Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Command injection

EUVDB-ID: #VU9662

Risk: High

CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2017-15944

CWE-ID: CWE-77 - Command injection

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary command on the target system.

The weakness exists due to multiple vulnerabilities in PAN-OS on Management Interface. A remote attacker can trigger deserialization error in processing the PHPSESSID cookie, modify the session file, cause an XML injection cookie injection error, bypass the panAuthCheck authentication directive controlling access to the '/php' directory, conduct an XML injection attack against the '/php/utils/router.php' script, create arbitrary directories, conduct a command injection attack against the '/usr/local/bin/genindex_batch.sh' cron script and execute arbitrary system commands with root privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update to version 6.1.19, 7.0.19, 7.1.14, 8.0.6.

Vulnerable software versions

Palo Alto PAN-OS: 6.1.0 - 8.0.5

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

Yes. This vulnerability is being exploited in the wild.

2) Denial of service

EUVDB-ID: #VU9663

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-15942

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to unspecified flaw in the management interface. A remote attacker can cause the target management interface to become unavailable.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Update to version 6.1.19, 7.0.19, 7.1.13, 8.0.6.

Vulnerable software versions

Palo Alto PAN-OS: 6.1.0 - 8.0.5

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Server-side request forgery

EUVDB-ID: #VU9665

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-15943

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The vulnerability allows a remote user to perform SSRF-attack on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can supply specially crafted configuration file data that references external entities, bypass security restrictions and obtain potentially sensitive information.

Mitigation

Update to version 6.1.19, 7.0.19, 7.1.14.

Vulnerable software versions

Palo Alto PAN-OS: 6.1.0 - 7.1.13

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

4) Command injection

EUVDB-ID: #VU9664

Risk: High

CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-15940

CWE-ID: CWE-77 - Command injection

Exploit availability: No

Description

The vulnerability allows a remote authenticated attacker to execute arbitrary command on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted data to the web interface packet capture management function to inject and execute arbitrary commands with root privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update to version 6.1.19, 7.0.19, 7.1.14.

Vulnerable software versions

Palo Alto PAN-OS: 6.1.0 - 7.1.13
