Buffer Overflow in the Management Web Interface (PAN-SA-2016-0035)

Last revised: 11/17/2016

Summary

Palo Alto Networks web management server improperly handles a buffer overflow. This can result in a possible remote code execution (RCE). (Ref # PAN-63073/102953/CVE-2016-9150)

Severity: Critical

An attacker with network access to the management web interface may be able to perform a remote code execution (RCE) or denial-of-service (DoS).

Products Affected

PAN-OS 5.0.19 and earlier; PAN-OS 5.1.12 and earlier; PAN-OS 6.0.14 and earlier; PAN-OS 6.1.14 and earlier; PAN-OS 7.0.10 and earlier; PAN-OS 7.1.5 and earlier

Available Updates

PAN-OS 5.0.20 and later; PAN-OS 5.1.13 and later; PAN-OS 6.0.15 and later; PAN-OS 6.1.15 and later; PAN-OS 7.0.11 and later; PAN-OS 7.1.6 and later

Workarounds and Mitigations

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.
