Security Advisory

1) Command injection

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.

Remediation

Update to version 6.1.19, 7.0.19, 7.1.14, 8.0.6.

2) Denial of service

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.

Remediation

Update to version 6.1.19, 7.0.19, 7.1.13, 8.0.6.

3) Server-side request forgery

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.

Remediation

Update to version 6.1.19, 7.0.19, 7.1.14.

4) Command injection

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.

Remediation

Update to version 6.1.19, 7.0.19, 7.1.14.
