The wget library has been found to contain a vulnerability (CVE 2016-4971). wget allows remote servers to write to arbitrary files by redirecting a request from HTTP to a crafted FTP resource. Palo Alto Networks software makes use of the vulnerable library and may be affected. (Ref # PAN-59677/ CVE 2016-4971)
Successfully exploiting this issue would require an attacker to be authenticated on the Management Interface.
This issue affects PAN-OS 6.1.16 and earlier, PAN-OS 7.0.14 and earlier, PAN-OS 7.1.9 and earlier, PAN-OS 8.0
Work around:
Palo Alto Networks recommends to implement best practice by allowing web interface access only to a dedicated management network. Additionally, restrict the set of IP addresses to a subset of authorized sources that you allow to interact with the management network.
