Synopsis
The remote PAN-OS host is affected by multiple vulnerabilities.
Description
The version of Palo Alto Networks PAN-OS running on the remote host is 6.1.x prior to 6.1.18, 7.0.x prior to 7.0.17, 7.1.x prior to 7.1.12, or 8.0.x prior to 8.0.3. It is, therefore, affected by multiple vulnerabilities :
- A denial of service vulnerability exists in the OpenSSL component that is triggered when handling a large number of consecutive 'SSL3_AL_WARNING' undefined alerts. An unauthenticated, remote attacker can exploit this, by continuously sending warning alerts, to exhaust available CPU resources. Note that this vulnerability does not affect the 8.0.x version branch.
(CVE-2016-8610)
- A remote code execution vulnerability exists in the Linux kernel in udp.c due to an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag. An unauthenticated, remote attacker can exploit this, via specially crafted UDP traffic, to cause a denial of service condition or the execution of arbitrary code. Note that this vulnerability does not affect the 7.0.x version branch. (CVE-2016-10229)
- A remote code execution vulnerability exists in the DNS proxy service that is triggered when resolving fully qualified domain names (FQDN). An unauthenticated, remote attacker can exploit this to execute arbitrary code. Note that this vulnerability was fixed in version 7.1.10 for the 7.1.x version branch. (CVE-2017-8390)
- A XML external entity (XXE) vulnerability exists due to an incorrectly configured XML parser accepting XML from an untrusted source. An unauthenticated, remote attacker can exploit this by sending specially crafted XML data to the GlobalProtect external interface. Exploitation of this vulnerability may allow disclosure of information, denial of service or server side request forgery.
(CVE-2017-9458)
- A stored cross-site scripting (XSS) vulnerability exists in the Firewall web interface due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-9459)
- A cross-site scripting (XSS) vulnerability exists in the GlobalProtect component due to improper validation of user-supplied input to unspecified request parameters.
An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.
(CVE-2017-9467, CVE-2017-12416)
- A denial of service vulnerability exists that is triggered when the system attempts to close the connection of a rogue client that ignored the URL filtering block page. An unauthenticated, remote attacker can exploit this to crash the interface. Note that this vulnerability does not affect the 6.1.x and 7.0.x version branches.
Solution
Upgrade to Palo Alto Networks PAN-OS version 6.1.18 / 7.0.17 / 7.1.12 / 8.0.3 or later.
