Security Advisory

1) Path traversal

Risk: Medium

CVSSv3.1: 7.6 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-27871

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences within VulnerabilitySettings.aspx in SolarWinds Network Performance Monitor. A remote user can send a specially crafted HTTP request and create arbitrary files on the system in arbitrary directories.

Successful exploitation of the vulnerability can lead to arbitrary code execution in the context of SYSTEM account.

Mitigation

Install update from vendor's website.

3) SQL injection

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-27869

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the WriteToFile method in SolarWinds Network Performance Monitor. A remote user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to escalate privileges and reset the password for the Admin user.

Mitigation

Install updates from vendor's website.
