CVE-2020-1978 Detail

Current Description

TechSupport files generated on Palo Alto Networks VM Series firewalls for Microsoft Azure platform configured with high availability (HA) inadvertently collect Azure dashboard service account credentials. These credentials are equivalent to the credentials associated with the Contributor role in Azure. A user with the credentials will be able to manage all the Azure resources in the subscription except for granting access to other resources. These credentials do not allow login access to the VMs themselves. This issue affects VM Series Plugin versions before 1.0.9 for PAN-OS 9.0. This issue does not affect VM Series in non-HA configurations or on other cloud platforms. It does not affect hardware firewall appliances. Since becoming aware of the issue, Palo Alto Networks has safely deleted all the tech support files with the credentials. We now filter and remove these credentials from all TechSupport files sent to us. The TechSupport files uploaded to Palo Alto Networks systems were only accessible by authorized personnel with valid Palo Alto Networks credentials. We do not have any evidence of malicious access or use of these credentials.

Severity



CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  4.4 MEDIUM
Vector:  CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N

Nist CVSS score does not match with CNA score
CNA:  Palo Alto Networks, Inc.
Base Score:  5.8 MEDIUM
Vector:  CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:H


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
