessus/bin/nasl -a f5_bigip_SOL40508224.nasl -t <IP/HOST>
Run the plugin with trace script execution written to the console (useful for debugging):
/opt/nessus/bin/nasl -T - f5_bigip_SOL40508224.nasl -t <IP/HOST>
Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):
/opt/nessus/bin/nasl -K /tmp/state f5_bigip_SOL40508224.nasl -t <IP/HOST>
Go back to menu.
